WEBVTT - From the Vault: The Three-Pupiled Eye, Part 2

0:00:05.760 --> 0:00:07.600
<v Speaker 1>Hey, you welcome to Stuff to Blow your Mind. My

0:00:07.680 --> 0:00:11.119
<v Speaker 1>name is Robert Lamb and I'm Joe McCormick. And it's Saturday,

0:00:11.160 --> 0:00:13.600
<v Speaker 1>which means we're going on down into the old vault

0:00:13.640 --> 0:00:16.560
<v Speaker 1>to pull out a classic episode of the show for you.

0:00:16.640 --> 0:00:19.600
<v Speaker 1>This one is from last year. This one is from

0:00:19.640 --> 0:00:23.360
<v Speaker 1>March thirty first, twenty twenty two, and it is the

0:00:23.520 --> 0:00:27.320
<v Speaker 1>Three Pupil Die Part two. This is the follow up

0:00:27.320 --> 0:00:31.680
<v Speaker 1>to the episode that aired last Saturday about about strange

0:00:31.760 --> 0:00:39.120
<v Speaker 1>pupils and irises in myth, legend and reality. Welcome to

0:00:39.159 --> 0:00:48.680
<v Speaker 1>Stuff to Blow Your Mind, a production of iHeartRadio. Hey,

0:00:48.840 --> 0:00:50.920
<v Speaker 1>welcome to Stuff to Blow your Mind. My name is

0:00:51.000 --> 0:00:54.520
<v Speaker 1>Robert Lamb and I'm Joe McCormick. In our last episode,

0:00:54.560 --> 0:00:59.760
<v Speaker 1>we discussed a common but enthralling literary motif in Irish mythology,

0:01:00.160 --> 0:01:03.680
<v Speaker 1>the triple and the sevenfold eye, three or seven pupils,

0:01:03.680 --> 0:01:07.560
<v Speaker 1>three or seven irises found in the eyes of beautiful heroes,

0:01:08.000 --> 0:01:13.080
<v Speaker 1>divine seers, destructive monsters. We also discussed the structure and

0:01:13.160 --> 0:01:16.360
<v Speaker 1>functionality of the human eye and the rare instances in

0:01:16.440 --> 0:01:21.280
<v Speaker 1>which we actually see double pupils in human eyes. In

0:01:21.319 --> 0:01:24.440
<v Speaker 1>this episode, we're going to explore more curious eyes from

0:01:24.480 --> 0:01:28.000
<v Speaker 1>the natural world, as well as more accounts of marvelous

0:01:28.040 --> 0:01:31.800
<v Speaker 1>eyes from ancient history and literature. But first a pop

0:01:31.840 --> 0:01:35.360
<v Speaker 1>culture update. At the end of last episode we were talking,

0:01:35.840 --> 0:01:40.640
<v Speaker 1>I spoke briefly about some double eyes that I remembered

0:01:40.680 --> 0:01:44.760
<v Speaker 1>from some movies, album covers, etc. Well, our good producer

0:01:44.840 --> 0:01:48.560
<v Speaker 1>Seth provided us with two additional examples of double eyes

0:01:48.600 --> 0:01:50.800
<v Speaker 1>and popular culture that we didn't think of last time.

0:01:51.400 --> 0:01:55.240
<v Speaker 1>Number one, the double irises and pupils of Aminet in

0:01:55.360 --> 0:01:58.880
<v Speaker 1>twenty seventeens. The Mummy. This is the Tom Cruise Mummy film.

0:01:58.880 --> 0:02:01.200
<v Speaker 1>Oh boy, did not see it, but I think this

0:02:01.320 --> 0:02:03.960
<v Speaker 1>is like the the titular Mummy, or at least one

0:02:03.960 --> 0:02:06.760
<v Speaker 1>of them. I think she is the Mummy in this film.

