WEBVTT - The Three-Pupiled Eye, Part 2

0:00:03.040 --> 0:00:05.360
<v Speaker 1>Welcome to Stuff to Blow Your Mind production of My

0:00:05.480 --> 0:00:14.760
<v Speaker 1>Heart Radio. Hey, welcome to Stuff to Blow your Mind.

0:00:14.880 --> 0:00:17.800
<v Speaker 1>My name is Robert Lamb and I'm Joe McCormick. In

0:00:17.800 --> 0:00:22.239
<v Speaker 1>our last episode, we discussed a common but enthralling literary

0:00:22.320 --> 0:00:26.320
<v Speaker 1>motif in Irish mythology, the triple and the sevenfold I

0:00:26.800 --> 0:00:30.200
<v Speaker 1>three or seven pupils three or seven iris is found

0:00:30.200 --> 0:00:35.320
<v Speaker 1>in the eyes of beautiful heroes, divine seers, destructive monsters.

0:00:35.920 --> 0:00:38.880
<v Speaker 1>We also discussed the structure and functionality of the human

0:00:38.920 --> 0:00:42.080
<v Speaker 1>eye and the rare instances in which we actually see

0:00:42.520 --> 0:00:47.040
<v Speaker 1>double pupils in human eyes. In this episode, we're going

0:00:47.080 --> 0:00:50.120
<v Speaker 1>to explore more curious eyes from the natural world, as

0:00:50.159 --> 0:00:53.960
<v Speaker 1>well as more accounts of marvelous eyes from ancient history

0:00:53.960 --> 0:00:58.279
<v Speaker 1>and literature. But first, a pop culture update. Um At

0:00:58.280 --> 0:01:00.280
<v Speaker 1>the end of last episode we were talking about I

0:01:00.320 --> 0:01:05.000
<v Speaker 1>spoke briefly about some some double eyes that I've remembered

0:01:05.040 --> 0:01:08.760
<v Speaker 1>from some movies, album covers, etcetera. Well, Our our good

0:01:08.760 --> 0:01:12.639
<v Speaker 1>producer Seth provided us with two additional examples of double

0:01:12.680 --> 0:01:15.200
<v Speaker 1>eyes and popular culture that we didn't think of last time.

0:01:15.760 --> 0:01:19.600
<v Speaker 1>Number one, the double irises and pupils of aminet. In

0:01:19.720 --> 0:01:22.440
<v Speaker 1>two thousand, seventeens The Mummy. This is the Tom Cruise

0:01:22.520 --> 0:01:25.160
<v Speaker 1>Mummy film. Oh boy, did not see it, but I

0:01:25.160 --> 0:01:27.880
<v Speaker 1>think this is like the the titular Mummy, or at

0:01:27.959 --> 0:01:30.400
<v Speaker 1>least one of them. I think she is the Mummy

0:01:30.520 --> 0:01:32.840
<v Speaker 1>in this film. I'm okay, I haven't seen this one,

0:01:32.880 --> 0:01:36.160
<v Speaker 1>not even on an airplane, but I'm not opposed to it.

0:01:36.240 --> 0:01:38.919
<v Speaker 1>I mean, I've seen a lot of crummy Mummy movies

0:01:38.959 --> 0:01:42.600
<v Speaker 1>over the years, and usually there's something interesting in them. Yeah,

0:01:42.640 --> 0:01:46.680
<v Speaker 1>at least sometimes you get an Arnold Fosloo or something. Yeah. Uh.

0:01:46.720 --> 0:01:48.720
<v Speaker 1>And then the second example Seth brings up is the

0:01:48.720 --> 0:01:53.560
<v Speaker 1>album cover to Uh Bubba by Haitian Canadian musician um

0:01:53.760 --> 0:01:57.640
<v Speaker 1>K Trenada, featuring the artist with otherworldly blue eyes that

0:01:57.720 --> 0:02:01.160
<v Speaker 1>have double pupils, double irises. I listened to a track

0:02:01.240 --> 0:02:03.280
<v Speaker 1>from this album while we were working on notes. It

0:02:03.360 --> 0:02:05.080
<v Speaker 1>was good. I haven't had a chance yet, but I

0:02:05.120 --> 0:02:08.040
<v Speaker 1>do love the album cover. It's pretty great. Now. One

0:02:08.080 --> 0:02:11.880
<v Speaker 1>of the sources that we mentioned in the last episode

0:02:12.040 --> 0:02:16.400
<v Speaker 1>was the Evil Eye in early Irish literature and law.

0:02:16.680 --> 0:02:20.080
<v Speaker 1>This was published in Celtica twenty four back in two

0:02:20.120 --> 0:02:25.040
<v Speaker 1>thousand three. Uh and this was by Jacqueline borsch and Um,

0:02:25.120 --> 0:02:27.800
<v Speaker 1>the author of Fergus Kelly is also cited on this

0:02:28.240 --> 0:02:30.399
<v Speaker 1>paper because there's like a part one in a part two,

0:02:30.400 --> 0:02:32.799
<v Speaker 1>but I believe we were we dealt with material from

0:02:32.840 --> 0:02:36.080
<v Speaker 1>part one. Celtica. The journal this is in is a

0:02:36.080 --> 0:02:39.720
<v Speaker 1>scholarly journal for Celtic studies out of the Dublin Institute

0:02:39.720 --> 0:02:43.240
<v Speaker 1>for Advanced Studies. So most of this deals of course

0:02:43.240 --> 0:02:47.799
<v Speaker 1>with Irish law, Irish traditions, Irish mythology, UM, and UH

0:02:48.040 --> 0:02:51.800
<v Speaker 1>and in. Despite the popularity of this motif of the

0:02:52.280 --> 0:02:55.600
<v Speaker 1>of the multiple pupils, multiple irises within the Irish tradition,

0:02:55.840 --> 0:02:59.360
<v Speaker 1>we also encounter discussions of this sort of thing in

0:02:59.480 --> 0:03:03.080
<v Speaker 1>other traditions as well, and bor shares a few of

0:03:03.080 --> 0:03:06.839
<v Speaker 1>these well. The first one, UH comes to us from

0:03:06.880 --> 0:03:09.639
<v Speaker 1>a plenty of the Elder and the Natural History. Plenty

0:03:09.680 --> 0:03:13.840
<v Speaker 1>discusses individuals in Africa said to possess quote the power

0:03:13.919 --> 0:03:17.320
<v Speaker 1>of fascination with the eyes and can even kill those

0:03:17.400 --> 0:03:20.080
<v Speaker 1>on whom they fix their gaze for any length of time,

0:03:20.560 --> 0:03:24.040
<v Speaker 1>more especially if their look denotes anger. Now that's your

0:03:24.080 --> 0:03:28.440
<v Speaker 1>pretty basic evil eye scenario right there. And you encounter

0:03:28.520 --> 0:03:32.880
<v Speaker 1>variations of this through throughout the world. UH. Based on

0:03:32.960 --> 0:03:35.000
<v Speaker 1>the fact that, yes, you can shoot somebody a really

0:03:35.120 --> 0:03:39.520
<v Speaker 1>terrible look, and you can you can almost feel it.

0:03:39.680 --> 0:03:41.960
<v Speaker 1>Of course, going back into the ancient world, the belief

0:03:42.080 --> 0:03:44.360
<v Speaker 1>was often that it was more than you know, giving

0:03:44.400 --> 0:03:47.480
<v Speaker 1>somebody the stink I produced more than just a bad feeling,

0:03:47.520 --> 0:03:51.840
<v Speaker 1>that it could literally curse them or cause them magical harm. Yes,

0:03:52.320 --> 0:03:54.160
<v Speaker 1>But the neat thing here where it ties into what

0:03:54.160 --> 0:03:56.800
<v Speaker 1>we're talking about in these episodes is uh Plenty goes

0:03:56.840 --> 0:04:00.280
<v Speaker 1>on to connect this to multiple pupils quote. A still

0:04:00.320 --> 0:04:04.200
<v Speaker 1>more remarkable circumstance is the fact that these persons have

0:04:04.400 --> 0:04:08.920
<v Speaker 1>two pupils in each eye. Apollo Nides says that there

0:04:08.920 --> 0:04:12.480
<v Speaker 1>are certain females of this description in Scythia who are

0:04:12.560 --> 0:04:17.040
<v Speaker 1>known as the Bitha and Phi. Larches states that a

0:04:17.160 --> 0:04:21.200
<v Speaker 1>tribe of the Theebe in Pontus, and many other persons

0:04:21.240 --> 0:04:24.040
<v Speaker 1>as well have a double pupil in one eye and

0:04:24.080 --> 0:04:27.159
<v Speaker 1>in the other the figure of a horse. Double pupil

0:04:27.240 --> 0:04:30.760
<v Speaker 1>in one eye, the other the figure of a horse. Now,

0:04:30.760 --> 0:04:33.200
<v Speaker 1>with passages of this kind, we're often faced with the

0:04:33.320 --> 0:04:38.320
<v Speaker 1>question is this based on some distorted or exaggerated retelling

0:04:38.360 --> 0:04:42.000
<v Speaker 1>of something that somebody actually saw, or is it just

0:04:42.120 --> 0:04:46.560
<v Speaker 1>pure creative imagination or you know, tall tales, and it's

0:04:46.560 --> 0:04:49.440
<v Speaker 1>always interesting to wonder about the former, But ancient accounts

0:04:49.520 --> 0:04:52.719
<v Speaker 1>like Plenties are clearly full of the latter, especially when

0:04:53.040 --> 0:04:56.000
<v Speaker 1>telling stories about peoples who live in far away parts

0:04:56.000 --> 0:04:58.920
<v Speaker 1>of the globe. You know, this section that we're quoting

0:04:59.000 --> 0:05:01.400
<v Speaker 1>from Plenty is from I can't remember what it's called,

0:05:01.400 --> 0:05:03.400
<v Speaker 1>but there's like one of his books is all about

0:05:03.440 --> 0:05:05.960
<v Speaker 1>the nations of the world, and it's just all these

0:05:05.960 --> 0:05:08.599
<v Speaker 1>weird stories of like, here's a people who live somewhere

0:05:08.640 --> 0:05:11.680
<v Speaker 1>far away, and here's this strange thing they do or uh,

0:05:12.080 --> 0:05:14.640
<v Speaker 1>something that they wear that would be fascinating to to

0:05:14.760 --> 0:05:17.560
<v Speaker 1>my readers. Like there's one part where he talks about

0:05:17.600 --> 0:05:20.400
<v Speaker 1>a tribe of people somewhere who do not have heads

0:05:20.560 --> 0:05:24.680
<v Speaker 1>and instead have eyes in their breasts. So, uh, it

0:05:24.720 --> 0:05:27.640
<v Speaker 1>need not be the case that Plenty is necessarily here