0:02:06.840 --> 0:02:08.919
<v Speaker 1>I'm okay, I haven't seen this one, not even on

0:02:08.960 --> 0:02:12.240
<v Speaker 1>an airplane, but I'm not opposed to it. I mean,

0:02:12.720 --> 0:02:15.520
<v Speaker 1>I've seen a lot of crummy mummy movies over the years,

0:02:15.560 --> 0:02:18.560
<v Speaker 1>and usually there's something interesting in them. Yeah, at least

0:02:18.600 --> 0:02:22.400
<v Speaker 1>sometimes you get an Arnold Foslou or something. Yeah. And

0:02:22.400 --> 0:02:24.720
<v Speaker 1>then the second example Seth brings up is the album

0:02:24.760 --> 0:02:31.000
<v Speaker 1>cover to Bubba by Haitian Canadian musician k Trenada featuring

0:02:31.040 --> 0:02:34.520
<v Speaker 1>the artist with otherworldly blue eyes that have double pupils,

0:02:34.639 --> 0:02:37.440
<v Speaker 1>double irises. I listened to a track from this album

0:02:37.480 --> 0:02:39.600
<v Speaker 1>while we were working on notes. It was good. I

0:02:39.600 --> 0:02:41.400
<v Speaker 1>haven't had a chance yet, but I do love the

0:02:41.560 --> 0:02:45.440
<v Speaker 1>album cover. It's pretty great now. One of the sources

0:02:45.480 --> 0:02:49.320
<v Speaker 1>that we mentioned in the last episode was the Evil

0:02:49.480 --> 0:02:53.160
<v Speaker 1>Eye in early Irish literature and law. This was published

0:02:53.200 --> 0:02:56.560
<v Speaker 1>in Celtica twenty four back in two thousand and three,

0:02:57.600 --> 0:03:01.160
<v Speaker 1>and this was by Jacqueline Borsch and the author of

0:03:01.200 --> 0:03:04.839
<v Speaker 1>Fergus Kelly is also cited on this paper because there's

0:03:04.840 --> 0:03:06.200
<v Speaker 1>like a part one in a part two, but I

0:03:06.200 --> 0:03:09.840
<v Speaker 1>believe we're we dealt with material from part one. Celtica,

0:03:09.919 --> 0:03:12.840
<v Speaker 1>the journal this is in is a scholarly journal for

0:03:12.919 --> 0:03:16.400
<v Speaker 1>Celtic studies out of the Dublin Institute for Advanced Studies.

0:03:17.240 --> 0:03:19.880
<v Speaker 1>So most of this deals of course with Irish law,

0:03:19.919 --> 0:03:26.400
<v Speaker 1>Irish traditions, Irish mythology, and despite the popularity of this

0:03:26.520 --> 0:03:31.240
<v Speaker 1>motif of the multiple pupils, multiple irises within the Irish tradition,

0:03:31.480 --> 0:03:35.000
<v Speaker 1>we also encounter discussions of this sort of thing in

0:03:35.120 --> 0:03:39.000
<v Speaker 1>other traditions as well, and shares a few of these

0:03:40.040 --> 0:03:42.960
<v Speaker 1>The first one comes to us from A Plenty of

0:03:42.960 --> 0:03:46.640
<v Speaker 1>The Elder and the Natural History. Plenty discusses individuals in

0:03:46.680 --> 0:03:50.560
<v Speaker 1>Africa said to possess quote, the power of fascination with

0:03:50.600 --> 0:03:53.560
<v Speaker 1>the eyes and can even kill those on whom they

0:03:53.600 --> 0:03:57.160
<v Speaker 1>fix their gaze for any length of time, more especially

0:03:57.200 --> 0:04:00.280
<v Speaker 1>if their look denotes anger. Now that's you're pretty basic

0:04:01.000 --> 0:04:04.960
<v Speaker 1>evil eye scenario right there. You encounter variations of this

0:04:05.840 --> 0:04:09.400
<v Speaker 1>throughout the world, based on the fact that, yes, you

0:04:09.440 --> 0:04:13.680
<v Speaker 1>can shoot somebody a really terrible look and you can

0:04:14.040 --> 0:04:17.039
<v Speaker 1>almost feel it. Of course, going back into the ancient world,

0:04:17.080 --> 0:04:19.640
<v Speaker 1>the belief was often that it was more than you know,

0:04:19.720 --> 0:04:22.400
<v Speaker 1>giving somebody the stink eye produced more than just a

0:04:22.440 --> 0:04:25.360
<v Speaker 1>bad feeling, that it could literally curse them or cause

0:04:25.440 --> 0:04:29.200
<v Speaker 1>them magical harm. Yes. But the neat thing here where

0:04:29.240 --> 0:04:31.160
<v Speaker 1>it ties into what we're talking about in these episodes

0:04:31.320 --> 0:04:35.120
<v Speaker 1>is Plenty goes on to connect this to multiple pupils quote.

0:04:35.400 --> 0:04:39.200
<v Speaker 1>A still more remarkable circumstance is the fact that these

0:04:39.240 --> 0:04:44.080
<v Speaker 1>persons have two pupils in each eye. Apollo Nides says

0:04:44.240 --> 0:04:47.680
<v Speaker 1>that there are certain females of this description in Scythia

0:04:47.760 --> 0:04:52.520
<v Speaker 1>who are known as the Bitha and Philarchus states that

0:04:52.600 --> 0:04:56.400
<v Speaker 1>a tribe of the theebe in Pontus, and many other

0:04:56.440 --> 0:04:59.320
<v Speaker 1>persons as well, have a double pupil in one eye

0:04:59.520 --> 0:05:02.320
<v Speaker 1>and in the other the figure of a horse. Double

0:05:02.400 --> 0:05:06.360
<v Speaker 1>pupil in one eye, the other the figure of a horse. Now,

0:05:06.400 --> 0:05:08.840
<v Speaker 1>with passages of this kind, we're often faced with the

0:05:08.920 --> 0:05:13.960
<v Speaker 1>question is this based on some distorted or exaggerated retelling

0:05:13.960 --> 0:05:17.640
<v Speaker 1>of something that somebody actually saw, or is it just

0:05:17.720 --> 0:05:22.200
<v Speaker 1>pure creative imagination or you know, tall tales, And it's

0:05:22.200 --> 0:05:25.120
<v Speaker 1>always interesting to wonder about the former, But ancient accounts

0:05:25.120 --> 0:05:28.400
<v Speaker 1>like Plenties are clearly full of the ladder, especially when

0:05:28.680 --> 0:05:31.599
<v Speaker 1>telling stories about peoples who live in far away parts

0:05:31.600 --> 0:05:34.560
<v Speaker 1>of the globe. You know, this section that we're quoting

0:05:34.640 --> 0:05:37.000
<v Speaker 1>from plenty is from I can't remember what it's called.

0:05:37.360 --> 0:05:39.120
<v Speaker 1>There's like one of his books is all about the

0:05:39.200 --> 0:05:41.880
<v Speaker 1>nations of the world, and it's just all these weird

0:05:41.960 --> 0:05:44.800
<v Speaker 1>stories of like here's a people who live somewhere far away,

0:05:44.839 --> 0:05:48.159
<v Speaker 1>and here's this strange thing they do or something that

0:05:48.200 --> 0:05:51.800
<v Speaker 1>they wear that would be fascinating to my readers. Like

0:05:51.839 --> 0:05:53.680
<v Speaker 1>there's one part where he talks about a tribe of

0:05:53.720 --> 0:05:56.880
<v Speaker 1>people somewhere who do not have heads and instead have

0:05:57.080 --> 0:06:01.040
<v Speaker 1>eyes in their breasts. So it need not be the

0:06:01.040 --> 0:06:05.359
<v Speaker 1>case that Plenty is necessarily here repeating a misunderstood or

0:06:05.440 --> 0:06:08.920
<v Speaker 1>exaggerated story about somebody who actually had something like polychoria

0:06:09.120 --> 0:06:12.480
<v Speaker 1>or some other unusual condition of the pupils. But of

0:06:12.480 --> 0:06:15.800
<v Speaker 1>course it is always possible. Yeah, it does make you wonder,

0:06:16.120 --> 0:06:19.039
<v Speaker 1>you know, to what extent would there be, like, you know,

0:06:19.120 --> 0:06:23.600
<v Speaker 1>some account of an individual with this rare condition, some

0:06:23.720 --> 0:06:26.280
<v Speaker 1>memory of this rare condition, and then it gets folded