0:05:27.680 --> 0:05:31.960
<v Speaker 1>repeating a misunderstood or exaggerated story about somebody who actually

0:05:32.000 --> 0:05:35.200
<v Speaker 1>had something like polycoria or some other unusual condition of

0:05:35.200 --> 0:05:38.760
<v Speaker 1>the pupils. But of course it is always possible. Yeah,

0:05:38.760 --> 0:05:40.960
<v Speaker 1>it does make make you wonder, you know, to what

0:05:41.080 --> 0:05:44.520
<v Speaker 1>extent would there be, like, you know, some account of

0:05:44.600 --> 0:05:48.520
<v Speaker 1>an individual with this this rare condition, uh, some memory

0:05:48.560 --> 0:05:51.040
<v Speaker 1>of this rare condition, and then it gets folded into

0:05:51.080 --> 0:05:54.720
<v Speaker 1>some of these traditions and beliefs at one point or

0:05:54.760 --> 0:05:57.680
<v Speaker 1>another in their long lives. Yes, though of course it

0:05:57.720 --> 0:06:00.560
<v Speaker 1>could again just be something somebody made, like the people

0:06:00.560 --> 0:06:02.760
<v Speaker 1>who don't have heads and have eyes in their breasts

0:06:03.279 --> 0:06:05.800
<v Speaker 1>right right, Like, we can dream up individuals with like

0:06:05.839 --> 0:06:08.960
<v Speaker 1>four arms, and it's pretty interesting and and we can

0:06:09.040 --> 0:06:11.719
<v Speaker 1>draw all sorts of meaning from that, But it doesn't

0:06:11.760 --> 0:06:14.920
<v Speaker 1>mean that that people with four arms ever actually existed,

0:06:15.279 --> 0:06:18.160
<v Speaker 1>you know, that there's any actual biological basis on which

0:06:18.160 --> 0:06:20.520
<v Speaker 1>that was based. Though. I do think it's really interesting

0:06:20.560 --> 0:06:22.640
<v Speaker 1>that he doesn't just say, okay, they've got two pupils

0:06:22.680 --> 0:06:25.640
<v Speaker 1>in each eye, but that they've got two pupils in

0:06:25.720 --> 0:06:28.919
<v Speaker 1>one eye and in the other eye a horse. Yeah,

0:06:29.000 --> 0:06:32.200
<v Speaker 1>And like my the first place my mind went was, Okay,

0:06:32.240 --> 0:06:34.680
<v Speaker 1>is it actually shaped like a horse a distortion that

0:06:34.800 --> 0:06:38.760
<v Speaker 1>is roughly horse shaped? Or is it Does it mean

0:06:38.760 --> 0:06:41.080
<v Speaker 1>that this is like some sort of telephone game, you know,

0:06:41.120 --> 0:06:45.280
<v Speaker 1>translation game version of horizontal pupil like one finds in

0:06:45.320 --> 0:06:47.640
<v Speaker 1>the eye of a horse. That's interesting and that will

0:06:47.680 --> 0:06:49.920
<v Speaker 1>tie into a scientific paper we're going to talk about

0:06:49.920 --> 0:06:53.440
<v Speaker 1>in a bit. I found an editor's footnote in the

0:06:54.200 --> 0:06:57.880
<v Speaker 1>Bostock translation of Plenty, which notes, quote, some of the

0:06:57.920 --> 0:07:02.480
<v Speaker 1>commentators have supposed Plenty or phi Larcis, from whom he borrows,

0:07:02.480 --> 0:07:05.479
<v Speaker 1>because remember, this isn't an original observation of Plenties. He's

0:07:05.520 --> 0:07:08.360
<v Speaker 1>like copying this from some other writing of this person

0:07:08.480 --> 0:07:11.400
<v Speaker 1>named phar Larcas, but phil Arcis from whom he borrows.

0:07:12.120 --> 0:07:15.640
<v Speaker 1>Whether they were misled by the ambiguity of the Greek

0:07:15.800 --> 0:07:21.760
<v Speaker 1>term eCos, which signifies either a horse or a tremulous

0:07:21.840 --> 0:07:25.560
<v Speaker 1>motion of the eye. But even admitting this to be

0:07:25.600 --> 0:07:28.240
<v Speaker 1>the case, the wonder is scarcely diminished, for we have

0:07:28.360 --> 0:07:32.120
<v Speaker 1>the double pupil in one eye, while this supposed tremulous

0:07:32.160 --> 0:07:35.320
<v Speaker 1>motion is confined to the other. So so if Fostuck

0:07:35.440 --> 0:07:37.960
<v Speaker 1>is correct there, it's that this word had had a

0:07:38.000 --> 0:07:40.600
<v Speaker 1>double meaning, and one of them was like a you know,

0:07:40.640 --> 0:07:42.760
<v Speaker 1>a quivering of the eye. I guess I would assume

0:07:42.800 --> 0:07:47.080
<v Speaker 1>that's like when somebody's eyes twitching. But yeah, you wonder, well,

0:07:47.080 --> 0:07:49.280
<v Speaker 1>why why is it just that the other eyes twitching

0:07:49.360 --> 0:07:51.400
<v Speaker 1>when when the first eye has two pupils in it.

0:07:51.440 --> 0:07:54.440
<v Speaker 1>That's also strange. Maybe not as strange as a horse.

0:07:54.960 --> 0:07:56.720
<v Speaker 1>Um I was. I was looking for answers on this

0:07:56.800 --> 0:08:00.520
<v Speaker 1>as well, and I ran across the paper titled of

0:08:00.600 --> 0:08:03.600
<v Speaker 1>the Papula Duplex and Other Tokens of an Evil Eye

0:08:04.080 --> 0:08:09.000
<v Speaker 1>in the Light of Ophthalmology by Walton Brooks McDaniel, UM

0:08:09.080 --> 0:08:15.360
<v Speaker 1>and uh. According to Brooks, here one Dr Kirby flower Smith,

0:08:15.480 --> 0:08:18.960
<v Speaker 1>a professor of Latin and the at John Hopkins University,

0:08:18.960 --> 0:08:22.760
<v Speaker 1>who had I looked at had died in UH interpreted

0:08:22.760 --> 0:08:26.440
<v Speaker 1>the Plenty passage as having some sort of connection to

0:08:26.480 --> 0:08:28.800
<v Speaker 1>the idea that the affliction of the eye was caused

0:08:28.800 --> 0:08:34.000
<v Speaker 1>by quote a horse shaped demon, horsehead mask demon. Yeah.

0:08:34.640 --> 0:08:38.120
<v Speaker 1>McDaniel also begins to discuss the the idea that if you,

0:08:38.120 --> 0:08:40.760
<v Speaker 1>you know, if you look into another eye, you know,

0:08:40.840 --> 0:08:43.160
<v Speaker 1>certainly with the right lighting and so forth, you look

0:08:43.160 --> 0:08:45.400
<v Speaker 1>into another person's eye, you can see your own reflection.

0:08:46.040 --> 0:08:51.040
<v Speaker 1>And so McDaniel mentions that, UH, in some traditions, that

0:08:51.040 --> 0:08:54.680
<v Speaker 1>that individual you see in the eye is interpreted, you know,

0:08:54.720 --> 0:08:58.120
<v Speaker 1>not as yourself, but as the signifier of the soul,

0:08:58.600 --> 0:09:00.840
<v Speaker 1>and that there are even some tradition where if the

0:09:00.920 --> 0:09:05.160
<v Speaker 1>individual looks in some way inverted, that is because of witchcraft.

0:09:06.520 --> 0:09:08.640
<v Speaker 1>And in this uh, this this is one of those

0:09:08.679 --> 0:09:13.079
<v Speaker 1>weird situations where then McDaniel mentioned something else that leads

0:09:13.120 --> 0:09:15.520
<v Speaker 1>me back to a source that I'm I'm very familiar with,

0:09:15.600 --> 0:09:19.720
<v Speaker 1>and yet I totally blinked on this particular detail or

0:09:20.080 --> 0:09:22.520
<v Speaker 1>or or maybe I've never read this one particular tale,

0:09:22.800 --> 0:09:27.319
<v Speaker 1>but he ends up referring back to Strange Tales from

0:09:27.320 --> 0:09:30.760
<v Speaker 1>a Chinese studio by Poosh song Ling. That's a show, favorite, folks.

0:09:30.840 --> 0:09:32.640
<v Speaker 1>Should we do we have a strange sales from a

0:09:32.720 --> 0:09:36.800
<v Speaker 1>Chinese studio buzzer? I doubt we do, But at any rate,

0:09:36.880 --> 0:09:38.680
<v Speaker 1>it's it's it's a book that I really enjoy. This

0:09:38.720 --> 0:09:42.760
<v Speaker 1>is a Ching Dynasty um collection of stories that Pouh

0:09:42.840 --> 0:09:45.959
<v Speaker 1>song Ling collected and retails. And you know, there's a

0:09:46.000 --> 0:09:50.000
<v Speaker 1>lot that's that's lost in translation um out of Mandarin,

0:09:50.400 --> 0:09:54.920
<v Speaker 1>but but there's still remarkable fun sometimes funny, and sometimes

0:09:54.920 --> 0:09:58.280
<v Speaker 1>just very strange. Uh. Sometimes it's it's you know, it's

0:09:58.360 --> 0:10:00.200
<v Speaker 1>it's all about what they would have meant to the

0:10:00.200 --> 0:10:02.160
<v Speaker 1>people who read them. But there are a lot of

0:10:02.200 --> 0:10:06.280
<v Speaker 1>fun Uh. There's a Penguin edition of it translation that

0:10:06.360 --> 0:10:09.400
<v Speaker 1>I've I read again and again over the years, and

0:10:09.520 --> 0:10:12.600
<v Speaker 1>yet I completely blanked on this one story. It's called

0:10:12.760 --> 0:10:15.880
<v Speaker 1>Talking Pupils. I think maybe the reason that I haven't

0:10:15.920 --> 0:10:19.200
<v Speaker 1>read this one recently is sometimes i'll read these to

0:10:19.240 --> 0:10:21.599
<v Speaker 1>my son and I'll sort of glance at them, and

0:10:21.640 --> 0:10:23.839
<v Speaker 1>if it looks like there's something that might be scandalous

0:10:23.920 --> 0:10:25.880
<v Speaker 1>in it, or you know, a little dirty, then I'll

0:10:25.880 --> 0:10:28.960
<v Speaker 1>skip over the tale. There aren't many, but occasionally there's

0:10:28.960 --> 0:10:32.160
<v Speaker 1>one like that. So anyway, this story Talking Pupils concerns

0:10:32.200 --> 0:10:35.120
<v Speaker 1>the tale of one Feng Dong quote, a gentleman of

0:10:35.120 --> 0:10:38.480
<v Speaker 1>considerable accomplishments while at the same time having a reputation

0:10:38.800 --> 0:10:43.600
<v Speaker 1>as an unprincipled libertine. Oh yeah, so clearly that's why

0:10:43.640 --> 0:10:45.720
<v Speaker 1>I might have skipped over this in recent years. Anyway,

0:10:46.160 --> 0:10:49.079
<v Speaker 1>So Fang was this is how the story goes. Thing

0:10:49.200 --> 0:10:51.400
<v Speaker 1>is strolling the countryside and he happens on a fine

0:10:51.440 --> 0:10:54.880
<v Speaker 1>carriage on the road. Uh. One of the female attendants

0:10:55.120 --> 0:10:57.960
<v Speaker 1>to the carriage is quite fetching, so he moves in

0:10:57.960 --> 0:11:00.360
<v Speaker 1>for a closer look. But as he does so, he's

0:11:00.400 --> 0:11:03.040
<v Speaker 1>able to peek between the curtains of the carriage itself

0:11:03.080 --> 0:11:07.120
<v Speaker 1>and he sees a beautiful young woman within, and he's captivated.