0:06:26.320 --> 0:06:30.240
<v Speaker 1>into some of these traditions and beliefs at one point

0:06:30.320 --> 0:06:33.200
<v Speaker 1>or another in their long lives. Yes, though of course

0:06:33.240 --> 0:06:35.839
<v Speaker 1>it could again just be something somebody made up, like

0:06:35.839 --> 0:06:37.760
<v Speaker 1>the people who don't have heads and have eyes in

0:06:37.760 --> 0:06:41.039
<v Speaker 1>their breasts, right right, Like, we can dream up individuals

0:06:41.080 --> 0:06:44.479
<v Speaker 1>with like four arms, and it's pretty interesting and we

0:06:44.480 --> 0:06:47.039
<v Speaker 1>can draw all sorts of meaning from that, but it

0:06:47.080 --> 0:06:50.479
<v Speaker 1>doesn't mean that people with four arms ever actually existed,

0:06:50.920 --> 0:06:53.760
<v Speaker 1>you know, that there's any actual biological basis on which

0:06:53.800 --> 0:06:56.159
<v Speaker 1>that was based. Though. I do think it's really interesting

0:06:56.200 --> 0:06:58.280
<v Speaker 1>that he doesn't just say, Okay, they've got two pupils

0:06:58.320 --> 0:07:01.240
<v Speaker 1>in each eye, but that they've got two pupils in

0:07:01.360 --> 0:07:04.600
<v Speaker 1>one eye and in the other eye a horse. Yeah,

0:07:04.640 --> 0:07:07.799
<v Speaker 1>And like the first place my mind went was, Okay,

0:07:07.880 --> 0:07:10.320
<v Speaker 1>is it actually shaped like a horse a distortion that

0:07:10.440 --> 0:07:14.360
<v Speaker 1>is roughly horse shaped? Or is it? Does it mean

0:07:14.400 --> 0:07:16.720
<v Speaker 1>that this is like some sort of telephone game, you know,

0:07:16.760 --> 0:07:20.840
<v Speaker 1>translation game version of a horizontal pupil like one finds

0:07:20.840 --> 0:07:23.640
<v Speaker 1>in the eyeble horse. That's interesting, and that'll tie into

0:07:23.720 --> 0:07:25.960
<v Speaker 1>a scientific paper we're going to talk about in a bit.

0:07:26.880 --> 0:07:31.640
<v Speaker 1>I found an editor's footnote in the Bostock translation of Plenty,

0:07:31.720 --> 0:07:35.640
<v Speaker 1>which notes, quote, some of the commentators have supposed that

0:07:35.760 --> 0:07:38.640
<v Speaker 1>Plenty or Phi larcis from whom he borrows, because remember,

0:07:38.720 --> 0:07:41.840
<v Speaker 1>this isn't an original observation of Plenties, He's like copying

0:07:41.880 --> 0:07:44.840
<v Speaker 1>this from some other writing of this person named phi Larcus,

0:07:44.960 --> 0:07:49.400
<v Speaker 1>but Philarcus from whom he borrows. Whether they were misled

0:07:49.400 --> 0:07:53.880
<v Speaker 1>by the ambiguity of the Greek term eCos, which signifies

0:07:54.040 --> 0:07:58.760
<v Speaker 1>either a horse or a tremulous motion of the eye.

0:07:59.680 --> 0:08:02.160
<v Speaker 1>But even admitting this to be the case, the wonder

0:08:02.240 --> 0:08:05.120
<v Speaker 1>is scarcely diminished, for we have the double pupil in

0:08:05.240 --> 0:08:09.360
<v Speaker 1>one eye, while this supposed tremulous motion is confined to

0:08:09.400 --> 0:08:12.240
<v Speaker 1>the other. So so if Fostuck is correct there, it's

0:08:12.320 --> 0:08:14.640
<v Speaker 1>that this word had had a double meaning, and one

0:08:14.680 --> 0:08:17.040
<v Speaker 1>of them was like a you know, a quivering of

0:08:17.080 --> 0:08:19.000
<v Speaker 1>the eye. I guess I would assume that's like when

0:08:19.040 --> 0:08:22.880
<v Speaker 1>somebody's eye is twitching. But yeah, you wonder, well, why

0:08:22.920 --> 0:08:24.880
<v Speaker 1>why is it just that the other eye is twitching

0:08:24.960 --> 0:08:27.000
<v Speaker 1>when when the first eye has two pupils in it,

0:08:27.080 --> 0:08:30.040
<v Speaker 1>that's also strange, maybe not as strange as a horse.