0:11:07.400 --> 0:11:10.000
<v Speaker 1>The female attendant is having none of this, though, and

0:11:10.040 --> 0:11:13.240
<v Speaker 1>she verbally shames him. Uh, you know, call calls him

0:11:13.240 --> 0:11:15.400
<v Speaker 1>a you know, a weirdo and um, you know, a

0:11:15.440 --> 0:11:18.800
<v Speaker 1>snooper and uh, not only does she verbally shame him,

0:11:18.800 --> 0:11:21.080
<v Speaker 1>she reaches down, grabs some dust out of the road

0:11:21.520 --> 0:11:25.680
<v Speaker 1>and throws it in Fang's face. Oh, dirty fighter. Yeah,

0:11:25.720 --> 0:11:27.360
<v Speaker 1>but you know he had it coming. He was up

0:11:27.360 --> 0:11:30.360
<v Speaker 1>to no good and he gets punished for it. So

0:11:30.440 --> 0:11:32.800
<v Speaker 1>he's he's initially he's trying to get the dust out

0:11:32.800 --> 0:11:35.880
<v Speaker 1>of his eyes. The carriage carries on. When he is

0:11:35.920 --> 0:11:39.520
<v Speaker 1>able to see again, you know, struggling, the carriage is

0:11:39.600 --> 0:11:41.880
<v Speaker 1>is completely done. It's you know, it's vanished around the

0:11:41.880 --> 0:11:44.760
<v Speaker 1>bend or whatever. So he has heads on home, but

0:11:44.800 --> 0:11:47.400
<v Speaker 1>his eyes continue to bother him, so he seeks some help.

0:11:47.440 --> 0:11:51.080
<v Speaker 1>A friend looks into his eyes. Um, and this friend says, yeah,

0:11:51.080 --> 0:11:54.880
<v Speaker 1>there's a visible film over each of your eyeballs. And meanwhile,

0:11:54.920 --> 0:11:59.640
<v Speaker 1>tears won't stop flowing. In time, the film thickens and

0:11:59.679 --> 0:12:02.840
<v Speaker 1>a birls. What what is described as a spiral shaped

0:12:03.000 --> 0:12:08.000
<v Speaker 1>protuberance begins growing from his right eye, resisting all manner

0:12:08.000 --> 0:12:12.720
<v Speaker 1>of treatment. Eventually he's completely blind, and you know, he's

0:12:12.760 --> 0:12:16.440
<v Speaker 1>he's distraught over this. But he hears about a Buddhist

0:12:16.520 --> 0:12:19.600
<v Speaker 1>sutra known as the Sutra of Light, and it's said

0:12:19.640 --> 0:12:22.200
<v Speaker 1>to be able to heal eye ailments or ailments of

0:12:22.240 --> 0:12:25.720
<v Speaker 1>this sort. So he gets a sided friend to read

0:12:25.720 --> 0:12:28.080
<v Speaker 1>it to him, and he learns it by heart, and

0:12:28.120 --> 0:12:30.480
<v Speaker 1>he recites it over and over again, and after a

0:12:30.480 --> 0:12:33.200
<v Speaker 1>while it gives him solace. Uh, you know, he feels

0:12:33.200 --> 0:12:35.840
<v Speaker 1>a little better. His side is not back. But then

0:12:35.880 --> 0:12:39.600
<v Speaker 1>one day he begins to hear voices, two voices, one

0:12:39.679 --> 0:12:42.640
<v Speaker 1>from each of his eyeballs. Oh, I love this. The

0:12:42.640 --> 0:12:45.720
<v Speaker 1>eyeballs are talking, both of them. Well, as it turns out,

0:12:45.800 --> 0:12:49.000
<v Speaker 1>not the eyeballs, but things within the eyeballs. There's one

0:12:49.080 --> 0:12:52.160
<v Speaker 1>voice within each eyeball, and there they start talking to

0:12:52.200 --> 0:12:53.920
<v Speaker 1>each other, and they're talking about how dark it is

0:12:54.000 --> 0:12:56.600
<v Speaker 1>in their homes and how they'd really like to just

0:12:56.640 --> 0:12:58.800
<v Speaker 1>get outside and go for a stroll. And then so

0:12:58.920 --> 0:13:02.600
<v Speaker 1>puss on Ling says quote, then he felt a slight

0:13:02.640 --> 0:13:05.920
<v Speaker 1>irritation in both the nostrils, as if two little creatures

0:13:05.920 --> 0:13:08.960
<v Speaker 1>were wriggling down his nose. After a while, he felt

0:13:08.960 --> 0:13:11.800
<v Speaker 1>the creatures return and make their way back up his nostrils.

0:13:12.120 --> 0:13:16.280
<v Speaker 1>And into the eye sockets. Again, this is anatomically correct because,

0:13:16.360 --> 0:13:20.200
<v Speaker 1>as we know, the tear ducks that drained tears away

0:13:20.240 --> 0:13:23.640
<v Speaker 1>from the eyes drained into the nasal cavity, which is

0:13:23.640 --> 0:13:28.240
<v Speaker 1>why your nose runs when you cry. Very good. So, uh,

0:13:28.600 --> 0:13:30.720
<v Speaker 1>what does thing do at this point? Well, he gets

0:13:30.720 --> 0:13:32.720
<v Speaker 1>his wife to take him to the old garden, and

0:13:32.720 --> 0:13:34.839
<v Speaker 1>he has her observe him in the garden to see

0:13:34.840 --> 0:13:37.200
<v Speaker 1>if anything like this happens again. Maybe the garden will

0:13:37.480 --> 0:13:40.720
<v Speaker 1>coax whatever it is out of his eyeballs. And this

0:13:40.800 --> 0:13:43.360
<v Speaker 1>is what happens. Quote, it was not long before she

0:13:43.440 --> 0:13:47.040
<v Speaker 1>saw two little mannekins, neither of them any larger than

0:13:47.080 --> 0:13:50.360
<v Speaker 1>a bean, emerged from his nose and fly buzzing out

0:13:50.400 --> 0:13:52.880
<v Speaker 1>of the door. They were soon well out of sight.

0:13:53.280 --> 0:13:56.200
<v Speaker 1>But we're back again in next to no time, flying

0:13:56.280 --> 0:13:59.520
<v Speaker 1>together up onto his face and in at his nostrils,

0:13:59.559 --> 0:14:02.640
<v Speaker 1>like a pair of homing bees or ants. So is

0:14:02.640 --> 0:14:06.440
<v Speaker 1>he getting relief when they fly away? I don't think so. No,

0:14:07.120 --> 0:14:09.800
<v Speaker 1>It's just it happens, and he doesn't know what this

0:14:09.880 --> 0:14:13.079
<v Speaker 1>is about. So and it keeps happening. It happens again

0:14:13.240 --> 0:14:15.720
<v Speaker 1>each day for three days, and finally one of the

0:14:15.800 --> 0:14:19.560
<v Speaker 1>voices complains that the tunnel that they're using to get

0:14:19.560 --> 0:14:22.160
<v Speaker 1>out of the eyeball is a bit round about, uh,

0:14:22.320 --> 0:14:25.040
<v Speaker 1>and there's got to be a better way, right, It's

0:14:25.120 --> 0:14:28.560
<v Speaker 1>time that they make some sort of proper doorway. So

0:14:28.960 --> 0:14:31.440
<v Speaker 1>I'm going to read uh the rest of this year.

0:14:31.480 --> 0:14:34.000
<v Speaker 1>That really gets to the juicy part. I'm just I'm

0:14:34.040 --> 0:14:36.040
<v Speaker 1>filled with dread. It's not a good idea when the

0:14:36.320 --> 0:14:39.440
<v Speaker 1>tenants in your eyeballs decided to start renovating on their own.

0:14:41.280 --> 0:14:44.480
<v Speaker 1>So that's how it goes. The wall on my side

0:14:44.520 --> 0:14:47.600
<v Speaker 1>is very thick, replied the right eye. It won't be easy.

0:14:47.720 --> 0:14:50.400
<v Speaker 1>I'll try to make an opening on my side, said

0:14:50.400 --> 0:14:54.320
<v Speaker 1>the left eye. Then we can share my door. Presently,

0:14:54.400 --> 0:14:57.600
<v Speaker 1>Fay thought he felt a scratching and a splitting in

0:14:57.680 --> 0:15:00.400
<v Speaker 1>his left eye socket, and an instant later he could

0:15:00.400 --> 0:15:03.280
<v Speaker 1>see he could see everything around him with absolute clarity,

0:15:03.320 --> 0:15:06.560
<v Speaker 1>beside himself with delight. He promptly informed his wife, who

0:15:06.560 --> 0:15:09.560
<v Speaker 1>inspected his eyes afresh and found that in the left

0:15:09.600 --> 0:15:12.920
<v Speaker 1>eye a minute aperture had appeared in the film, a

0:15:13.000 --> 0:15:16.480
<v Speaker 1>hole no larger than a cracked peppercorn, through which gleamed

0:15:16.520 --> 0:15:20.080
<v Speaker 1>the black globe of a pupil. By the next morning,

0:15:20.120 --> 0:15:23.280
<v Speaker 1>the film in the left eye had disappeared altogether. But

0:15:23.360 --> 0:15:26.040
<v Speaker 1>the strangest thing of all was that, on careful inspection,

0:15:26.120 --> 0:15:29.400
<v Speaker 1>there were now two pupils visible in that eye, and

0:15:29.480 --> 0:15:32.720
<v Speaker 1>the right eye was still obscured by its spiral shaped growth.

0:15:33.120 --> 0:15:37.360
<v Speaker 1>Apparently both of the two eye mannekins his talking pupils

0:15:37.600 --> 0:15:41.000
<v Speaker 1>had now taken up residence in the left eye. So

0:15:41.080 --> 0:15:44.080
<v Speaker 1>although Fang was still blind in one eye, he could

0:15:44.080 --> 0:15:46.720
<v Speaker 1>see better with his one good eye than he had

0:15:46.720 --> 0:15:49.840
<v Speaker 1>ever done with two. From that day forth he was

0:15:49.880 --> 0:15:53.160
<v Speaker 1>a great deal more circumspect in his behavior and acquired

0:15:53.280 --> 0:15:57.440
<v Speaker 1>unimpeccable reputation in the district. Okay, so no more creeping

0:15:57.520 --> 0:16:00.400
<v Speaker 1>on ladies and carriages. Right, he learned his uson. He

0:16:00.400 --> 0:16:03.720
<v Speaker 1>was you know, punished for his creepy behavior, and now

0:16:03.720 --> 0:16:06.400
<v Speaker 1>he's back and ready to be a good citizen with

0:16:06.480 --> 0:16:09.280
<v Speaker 1>one eye that can see better than two, right, because

0:16:09.320 --> 0:16:12.200
<v Speaker 1>two pupils um Now that this again is from the

0:16:12.200 --> 0:16:16.480
<v Speaker 1>Penguin Classics edition. It's a John Minford translation, and this

0:16:16.560 --> 0:16:19.280
<v Speaker 1>was super interesting as well. Minford shares this in the

0:16:19.320 --> 0:16:24.200
<v Speaker 1>notes Pupils. The traditional Chinese expression for pupil, tong wren,

0:16:24.920 --> 0:16:28.920
<v Speaker 1>means literally man in the pupil from the reflection of

0:16:28.960 --> 0:16:33.360
<v Speaker 1>oneself that one sees in the eye of another. Yeah,

0:16:33.520 --> 0:16:35.520
<v Speaker 1>that was that was really that. I was really impressed

0:16:35.560 --> 0:16:37.240
<v Speaker 1>by that. And I was talking to my wife about

0:16:37.280 --> 0:16:39.720
<v Speaker 1>it because I was looking around a little bit after this,

0:16:39.800 --> 0:16:43.320
<v Speaker 1>and I saw an article about photography and about being

0:16:43.360 --> 0:16:46.120
<v Speaker 1>able to zoom in on the eye of an individual

0:16:46.200 --> 0:16:49.760
<v Speaker 1>in a modern photograph and see the reflection potentially of

0:16:49.800 --> 0:16:56.000
<v Speaker 1>the photographer and because of the high resolution, I guess, yeah, yeah,

0:16:56.120 --> 0:16:58.200
<v Speaker 1>and uh. I was asking my wife about this, and

0:16:58.280 --> 0:17:01.600
<v Speaker 1>she pointed out that one the photographers can do is

0:17:01.640 --> 0:17:03.760
<v Speaker 1>you can pull up, say a head shot that another

0:17:03.760 --> 0:17:06.960
<v Speaker 1>photographer has done. You can zoom in on the eye

0:17:07.040 --> 0:17:09.280
<v Speaker 1>and you can see what they're lighting set up is.

0:17:10.640 --> 0:17:13.400
<v Speaker 1>So I was impressed by that as well. I'm impressed.

0:17:13.440 --> 0:17:15.919
<v Speaker 1>That's a real James Bond level trick. I do not

0:17:16.080 --> 0:17:18.320
<v Speaker 1>know what to make of the spiral growth though. Um.

0:17:18.359 --> 0:17:20.960
<v Speaker 1>I looked around briefly on that, and I was not

0:17:21.080 --> 0:17:25.399
<v Speaker 1>able to find any answers that seemed up convincing. I

0:17:25.440 --> 0:17:35.040
<v Speaker 1>have no expertise on spiral growths from eyes than all right,

0:17:35.080 --> 0:17:36.879
<v Speaker 1>I want to go back to Borsch for just a

0:17:36.880 --> 0:17:40.119
<v Speaker 1>minute here, because she has a couple of other examples

0:17:40.119 --> 0:17:46.320
<v Speaker 1>that she brings up. One apparently uh tolomeos chinos um Uh.

0:17:46.359 --> 0:17:49.000
<v Speaker 1>This would have been a figure from the late first

0:17:49.119 --> 0:17:53.320
<v Speaker 1>early second centuries. CE once described a beautiful woman as

0:17:53.359 --> 0:17:56.240
<v Speaker 1>being quote with a double pupil. Okay. And in the

0:17:56.320 --> 0:17:59.520
<v Speaker 1>last episode we we talked about some legends in which

0:17:59.560 --> 0:18:03.080
<v Speaker 1>a cure or with multiple pupils that this was assumed

0:18:03.119 --> 0:18:05.520
<v Speaker 1>to be a marker of beauty. Right. So this is

0:18:05.560 --> 0:18:08.000
<v Speaker 1>interesting because it seems to suggest that this is not

0:18:08.080 --> 0:18:13.240
<v Speaker 1>just isolated within Irish literary traditions, that perhaps somewhere else

0:18:13.240 --> 0:18:16.000
<v Speaker 1>in the world there was this idea that double pupil

0:18:16.080 --> 0:18:18.800
<v Speaker 1>equals beauty. Um. And and I mean, who am I

0:18:18.800 --> 0:18:21.200
<v Speaker 1>to say it's it's not beautiful? Uh? You know, it's

0:18:21.200 --> 0:18:23.640
<v Speaker 1>not like you look at images of of of actual

0:18:23.960 --> 0:18:27.520
<v Speaker 1>double pupil situations and you're not hortified by them or anything,

0:18:27.560 --> 0:18:29.000
<v Speaker 1>no more so than if you, you know, look at

0:18:29.000 --> 0:18:31.720
<v Speaker 1>a super close up of of of any human eyeball.

0:18:32.000 --> 0:18:35.960
<v Speaker 1>Borse also mentions that ovid portrays a woman with double

0:18:36.000 --> 0:18:39.400
<v Speaker 1>pupils having the evil eye at one point, so uh,

0:18:39.600 --> 0:18:42.920
<v Speaker 1>tying back into the evil eye tradition. But anyway, boris

0:18:43.000 --> 0:18:46.159
<v Speaker 1>concludes quote to conclude this section. Both angry eyes and

0:18:46.280 --> 0:18:49.760
<v Speaker 1>eyes with multiple pupils have been connected with the concept

0:18:49.760 --> 0:18:53.040
<v Speaker 1>of the evil eye. There is no strict identity between

0:18:53.080 --> 0:18:56.600
<v Speaker 1>the phenomena. Multiple pupils can also be a sign of beauty,

0:18:56.840 --> 0:19:00.200
<v Speaker 1>sharp sight, and clair avoyance. Okay, so we're not really

0:19:00.240 --> 0:19:03.720
<v Speaker 1>converging on a unity of theme here. It's if you're

0:19:03.720 --> 0:19:05.920
<v Speaker 1>in an Irish legendar myth and you have a character

0:19:06.000 --> 0:19:08.840
<v Speaker 1>with multiple pupils in one eye, it seems they could

0:19:08.920 --> 0:19:12.399
<v Speaker 1>either be somebody who has a lot of insight, somebody

0:19:12.440 --> 0:19:14.920
<v Speaker 1>who can see very far away, somebody who can see

0:19:14.920 --> 0:19:18.720
<v Speaker 1>the future, somebody who is beautiful, or somebody who is

0:19:18.840 --> 0:19:22.520
<v Speaker 1>monstrous or can do curses. And you know, there is

0:19:22.560 --> 0:19:24.720
<v Speaker 1>this idea too that it's it's part of like the

0:19:24.760 --> 0:19:27.520
<v Speaker 1>supernatural body, that when you have some sort of a

0:19:27.600 --> 0:19:32.159
<v Speaker 1>demigod figure, it's the human body. Um, it's almost like

0:19:32.160 --> 0:19:35.280
<v Speaker 1>it mutates with the divinity within it, like the like

0:19:35.320 --> 0:19:37.959
<v Speaker 1>the the human The normal human body cannot contain this

0:19:38.080 --> 0:19:41.600
<v Speaker 1>level of power, and therefore extra things are going to happen,

0:19:41.680 --> 0:19:45.000
<v Speaker 1>you know, extra pupils, extra fingers, that sort of thing.

0:19:46.080 --> 0:19:49.639
<v Speaker 1>And this ties directly into another example. I found, and

0:19:49.680 --> 0:19:53.640
<v Speaker 1>this one comes from Chinese traditions as well. Uh. This

0:19:53.720 --> 0:19:58.280
<v Speaker 1>is from the nine seven book Chinese Civilization and Bureaucracy,

0:19:58.720 --> 0:20:03.640
<v Speaker 1>Variations on a theme by Hungarian born French sinologists Eten

0:20:03.800 --> 0:20:09.639
<v Speaker 1>Belahs working with working from another source as well, Essay

0:20:09.720 --> 0:20:13.200
<v Speaker 1>on the Extinction of the Soul by Faun Shin, a

0:20:13.320 --> 0:20:17.879
<v Speaker 1>Chinese philosopher and writer who lived UH four fifty through five.

0:20:19.880 --> 0:20:22.840
<v Speaker 1>The subject here, as far as eyes are concerned, is

0:20:23.119 --> 0:20:26.919
<v Speaker 1>one of the legendary sage rulers of antiquity in China.

0:20:27.000 --> 0:20:30.080
<v Speaker 1>This would concern a time during the third millennium b c.

0:20:30.960 --> 0:20:33.879
<v Speaker 1>And so the structure of this paper seems to concern

0:20:34.080 --> 0:20:37.080
<v Speaker 1>like questions and answers. And so first we have this question.

0:20:37.720 --> 0:20:40.000
<v Speaker 1>The body of the sage is similar to the body

0:20:40.040 --> 0:20:42.520
<v Speaker 1>of ordinary men, Yet there is a difference by which

0:20:42.560 --> 0:20:45.840
<v Speaker 1>the sage is distinguished from ordinary men. From this, it

0:20:45.880 --> 0:20:49.800
<v Speaker 1>can be inferred that body and soul are different. Answer

0:20:50.359 --> 0:20:54.480
<v Speaker 1>not at all. Pure gold glitters, and unwashed gold does not.