0:08:30.840 --> 0:08:32.800
<v Speaker 1>I was. I was looking for answers on this as well,

0:08:32.840 --> 0:08:36.200
<v Speaker 1>and I ran across a nineteen eighteen paper titled of

0:08:36.240 --> 0:08:39.240
<v Speaker 1>the Papula duplex and Other Tokens of an Evil Eye

0:08:39.679 --> 0:08:47.080
<v Speaker 1>in the Light of Ophthalmology by Walton Brooks McDaniel, And

0:08:47.240 --> 0:08:51.120
<v Speaker 1>according to Brooks, here one doctor Kirby Flower Smith, a

0:08:51.240 --> 0:08:54.920
<v Speaker 1>professor of Latin and at John Hopkins University, who had

0:08:55.040 --> 0:08:58.480
<v Speaker 1>I looked VI had died in nineteen eighteen, interpreted the

0:08:58.520 --> 0:09:02.200
<v Speaker 1>Plenty passage as having some sort of connection to the

0:09:02.280 --> 0:09:04.560
<v Speaker 1>idea that the affliction of the eye was caused by

0:09:04.679 --> 0:09:10.760
<v Speaker 1>quote a horse shaped demon, horsehead masked demon. Yeah. McDaniel

0:09:10.800 --> 0:09:13.880
<v Speaker 1>also begins to discuss the the idea that if you know,

0:09:13.920 --> 0:09:16.920
<v Speaker 1>if you look into another eye, you know certainly with

0:09:17.120 --> 0:09:19.240
<v Speaker 1>the right lighting and so forth, you look into another

0:09:19.240 --> 0:09:22.240
<v Speaker 1>person's eye, you can see your own reflection. And so

0:09:22.600 --> 0:09:28.160
<v Speaker 1>McDaniel mentions that in some traditions that individual you see

0:09:28.240 --> 0:09:31.160
<v Speaker 1>in the eye is interpreted, you know, not as yourself,

0:09:31.480 --> 0:09:34.600
<v Speaker 1>but as the signifier of the soul, and that there

0:09:34.600 --> 0:09:37.600
<v Speaker 1>are even some traditions where if the individual looks in

0:09:37.640 --> 0:09:42.600
<v Speaker 1>some way inverted, that is because of witchcraft. And in

0:09:42.640 --> 0:09:45.360
<v Speaker 1>this this this is one of those weird situations where

0:09:45.480 --> 0:09:49.200
<v Speaker 1>then McDaniel mentioned something else that leads me back to

0:09:49.240 --> 0:09:52.120
<v Speaker 1>a source that I'm very familiar with, and yet I

0:09:52.160 --> 0:09:56.640
<v Speaker 1>totally blinked on this particular detail, or or maybe I'd

0:09:56.640 --> 0:09:59.560
<v Speaker 1>never read this one particular tale, but he ends up

0:09:59.559 --> 0:10:04.040
<v Speaker 1>referring back to Strange Tales from a Chinese Studio by

0:10:04.080 --> 0:10:06.800
<v Speaker 1>Poosh song Ling. That's a show, favorite, folks. Should we

0:10:06.960 --> 0:10:09.480
<v Speaker 1>do we have a Strange Sales from a Chinese studio? Buzzer?

0:10:10.840 --> 0:10:12.800
<v Speaker 1>I doubt we do, but at any rate, it's it's

0:10:12.840 --> 0:10:14.480
<v Speaker 1>it's a book that I really enjoy. This is a

0:10:14.559 --> 0:10:19.680
<v Speaker 1>Ching Dynasty collection of stories that Pous song Ling collected

0:10:19.760 --> 0:10:22.440
<v Speaker 1>and retells, and you know there's a lot that's that's

0:10:22.480 --> 0:10:26.920
<v Speaker 1>lost in translation. Out of Mandarin. But but there's still

0:10:27.080 --> 0:10:32.400
<v Speaker 1>remarkable fun, sometimes funny, and sometimes it's just very strange. Uh.

0:10:32.440 --> 0:10:34.840
<v Speaker 1>Sometimes it's it's you know, it's all about what they

0:10:34.880 --> 0:10:37.000
<v Speaker 1>would have meant to the people who read them. But

0:10:37.320 --> 0:10:40.600
<v Speaker 1>they're a lot of fun. There's a Penguin edition of

0:10:40.679 --> 0:10:44.280
<v Speaker 1>it translation that I've I read again and again over

0:10:44.320 --> 0:10:47.200
<v Speaker 1>the years, and yet I completely blanked on this one story.

0:10:47.720 --> 0:10:51.079
<v Speaker 1>It's called Talking Pupils. I think maybe the reason that

0:10:51.160 --> 0:10:54.480
<v Speaker 1>I haven't read this one recently is sometimes i'll read

0:10:54.520 --> 0:10:57.160
<v Speaker 1>these to my son and I'll sort of glance at them,

0:10:57.160 --> 0:10:58.880
<v Speaker 1>and if it looks like there's something that might be

0:10:58.920 --> 0:11:01.320
<v Speaker 1>scandalous in it, or you know, a little dirty, then

0:11:01.360 --> 0:11:04.320
<v Speaker 1>I'll skip over the tale. There aren't many, but occasionally

0:11:04.360 --> 0:11:07.360
<v Speaker 1>there's one like that. So anyway, this story Talking Pupils

0:11:07.360 --> 0:11:10.600
<v Speaker 1>concerns the tale of one Feng Dong quote, a gentleman

0:11:10.640 --> 0:11:13.440
<v Speaker 1>of considerable accomplishments while at the same time having a

0:11:13.480 --> 0:11:19.040
<v Speaker 1>reputation as an unprincipled libertine. Oh yeah, so clearly that's

0:11:19.080 --> 0:11:21.360
<v Speaker 1>why I might have skipped over this in recent years. Anyway,

0:11:21.760 --> 0:11:24.760
<v Speaker 1>So Fang was this is how the story goes. Fang

0:11:24.840 --> 0:11:27.040
<v Speaker 1>is strolling the countryside and he happens on a fine

0:11:27.080 --> 0:11:30.880
<v Speaker 1>carriage on the road. One of the female attendants to

0:11:30.920 --> 0:11:33.680
<v Speaker 1>the carriage is quite fetching, so he moves in for

0:11:33.720 --> 0:11:36.240
<v Speaker 1>a closer look. But as he does so, he's able

0:11:36.240 --> 0:11:38.760
<v Speaker 1>to peek between the curtains of the carriage itself and

0:11:38.800 --> 0:11:42.719
<v Speaker 1>he sees a beautiful young woman within, and he's captivated.

0:11:43.040 --> 0:11:45.640
<v Speaker 1>The female attendant is having none of this, though, and

0:11:45.679 --> 0:11:49.360
<v Speaker 1>she verbally shames him, you know, calls him a you know,

0:11:49.400 --> 0:11:53.440
<v Speaker 1>a weirdo and a snooper. And not only does she

0:11:53.520 --> 0:11:56.319
<v Speaker 1>verbally shame him, she reaches down grabs him dust out

0:11:56.320 --> 0:11:59.199
<v Speaker 1>of the road and throws it in Fang's face. Oh,

0:11:59.320 --> 0:12:02.600
<v Speaker 1>dirty fighter. Yeah, but you know, he had it coming.

0:12:02.640 --> 0:12:05.160
<v Speaker 1>He was up to no good and he gets punished

0:12:05.160 --> 0:12:07.920
<v Speaker 1>for it. So he's he's initially he's trying to get

0:12:07.920 --> 0:12:10.839
<v Speaker 1>the dust out of his eyes. The carriage carries on.