0:20:55.119 --> 0:20:58.000
<v Speaker 1>Pure gold that glitters surely cannot be made of the

0:20:58.080 --> 0:21:02.400
<v Speaker 1>same unglittering material as out of unwashed gold. How much

0:21:02.520 --> 0:21:05.640
<v Speaker 1>less then, can the soul of a sage be lodged

0:21:05.680 --> 0:21:09.440
<v Speaker 1>in a vessel such as the ordinary man, Nor would

0:21:09.480 --> 0:21:12.000
<v Speaker 1>it be possible for the soul of an ordinary man

0:21:12.160 --> 0:21:15.520
<v Speaker 1>to dwell in the body of a sage. Therefore, fang

0:21:15.680 --> 0:21:19.840
<v Speaker 1>soon Is is depicted as having eyebrows of eight colors,

0:21:20.240 --> 0:21:25.000
<v Speaker 1>and zong Huo's eyes with double pupils, Seyon as having

0:21:25.000 --> 0:21:28.320
<v Speaker 1>the face of a dragon, and tie how the mouth

0:21:28.400 --> 0:21:31.960
<v Speaker 1>of a horse, all of which are outward bodily signs

0:21:32.000 --> 0:21:36.000
<v Speaker 1>of their exceptional nature. All the seven openings were found

0:21:36.040 --> 0:21:39.000
<v Speaker 1>in the heart of pie Con. The gall bladder of

0:21:39.080 --> 0:21:42.119
<v Speaker 1>Poe Yu was as big as a fist, which shows

0:21:42.160 --> 0:21:45.560
<v Speaker 1>that their inner organs were unusual. Thus we know that

0:21:45.680 --> 0:21:48.840
<v Speaker 1>certain parts of the bodies of sages are quite out

0:21:48.840 --> 0:21:51.960
<v Speaker 1>of the ordinary, and that sages are not only superior

0:21:52.000 --> 0:21:56.560
<v Speaker 1>to ordinary human beings, but also surpass all other creatures

0:21:56.600 --> 0:22:01.840
<v Speaker 1>in bodily form. That's just science. I I love this

0:22:01.880 --> 0:22:04.399
<v Speaker 1>passage so much. I mean, I love that it's basically

0:22:04.440 --> 0:22:09.800
<v Speaker 1>an autopsy of of supernatural sages determining how they're they're

0:22:09.800 --> 0:22:11.760
<v Speaker 1>But like you can imagine this scene in a movie.

0:22:12.080 --> 0:22:14.440
<v Speaker 1>Oh yeah, this is beautiful. The gall bladder as big

0:22:14.480 --> 0:22:18.160
<v Speaker 1>as a fist, showing that the inner organs are unusual.

0:22:18.400 --> 0:22:20.239
<v Speaker 1>This is great, and you know, and this is not

0:22:21.160 --> 0:22:24.159
<v Speaker 1>This is not a totally unique view of the body

0:22:24.200 --> 0:22:27.399
<v Speaker 1>of the holy person or the saint. I mean, you know,

0:22:27.680 --> 0:22:30.840
<v Speaker 1>there are tons of traditions all around the world, including

0:22:30.880 --> 0:22:33.159
<v Speaker 1>like the idea that that certain types of saints or

0:22:33.240 --> 0:22:37.160
<v Speaker 1>holy people, because of their spiritual nature, their bodies would

0:22:37.160 --> 0:22:39.879
<v Speaker 1>be found to be say, incorruptible, like they don't rot

0:22:40.000 --> 0:22:43.720
<v Speaker 1>the way most spoties do. Yeah so, but Balas add

0:22:43.760 --> 0:22:46.040
<v Speaker 1>some notes on this and points out that the legends

0:22:46.040 --> 0:22:49.240
<v Speaker 1>about the eyebrows of eight colors, uh and the eyes

0:22:49.240 --> 0:22:52.040
<v Speaker 1>with double pupils He's come from ma Han times and

0:22:52.080 --> 0:22:54.960
<v Speaker 1>are contained in a number of different works. Uh So,

0:22:55.040 --> 0:23:00.199
<v Speaker 1>yet another example of of of of exceptional eyes in

0:23:00.520 --> 0:23:04.960
<v Speaker 1>the bodies of exceptional you know, heroic mythic individuals. Now,

0:23:05.000 --> 0:23:07.200
<v Speaker 1>in the last episode, we talked a bit about human

0:23:07.280 --> 0:23:11.479
<v Speaker 1>eye anatomy and some medical literature on polycoria, or the

0:23:11.520 --> 0:23:14.960
<v Speaker 1>condition of having multiple pupils within the same eye. But

0:23:15.040 --> 0:23:16.760
<v Speaker 1>I thought in this episode it would be a good

0:23:16.760 --> 0:23:20.159
<v Speaker 1>idea to turn to pupils of the the animal kingdom

0:23:20.200 --> 0:23:22.960
<v Speaker 1>more broadly, because uh, there's a lot we can learn

0:23:23.000 --> 0:23:26.560
<v Speaker 1>about the function of pupils by looking at the pupils

0:23:26.640 --> 0:23:29.800
<v Speaker 1>of non human animals, that's right. I mean, just consider

0:23:30.359 --> 0:23:33.960
<v Speaker 1>the vast diversity we have in the animal world. Uh,

0:23:34.280 --> 0:23:36.880
<v Speaker 1>and I mean even just dealing with the vertebrate world,

0:23:36.960 --> 0:23:39.560
<v Speaker 1>it's pretty remarkable, not even getting into compound eyes of

0:23:39.920 --> 0:23:43.480
<v Speaker 1>flies and so forth. But uh, consider humans. We have

0:23:43.600 --> 0:23:48.960
<v Speaker 1>round pupils. House cats have vertical slits, tigers have round pupils,

0:23:49.040 --> 0:23:54.800
<v Speaker 1>goats and horses horizontal. Dolphins have crescents, cuttlefish have w

0:23:55.000 --> 0:24:00.360
<v Speaker 1>shaped pupils, some frogs have heart shaped pupils, and gets

0:24:00.359 --> 0:24:03.600
<v Speaker 1>have these sort of what looked like pinholes arranged in

0:24:03.640 --> 0:24:07.800
<v Speaker 1>a vertical line. I always love a good crocodile pupil. Oh, yes,

0:24:08.119 --> 0:24:10.600
<v Speaker 1>tend to be rather vertical. Yeah, it's and it's also

0:24:10.640 --> 0:24:13.360
<v Speaker 1>it's a window into the crocodile soul. But seeing all

0:24:13.440 --> 0:24:17.800
<v Speaker 1>this different diversity does raise some questions because you think, okay, well,

0:24:17.840 --> 0:24:22.400
<v Speaker 1>you know the bodies of animals are shaped by their environment.

0:24:22.640 --> 0:24:25.160
<v Speaker 1>You know that that's what evolution does. It tends to

0:24:25.359 --> 0:24:28.240
<v Speaker 1>give you the equipment that best helps you do whatever

0:24:28.280 --> 0:24:31.280
<v Speaker 1>you need to do within your ecological niche. So why

0:24:31.400 --> 0:24:34.879
<v Speaker 1>do different animals have different pupils. How how do differently

0:24:35.000 --> 0:24:39.160
<v Speaker 1>shaped or sized pupils help an animal adapt to how

0:24:39.160 --> 0:24:42.240
<v Speaker 1>it's supposed to survive in the world. Yeah. According to

0:24:42.359 --> 0:24:45.760
<v Speaker 1>Martin Banks, a vision scientists at the University of California

0:24:45.960 --> 0:24:50.000
<v Speaker 1>that cited in NPR story I, shapes of the animal

0:24:50.040 --> 0:24:53.679
<v Speaker 1>world hint at differences in our lifestyles. Land animals of

0:24:53.720 --> 0:24:56.919
<v Speaker 1>sufficient height tend to have round pupils. Thus you have

0:24:57.040 --> 0:25:01.480
<v Speaker 1>big cats that have round pupils. Meanwhile your your small

0:25:01.560 --> 0:25:05.240
<v Speaker 1>house cat cat has vertical pupils. Verticals are more the

0:25:05.280 --> 0:25:09.320
<v Speaker 1>domain it seems, of smaller ambush predators, giving them an

0:25:09.359 --> 0:25:13.080
<v Speaker 1>excellent ability at judging distances, which of course is going

0:25:13.119 --> 0:25:15.040
<v Speaker 1>to be super important when you're bouncing out of the

0:25:15.040 --> 0:25:18.840
<v Speaker 1>shadows and trying to um, you know, capture like a

0:25:18.920 --> 0:25:22.840
<v Speaker 1>small rodent or your owner's foot. Horizontal pupils, on the

0:25:22.880 --> 0:25:25.520
<v Speaker 1>other hand, are widely understood as a means of keeping

0:25:25.560 --> 0:25:29.200
<v Speaker 1>a wider swath of the surroundings in sight while you're

0:25:29.280 --> 0:25:32.760
<v Speaker 1>grazing um and you know, an expanded field of view.

0:25:32.880 --> 0:25:34.760
<v Speaker 1>So you can think of this, is that the panoramic

0:25:34.800 --> 0:25:38.359
<v Speaker 1>potential prey view of the world. Right, So I was

0:25:38.400 --> 0:25:41.720
<v Speaker 1>actually looking into this, Uh, the paper that Banks is

0:25:41.720 --> 0:25:45.760
<v Speaker 1>connected with is one that was published in in Science Advances,

0:25:46.280 --> 0:25:50.639
<v Speaker 1>and it's by Martin Banks, William Sprague, You're going small,

0:25:50.840 --> 0:25:54.480
<v Speaker 1>Jared Parnell, and Gordon Love, and it's called why do

0:25:54.640 --> 0:25:58.480
<v Speaker 1>animal ize have pupils of different shapes? And what you

0:25:58.520 --> 0:26:01.520
<v Speaker 1>say is correct? They looked in this question and they found, Yeah,

0:26:01.680 --> 0:26:05.520
<v Speaker 1>there are some very strong correlations between how an animals

0:26:05.600 --> 0:26:08.800
<v Speaker 1>survives and what shape its pupils are, at least among

0:26:09.080 --> 0:26:12.960
<v Speaker 1>land vertebrates. And so you tend to have, like you're saying,

0:26:12.960 --> 0:26:19.200
<v Speaker 1>horizontal pupils if you are a herbivore, whereas ambush predators

0:26:19.200 --> 0:26:21.080
<v Speaker 1>predators that sit around and wait for their prey, they

0:26:21.160 --> 0:26:24.879
<v Speaker 1>tend to have vertical slits, especially if they're active in

0:26:25.000 --> 0:26:30.439
<v Speaker 1>both daytime and nighttime. And meanwhile, active predators, predators that

0:26:31.280 --> 0:26:34.320
<v Speaker 1>hunt and chase down their prey instead of sitting and waiting,

0:26:34.640 --> 0:26:38.760
<v Speaker 1>they are more likely to have round or circular pupils.

0:26:39.200 --> 0:26:41.520
<v Speaker 1>And this is not a coincidence. The author has found

0:26:41.560 --> 0:26:45.679
<v Speaker 1>some pretty good reasons why the pupils would be allotted

0:26:45.720 --> 0:26:48.199
<v Speaker 1>in these ways. So first of all, you would have

0:26:48.280 --> 0:26:51.119
<v Speaker 1>to wonder how does it work this lay way, Like

0:26:51.400 --> 0:26:54.520
<v Speaker 1>why would vertical pupils be useful if you were an

0:26:54.560 --> 0:26:58.560
<v Speaker 1>ambush predator, especially as you were saying, an ambush predator

0:26:58.600 --> 0:27:02.280
<v Speaker 1>of low height, because height matters. So if you're you're

0:27:02.280 --> 0:27:05.320
<v Speaker 1>an active predator chasing down prey, you likely have round pupils,

0:27:05.400 --> 0:27:09.119
<v Speaker 1>or if you're an ambush predator that is taller, you

0:27:09.200 --> 0:27:12.960
<v Speaker 1>probably have round pupils. Vertical slits of what you're really

0:27:13.080 --> 0:27:15.680
<v Speaker 1>likely to see if you're a sit and wait, jump

0:27:15.680 --> 0:27:18.720
<v Speaker 1>out predator and you're close to the ground. So I

0:27:18.720 --> 0:27:21.480
<v Speaker 1>want to read a section from this paper, and there's

0:27:21.480 --> 0:27:23.720
<v Speaker 1>a couple of bits of terminology. To understand the quote

0:27:23.760 --> 0:27:27.679
<v Speaker 1>I'm about to read, it'll use the term stereopsis. Stereopsis

0:27:27.880 --> 0:27:32.360
<v Speaker 1>is depth perception that is created by comparing the difference

0:27:32.440 --> 0:27:35.879
<v Speaker 1>between what is seen by two different eyes focusing on

0:27:35.920 --> 0:27:39.159
<v Speaker 1>the same image. So we use stereopsis to uh to

0:27:39.280 --> 0:27:41.520
<v Speaker 1>judge depth when we when we look at an image

0:27:41.520 --> 0:27:44.400
<v Speaker 1>by the brain says, okay, we've got two different data

0:27:44.480 --> 0:27:46.840
<v Speaker 1>points of the eyes, and it compares them together and

0:27:46.920 --> 0:27:50.280
<v Speaker 1>gives you this three D image with depth. But then

0:27:50.320 --> 0:27:53.800
<v Speaker 1>the other term is defocus blur. This refers to the

0:27:53.880 --> 0:27:57.159
<v Speaker 1>blurry nous and objects that are either close or farther away,

0:27:57.400 --> 0:28:00.720
<v Speaker 1>closer farther away than you're focusing. So the authors of

0:28:00.720 --> 0:28:05.880
<v Speaker 1>this paper right quote, vertically elongated pupils create a stigmatic

0:28:06.040 --> 0:28:10.680
<v Speaker 1>depth of field, such that images of vertical contours nearer

0:28:10.800 --> 0:28:13.520
<v Speaker 1>or farther than the distance to which the eyes focused

0:28:13.760 --> 0:28:18.440
<v Speaker 1>are sharp, whereas images of horizontal contours at different distances

0:28:18.480 --> 0:28:22.440
<v Speaker 1>are blurred. This is advantageous for ambush predators to use

0:28:22.480 --> 0:28:27.480
<v Speaker 1>stereopsis to estimate distances of vertical contours and defocus blur

0:28:27.600 --> 0:28:32.040
<v Speaker 1>to estimate distances of horizontal contours. So, rob, if you'll

0:28:32.040 --> 0:28:34.160
<v Speaker 1>scroll down a bit in the notes here, I attached

0:28:34.160 --> 0:28:37.240
<v Speaker 1>a picture that they put in the paper to simulate

0:28:37.359 --> 0:28:40.440
<v Speaker 1>what it looks like to a creature that's gazing out

0:28:40.480 --> 0:28:44.520
<v Speaker 1>at the world with vertical slit pupils. Uh. And it's

0:28:44.560 --> 0:28:46.720
<v Speaker 1>a very interesting So they've they've got a picture with

0:28:46.800 --> 0:28:50.400
<v Speaker 1>a toy bird sitting on the ground, presumably a foot

0:28:50.480 --> 0:28:54.160
<v Speaker 1>or two ahead of where the camera is positioned, and

0:28:54.200 --> 0:28:57.000
<v Speaker 1>then there's some objects in the foreground in and the background.

0:28:57.520 --> 0:29:00.360
<v Speaker 1>And what you'll notice about this picture is that, um,

0:29:00.560 --> 0:29:03.720
<v Speaker 1>the bird is very much in tight focus, but then

0:29:03.760 --> 0:29:07.520
<v Speaker 1>for objects around it there is there is an uneven

0:29:07.640 --> 0:29:11.400
<v Speaker 1>amount of blurry nous in the vertical and horizontal directions.

0:29:11.480 --> 0:29:14.560
<v Speaker 1>So like there's a plant stalk that's poking right up

0:29:14.560 --> 0:29:18.240
<v Speaker 1>in the foreground, and its shape is fairly in focus

0:29:18.280 --> 0:29:21.400
<v Speaker 1>when you're looking at it height wise, you know, like

0:29:21.440 --> 0:29:24.080
<v Speaker 1>the stalk is is sort of sort of blurry but

0:29:24.160 --> 0:29:27.800
<v Speaker 1>sort of in focus. But things in the horizontal direction,

0:29:27.960 --> 0:29:30.880
<v Speaker 1>like the the top of the pot that the plant

0:29:30.920 --> 0:29:34.320
<v Speaker 1>is sitting in, are very blurry. And apparently it allows

0:29:34.360 --> 0:29:38.520
<v Speaker 1>these animals to use both the the stereopsis, the comparing

0:29:38.520 --> 0:29:40.920
<v Speaker 1>the two different eyes if the animal has two front

0:29:40.920 --> 0:29:45.480
<v Speaker 1>facing eyes, and the way that images are blurred when

0:29:45.480 --> 0:29:48.760
<v Speaker 1>they're at different levels of distance from the object in

0:29:48.840 --> 0:29:53.040
<v Speaker 1>focus to judge depth very well, so you can really

0:29:53.200 --> 0:29:56.000
<v Speaker 1>nail that bird when you jump. So sorry if that

0:29:56.040 --> 0:29:57.760
<v Speaker 1>was a little complicated, but it took me a while

0:29:57.800 --> 0:29:59.880
<v Speaker 1>to understand. I was trying to figure out, like why

0:30:00.080 --> 0:30:03.240
<v Speaker 1>the vertical slits actually help with the hunting, But yeah,

0:30:03.360 --> 0:30:05.680
<v Speaker 1>I think it makes sense if you especially if you

0:30:05.760 --> 0:30:08.000
<v Speaker 1>look up the picture, you can say like, oh, okay,

0:30:08.080 --> 0:30:10.200
<v Speaker 1>this is yeah, this is for an animal that is

0:30:10.240 --> 0:30:14.080
<v Speaker 1>precisely trying to target a jump at something and you've

0:30:14.080 --> 0:30:23.400
<v Speaker 1>got one shot pulling it off. But there was another

0:30:23.440 --> 0:30:25.680
<v Speaker 1>thing noted in this paper that I thought was really interesting,

0:30:25.760 --> 0:30:27.840
<v Speaker 1>and this was actually just in the introduction, but it

0:30:27.880 --> 0:30:31.640
<v Speaker 1>was about advantages of slit shaped pupils over round ones

0:30:31.680 --> 0:30:35.120
<v Speaker 1>in general. So we were just talking about vertical pupils

0:30:35.160 --> 0:30:37.600
<v Speaker 1>for for a load of the ground ambush predators, but

0:30:38.080 --> 0:30:42.160
<v Speaker 1>slit pupils in general can be advantageous because they allow

0:30:42.280 --> 0:30:45.960
<v Speaker 1>for much greater changes in the area of the pupil

0:30:46.480 --> 0:30:49.520
<v Speaker 1>and thus greater variation in the light conditions they can

0:30:49.560 --> 0:30:52.920
<v Speaker 1>adapt to. So you've got a human pupil. Just to

0:30:53.080 --> 0:30:56.760
<v Speaker 1>constrict a round human pupil like ours, you need that

0:30:56.920 --> 0:31:00.440
<v Speaker 1>ring shaped sphincter muscle that we talked about at h

0:31:00.640 --> 0:31:04.680
<v Speaker 1>in the last episode. But to close a slit pupil

0:31:04.880 --> 0:31:08.520
<v Speaker 1>uses two muscles that close the sides of the slit together.

0:31:09.200 --> 0:31:12.680
<v Speaker 1>And as a result of these morphological differences there there

0:31:12.760 --> 0:31:16.320
<v Speaker 1>is a different amount that you can increase or or

0:31:16.440 --> 0:31:19.600
<v Speaker 1>decrease the the area of the pupil and in the

0:31:19.600 --> 0:31:21.920
<v Speaker 1>amount of light that it can pull in. So, to

0:31:22.000 --> 0:31:25.000
<v Speaker 1>read from the paper quote, the vertical slit pupils of

0:31:25.040 --> 0:31:29.240
<v Speaker 1>the domestic cat and geck undergo area changes of a

0:31:29.360 --> 0:31:33.840
<v Speaker 1>hundred and thirty five and three hundred fold, respectively, whereas

0:31:33.920 --> 0:31:38.760
<v Speaker 1>human circular pupil changes by about fifteen fold. Species. Yeah,

0:31:38.840 --> 0:31:42.360
<v Speaker 1>species that are active in night and day need to

0:31:42.440 --> 0:31:46.320
<v Speaker 1>dilate sufficiently under dim conditions while constricting enough to prevent

0:31:46.440 --> 0:31:50.800
<v Speaker 1>dazzle in daylight. So a slit pupil provides the required

0:31:50.880 --> 0:31:54.480
<v Speaker 1>dynamic range. So this is why a slit pupil is good.

0:31:54.480 --> 0:31:57.000
<v Speaker 1>It's great for high dynamic range for an eye that

0:31:57.080 --> 0:32:00.239
<v Speaker 1>works great in both bright daylight and in pitched arc

0:32:01.280 --> 0:32:03.800
<v Speaker 1>And you know, I can't help but think with smaller

0:32:03.840 --> 0:32:06.360
<v Speaker 1>predators as well. I mean, these are generally going to

0:32:06.440 --> 0:32:10.560
<v Speaker 1>be creatures that are not only predator but prey as well.

0:32:10.600 --> 0:32:13.440
<v Speaker 1>So it's not like they can just hold up, uh,

0:32:13.480 --> 0:32:15.120
<v Speaker 1>you know, all day. I mean, they may try to

0:32:15.160 --> 0:32:17.040
<v Speaker 1>hold up all day, but they might need to play

0:32:17.080 --> 0:32:19.920
<v Speaker 1>the survival game during daylight as well, assuming they're not

0:32:19.960 --> 0:32:23.320
<v Speaker 1>actively hunting during the day as well of course, right right, So,

0:32:23.320 --> 0:32:27.040
<v Speaker 1>so yes, a slit pupil is great for for being

0:32:27.120 --> 0:32:30.720
<v Speaker 1>highly adaptable to whatever the light situation is. But the

0:32:30.760 --> 0:32:34.400
<v Speaker 1>directional orientation of the slit depends more on your ecological

0:32:34.520 --> 0:32:37.280
<v Speaker 1>niche like you were talking about earlier. So again, yeah,

0:32:37.280 --> 0:32:41.320
<v Speaker 1>the grazing herbivores like horses, they will have horizontal slits

0:32:41.360 --> 0:32:43.960
<v Speaker 1>to help them keep a panoramic view of the environment

0:32:44.040 --> 0:32:48.840
<v Speaker 1>and watch for movement or predators approaching. But another interesting

0:32:48.880 --> 0:32:52.960
<v Speaker 1>finding of the authors here, these pupil orientations for herbivores

0:32:53.000 --> 0:32:56.480
<v Speaker 1>only work if the animal keeps the pupil parallel to

0:32:56.520 --> 0:33:00.200
<v Speaker 1>the horizon, and grazing herbivores actually spend much of their

0:33:00.240 --> 0:33:03.880
<v Speaker 1>time with their heads bent down to the ground eating grass.

0:33:04.960 --> 0:33:07.720
<v Speaker 1>So what gives there? Well, the researchers looked into this

0:33:08.480 --> 0:33:11.520
<v Speaker 1>and they found that, in fact, when horses been down

0:33:11.520 --> 0:33:16.120
<v Speaker 1>to graze, they rotate their eyes within the sockets to

0:33:16.360 --> 0:33:21.040
<v Speaker 1>keep the pupils parallel to the horizon. And Martin Banks

0:33:21.040 --> 0:33:23.400
<v Speaker 1>in that NPR article he gives a quote pointing out

0:33:23.400 --> 0:33:25.520
<v Speaker 1>that this is weird because the eyes have to rotate

0:33:25.560 --> 0:33:27.960
<v Speaker 1>in opposite directions, you know, think about the eyes on

0:33:28.000 --> 0:33:31.920
<v Speaker 1>opposite sides. Uh. And apparently they couldn't find any references

0:33:31.920 --> 0:33:34.720
<v Speaker 1>to anybody ever writing about this before, which is funny

0:33:35.000 --> 0:33:38.960
<v Speaker 1>given how much time people spend around horses. But yeah, so,

0:33:39.040 --> 0:33:41.000
<v Speaker 1>so that's what horses do when they've been down to

0:33:41.080 --> 0:33:44.440
<v Speaker 1>the grass. Their eyes swivel in the sockets to maintain

0:33:44.440 --> 0:33:47.840
<v Speaker 1>the pupil slit as parallel to the horizon. Wow, this

0:33:47.920 --> 0:33:49.400
<v Speaker 1>is another one of the and I I know we've we've

0:33:49.400 --> 0:33:53.560
<v Speaker 1>talked about this before, and you know, imagining uh, alien

0:33:53.640 --> 0:33:56.600
<v Speaker 1>life forms and so forth, but also getting intigenous ideas

0:33:56.600 --> 0:33:59.640
<v Speaker 1>of consciousness, like how much of our our understanding of

0:33:59.640 --> 0:34:03.000
<v Speaker 1>ourselves in the world seems to come down to to

0:34:03.440 --> 0:34:06.280
<v Speaker 1>how we view the world and how we focus attention,

0:34:06.920 --> 0:34:09.520
<v Speaker 1>um and uh. And you have to try and put

0:34:09.560 --> 0:34:12.839
<v Speaker 1>yourself in the mindset of of a mind that is

0:34:12.960 --> 0:34:16.200
<v Speaker 1>that that perceives the world in this manner that you know,

0:34:16.239 --> 0:34:19.000
<v Speaker 1>that that has eyes that are always focused on the

0:34:19.040 --> 0:34:22.440
<v Speaker 1>horizon in order to get this panoramic view of of

0:34:22.480 --> 0:34:25.240
<v Speaker 1>all the potential threats that could be interfering with they're feeding.

0:34:25.600 --> 0:34:27.920
<v Speaker 1>One less funny note that was in that NPR coverage

0:34:27.920 --> 0:34:32.280
<v Speaker 1>of this paper was about depictions of dinosaurs in Jurassic

0:34:32.320 --> 0:34:34.960
<v Speaker 1>World and other movies. So you know, you've got this

0:34:35.320 --> 0:34:37.799
<v Speaker 1>some kind of giga predator dinosaur. It's just like the

0:34:37.880 --> 0:34:40.759
<v Speaker 1>ultimate what do they call it? In Jurassic World. It

0:34:40.840 --> 0:34:45.040
<v Speaker 1>was like the Killer Rex or so this is the

0:34:45.320 --> 0:34:49.080
<v Speaker 1>this is the Hannibal electro one Killamus maximus yeah, something

0:34:49.120 --> 0:34:51.719
<v Speaker 1>like that. Yeah, well, they talk about the temptation to

0:34:52.400 --> 0:34:56.520
<v Speaker 1>depict predators like this with with vertical slits for eyes,

0:34:56.560 --> 0:34:59.759
<v Speaker 1>because I think we correctly detect that as a predatory.

0:35:00.200 --> 0:35:02.440
<v Speaker 1>You look at the crocodile's eyes, it's got these creepy

0:35:02.520 --> 0:35:05.520
<v Speaker 1>vertical slits, and that makes sense because the crocodile is

0:35:05.560 --> 0:35:08.759
<v Speaker 1>an ambush predator that operates low to the ground. But

0:35:08.880 --> 0:35:12.239
<v Speaker 1>they say, actually, uh this, you know, the the Kilumus

0:35:12.239 --> 0:35:16.840
<v Speaker 1>maximus dinosaur is an active predator and it's very tall,

0:35:16.920 --> 0:35:20.879
<v Speaker 1>so it would probably have round pupils like ours. And

0:35:20.920 --> 0:35:23.320
<v Speaker 1>the funny thing is, you can't even use the frog excuse,

0:35:23.400 --> 0:35:26.920
<v Speaker 1>like oftentimes that is used to excuse sort of stuck

0:35:26.920 --> 0:35:29.640
<v Speaker 1>in the mud depictions of dinosaurs and the Drassic Park

0:35:29.719 --> 0:35:32.680
<v Speaker 1>traffic Jurassic World movies. They'll say, well, you have to

0:35:32.680 --> 0:35:36.239
<v Speaker 1>remember they also used frog DNA, So the fact that

0:35:36.280 --> 0:35:37.680
<v Speaker 1>they don't have feathers that has to do with the

0:35:37.680 --> 0:35:40.040
<v Speaker 1>frog DNA. But if it was the frog DNA, and

0:35:40.080 --> 0:35:42.840
<v Speaker 1>perhaps they would all have heart shaped pupils depending on

0:35:42.840 --> 0:35:45.279
<v Speaker 1>the type of frogs that we used, right, Yeah, And

0:35:45.480 --> 0:35:47.120
<v Speaker 1>that brings us back to the next thing, which is,

0:35:47.120 --> 0:35:50.400
<v Speaker 1>so we were talking about the orientations of slit shaped

0:35:50.440 --> 0:35:54.319
<v Speaker 1>pupils versus round pupils in terrestrial vertebrates. But when you

0:35:54.360 --> 0:35:57.200
<v Speaker 1>start looking at the eyes, there are the pupils of

0:35:57.280 --> 0:36:00.600
<v Speaker 1>animals that live in the water. He starts. Even weird shapes,

0:36:01.000 --> 0:36:03.640
<v Speaker 1>and dolphins and cuttle fish and all kinds of things

0:36:03.680 --> 0:36:10.000
<v Speaker 1>have these strangely shaped pupils. Yeah. The cuttlefish pupil especially

0:36:10.200 --> 0:36:12.719
<v Speaker 1>is very fascinating to look at. Definitely look up a

0:36:12.719 --> 0:36:15.759
<v Speaker 1>picture of it if you're you're not picturing it right now.

0:36:15.800 --> 0:36:19.319
<v Speaker 1>It looks like this wavy W. It looks kind of like,

0:36:20.400 --> 0:36:22.440
<v Speaker 1>you know, the face on the Pringles can is that

0:36:22.880 --> 0:36:26.719
<v Speaker 1>Mr Pringles, Dr Pringles, I can't remember, Doctor Pringles man,

0:36:28.680 --> 0:36:35.080
<v Speaker 1>which is that Governor Pringle's Governor Pringles, Senator Pringles, Yes Pringles.

0:36:36.000 --> 0:36:40.160
<v Speaker 1>He has a mustache and um under under certain light conditions.

0:36:40.520 --> 0:36:43.240
<v Speaker 1>The cuttlefish I looks like that mustache in my opinion.

0:36:43.760 --> 0:36:45.759
<v Speaker 1>But the interesting thing is that, yes it has. The

0:36:45.760 --> 0:36:49.359
<v Speaker 1>cuttlefish I has this signature W shape in bright light,

0:36:49.920 --> 0:36:54.239
<v Speaker 1>but it's actually circular in low light. Um. According to

0:36:54.800 --> 0:36:58.560
<v Speaker 1>the W shaped pupil in cuttlefish by a math at

0:36:58.600 --> 0:37:02.480
<v Speaker 1>All published in Vision re Search in the two main

0:37:02.600 --> 0:37:07.080
<v Speaker 1>theories um were that the shape is either for camouflage,

0:37:07.920 --> 0:37:10.280
<v Speaker 1>so it's just it has a weird pupil because it's

0:37:10.360 --> 0:37:13.560
<v Speaker 1>doing all sorts of strange things with its chromatic force

0:37:13.680 --> 0:37:16.600
<v Speaker 1>to you know, to change its UH its appearance, and

0:37:16.640 --> 0:37:18.600
<v Speaker 1>therefore it has you know, strange things going on in

0:37:18.680 --> 0:37:21.520
<v Speaker 1>his high as well, or that it has to do

0:37:21.560 --> 0:37:23.960
<v Speaker 1>with distance calculations. It's coming down to some of the

0:37:24.000 --> 0:37:28.000
<v Speaker 1>same UH factors that that we just discussed in terms

0:37:28.040 --> 0:37:33.000
<v Speaker 1>of vertical um in horizontal pupils. But in this case,

0:37:33.080 --> 0:37:35.959
<v Speaker 1>the researchers proposed that the W shaped pupil might aid

0:37:36.000 --> 0:37:39.799
<v Speaker 1>in balancing out the vertically uneven light field of its

0:37:39.880 --> 0:37:45.160
<v Speaker 1>natural habitat. So here's a quote from from that paper. Quote.

0:37:45.320 --> 0:37:48.720
<v Speaker 1>While an animal's retina can deal with a wide range

0:37:48.760 --> 0:37:53.480
<v Speaker 1>of light intensities in one scene, reducing this range would

0:37:53.520 --> 0:37:58.440
<v Speaker 1>limit the need for rapid local adaptation during vertical gaze shifts.

0:37:58.920 --> 0:38:02.640
<v Speaker 1>Since cuttlefish do not have an instant three sixty field

0:38:02.680 --> 0:38:06.600
<v Speaker 1>of view, they must rely on gaze shifts to provide

0:38:06.640 --> 0:38:10.240
<v Speaker 1>them with the complete view of the surrounding world. Okay,

0:38:10.239 --> 0:38:13.600
<v Speaker 1>so they have to move their eyes to look around them, right,

0:38:13.800 --> 0:38:15.640
<v Speaker 1>and you know, in this, we have to think about

0:38:16.320 --> 0:38:19.160
<v Speaker 1>light in the aquatic world, you know, where you know,

0:38:19.200 --> 0:38:22.640
<v Speaker 1>the the ever present darkness of the depths and then

0:38:22.760 --> 0:38:27.320
<v Speaker 1>the periodic light field realm of the the the upper depth.

0:38:27.680 --> 0:38:30.840
<v Speaker 1>And if you're something like cuttlefish, you're having to navigate both.

0:38:31.080 --> 0:38:32.799
<v Speaker 1>And it kind of comes down to some of the

0:38:32.800 --> 0:38:37.000
<v Speaker 1>ideas we're discussing with with with load of the ground predators.

0:38:37.000 --> 0:38:39.600
<v Speaker 1>You know, you have to sort of be a be

0:38:39.640 --> 0:38:42.799
<v Speaker 1>adaptable to both realms, but in this case, you need

0:38:42.840 --> 0:38:47.000
<v Speaker 1>to be able to uh to simultaneously deal with the

0:38:47.120 --> 0:38:50.880
<v Speaker 1>light in the darkness by the way, coming out of

0:38:50.880 --> 0:38:53.520
<v Speaker 1>the water for a second, the gecko pupil I was

0:38:53.560 --> 0:38:56.520
<v Speaker 1>reading about essentially as a vertical pupil aiding in a

0:38:56.560 --> 0:39:00.439
<v Speaker 1>nocturnal ambush predators lifestyle. But it does look really cool

0:39:00.520 --> 0:39:04.040
<v Speaker 1>and they are apparently really incredible hunting eyes according to

0:39:04.080 --> 0:39:07.120
<v Speaker 1>some of the articles that I looked at um. But

0:39:07.160 --> 0:39:10.360
<v Speaker 1>then oh, another aquatic eye of note is the dolphin

0:39:10.440 --> 0:39:14.560
<v Speaker 1>pupil um and it's it's interesting that while it resembles

0:39:14.600 --> 0:39:18.880
<v Speaker 1>a horseshoe or crescent, when it's fully dilated, it constricts

0:39:18.920 --> 0:39:23.440
<v Speaker 1>down to two tiny openings uh that are sometimes referred

0:39:23.440 --> 0:39:28.000
<v Speaker 1>to as a double pupil um. And this apparently comes

0:39:28.000 --> 0:39:30.240
<v Speaker 1>down to the fact that the the the pupil shape

0:39:30.400 --> 0:39:32.040
<v Speaker 1>with dolphins has to do with dolphins or noted for

0:39:32.120 --> 0:39:35.160
<v Speaker 1>having exceptional vision both in and out of the water. Uh,

0:39:35.200 --> 0:39:39.160
<v Speaker 1>they know, they're they're they're they're able to position their

0:39:39.200 --> 0:39:41.920
<v Speaker 1>bodies so that they're gazing out of the water and

0:39:42.239 --> 0:39:45.200
<v Speaker 1>they have great vision in that circumstance as well. But

0:39:45.480 --> 0:39:47.400
<v Speaker 1>I included a photograph here for you, Joe, and I

0:39:47.480 --> 0:39:50.319
<v Speaker 1>encourage listeners to look this up as well. Um, the

0:39:50.360 --> 0:39:53.800
<v Speaker 1>first picture shows the horseshoe pupil, and then the second

0:39:53.800 --> 0:39:58.080
<v Speaker 1>picture shows the double pupil when everything is fully constricted. Yeah,

0:39:58.120 --> 0:40:00.279
<v Speaker 1>it does look amazing though, if you do look up

0:40:00.320 --> 0:40:04.120
<v Speaker 1>scientific diagrams of the eye. I think what these are

0:40:04.520 --> 0:40:08.680
<v Speaker 1>explaining that's normally happening is like that the the sort

0:40:08.680 --> 0:40:12.960
<v Speaker 1>of horseshoe or or you shaped people when it constricts.

0:40:13.000 --> 0:40:15.520
<v Speaker 1>What it actually constricts down to is something that looks

0:40:15.600 --> 0:40:19.000
<v Speaker 1>kind of like two earbuds connected by a wire and

0:40:19.040 --> 0:40:22.880
<v Speaker 1>the wire is just very narrow. Yes. Yes, now some

0:40:22.960 --> 0:40:25.440
<v Speaker 1>of you might be wondering, Okay, you're talking about mythic

0:40:25.520 --> 0:40:28.359
<v Speaker 1>figures with strange eyes. And now we've we've talked about

0:40:28.360 --> 0:40:31.880
<v Speaker 1>a number of different real life organisms that have some

0:40:31.920 --> 0:40:35.560
<v Speaker 1>sort of interesting eyes going on. Uh. Is it possible

0:40:35.640 --> 0:40:39.440
<v Speaker 1>that that that the myth makers and the storytellers of

0:40:39.440 --> 0:40:43.080
<v Speaker 1>old were inspired by eyes they saw in nature? And

0:40:43.239 --> 0:40:46.520
<v Speaker 1>I didn't really find anybody talking about this, I mean

0:40:46.600 --> 0:40:49.160
<v Speaker 1>outside of Yes, if you're watching some sort of modern

0:40:49.160 --> 0:40:52.040
<v Speaker 1>show and reptile people show up and they have vertical

0:40:52.080 --> 0:40:55.719
<v Speaker 1>slits and their eyeballs, yes, obviously somebody decided let's give

0:40:55.760 --> 0:40:59.640
<v Speaker 1>them reptile eyes. Um. So again, if they're reptile people,

0:40:59.640 --> 0:41:01.640
<v Speaker 1>I mean, if they're like, I don't know, five six

0:41:01.640 --> 0:41:03.720
<v Speaker 1>ft tall or something, the should probably have round eyes.

0:41:04.280 --> 0:41:05.920
<v Speaker 1>What if they what if they crawl around on their

0:41:05.920 --> 0:41:08.640
<v Speaker 1>bellies all the time that's how they hunt? Okay, then

0:41:08.760 --> 0:41:12.960
<v Speaker 1>then yeah, vertical slits, go for it. But I was thinking, Okay,

0:41:13.000 --> 0:41:18.040
<v Speaker 1>the cuttlefish has this amazing looking I um, any possibility there? Well,

0:41:18.440 --> 0:41:22.520
<v Speaker 1>I mean the common or European cuttlefish can be found

0:41:22.560 --> 0:41:26.400
<v Speaker 1>in Irish waters, and cuttle fish shells or cuttlefish bones

0:41:26.440 --> 0:41:30.160
<v Speaker 1>were used as ornaments um by the Celts. According to D. J.

0:41:30.360 --> 0:41:34.920
<v Speaker 1>Conway in the book Celtic Magic, Ireland However, it's famously

0:41:34.960 --> 0:41:38.600
<v Speaker 1>led on reptile species, so I don't think gecks would

0:41:38.600 --> 0:41:41.720
<v Speaker 1>have had an impact on any literary motifs. And and ultimately,

0:41:41.760 --> 0:41:44.080
<v Speaker 1>I don't think anybody was pulling up any cuttle fish

0:41:44.120 --> 0:41:47.360
<v Speaker 1>and and checking out their their eyeballs either or you know,

0:41:47.400 --> 0:41:50.479
<v Speaker 1>I've I found nothing to suggest that, but my mind

0:41:50.520 --> 0:41:52.960
<v Speaker 1>went there, so I thought i'd mentioned it to everybody.

0:41:53.239 --> 0:41:54.879
<v Speaker 1>You know, I think this show is a safe place

0:41:54.920 --> 0:41:58.000
<v Speaker 1>to admit research dead ends. Sometimes we just got to

0:41:58.000 --> 0:42:00.600
<v Speaker 1>do that. Yeah, unless there's a paper out there I'm

0:42:00.600 --> 0:42:03.680
<v Speaker 1>missing and if so, as always, if there's something we've missed,

0:42:03.920 --> 0:42:06.200
<v Speaker 1>right in and let us know, we would love to

0:42:06.239 --> 0:42:09.160
<v Speaker 1>be corrected. Well, should we tighten the sphincter constrict the

0:42:09.160 --> 0:42:12.279
<v Speaker 1>pupil on this one? That's right, Uh, that's what what's

0:42:12.320 --> 0:42:14.200
<v Speaker 1>what we should do. We should limit the light coming

0:42:14.200 --> 0:42:17.000
<v Speaker 1>in at this point. Um, But we'd love to hear

0:42:17.000 --> 0:42:20.640
<v Speaker 1>from everyone out there. If there are particular mythic figures,

0:42:20.760 --> 0:42:26.960
<v Speaker 1>literary figures, pop culture examples of of multi pupil, multi irist,

0:42:27.120 --> 0:42:30.600
<v Speaker 1>multi lobed eyes right in and let us know about them.

0:42:30.600 --> 0:42:32.960
<v Speaker 1>Send some pictures if if they exist. We would love

0:42:32.960 --> 0:42:35.000
<v Speaker 1>to hear from you. Likewise, if there are other you know,

0:42:35.040 --> 0:42:37.560
<v Speaker 1>we we really only spend a little bit of time

0:42:37.600 --> 0:42:40.799
<v Speaker 1>here with the animal world. Uh, there's so many fascinating

0:42:40.840 --> 0:42:43.960
<v Speaker 1>animal eyes out there, So if there are examples that

0:42:44.040 --> 0:42:46.960
<v Speaker 1>you're particularly fond of, right in, let us know. Uh.

0:42:47.000 --> 0:42:49.319
<v Speaker 1>And then of course there are other areas of this

0:42:49.640 --> 0:42:51.719
<v Speaker 1>that we've just touched on in these two episodes that

0:42:51.719 --> 0:42:54.719
<v Speaker 1>we could easily come back and discuss more about, like oh,

0:42:54.880 --> 0:42:57.439
<v Speaker 1>the evil Eye as we were discussing like that could

0:42:57.440 --> 0:43:00.960
<v Speaker 1>be its own deep dive on the show, no doubt.

0:43:01.239 --> 0:43:02.960
<v Speaker 1>All right. In the meantime, if you would like to