0:12:10.920 --> 0:12:14.160
<v Speaker 1>When he is able to see again, you know, struggling,

0:12:14.400 --> 0:12:17.120
<v Speaker 1>the carriage is completely done. It's you know, it's vanished

0:12:17.120 --> 0:12:20.280
<v Speaker 1>around the bend or whatever. So he has heads on home,

0:12:20.320 --> 0:12:22.640
<v Speaker 1>but his eyes continue to bother him, so he seeks

0:12:22.640 --> 0:12:25.960
<v Speaker 1>some help. A friend looks into his eyes, and this

0:12:26.040 --> 0:12:28.440
<v Speaker 1>friend says, yeah, there's a visible film over each of

0:12:28.480 --> 0:12:33.199
<v Speaker 1>your eyeballs, and meanwhile, tears won't stop flowing. In time,

0:12:33.280 --> 0:12:37.320
<v Speaker 1>the film thickens and a spiral what is described as

0:12:37.360 --> 0:12:42.000
<v Speaker 1>a spiral shaped protuberance begins growing from his right eye,

0:12:42.480 --> 0:12:47.559
<v Speaker 1>resisting all manner of treatment. Eventually he's completely blind, and

0:12:47.600 --> 0:12:51.079
<v Speaker 1>you know he's he's distraught over this. But he hears

0:12:51.120 --> 0:12:54.240
<v Speaker 1>about a Buddhist sutra known as the Sutra of Light,

0:12:54.640 --> 0:12:57.160
<v Speaker 1>and it's said to be able to heal eye ailments

0:12:57.240 --> 0:13:00.000
<v Speaker 1>or ailments of this sort. So he gets a side

0:13:00.280 --> 0:13:03.080
<v Speaker 1>friend to read it to him, and he learns it

0:13:03.120 --> 0:13:05.400
<v Speaker 1>by heart, and he recites it over and over again,

0:13:05.600 --> 0:13:08.320
<v Speaker 1>and after a while it gives him solace. You know,

0:13:08.360 --> 0:13:10.480
<v Speaker 1>he feels a little better. His side is not back.

0:13:11.080 --> 0:13:14.840
<v Speaker 1>But then one day he begins to hear voices, two voices,

0:13:15.000 --> 0:13:18.040
<v Speaker 1>one from each of his eyeballs. Oh, I love this.

0:13:18.160 --> 0:13:20.840
<v Speaker 1>The eyeballs are talking, both of them. Well, as it

0:13:20.840 --> 0:13:24.120
<v Speaker 1>turns out, not the eyeballs but things within the eyeballs.

0:13:24.160 --> 0:13:27.679
<v Speaker 1>There's one voice within each eyeball, and they start talking

0:13:27.720 --> 0:13:29.400
<v Speaker 1>to each other, and they're talking about how dark it

0:13:29.440 --> 0:13:31.960
<v Speaker 1>is in their homes and how they'd really like to

0:13:32.120 --> 0:13:34.280
<v Speaker 1>just get outside and go for a stroll. And then

0:13:34.280 --> 0:13:38.199
<v Speaker 1>so pusong Ling says quote, then he felt a slight

0:13:38.240 --> 0:13:41.719
<v Speaker 1>irritation in both nostrils, as if two little creatures were

0:13:41.760 --> 0:13:44.640
<v Speaker 1>wriggling down his nose. After a while, he felt the

0:13:44.640 --> 0:13:47.479
<v Speaker 1>creatures return and make their way back up his nostrils

0:13:47.679 --> 0:13:51.880
<v Speaker 1>and into the eye sockets. Again, this is anatomically correct because,

0:13:51.960 --> 0:13:55.800
<v Speaker 1>as we know, the tear ducks that drain tears away

0:13:55.880 --> 0:13:59.240
<v Speaker 1>from the eyes drain into the nasal cavity, which is

0:13:59.280 --> 0:14:03.480
<v Speaker 1>why your nose when you cry. Oh very good. So

0:14:04.200 --> 0:14:06.360
<v Speaker 1>what does Feing do at this point, Well, he gets

0:14:06.360 --> 0:14:08.320
<v Speaker 1>his wife to take him to the old garden, and

0:14:08.360 --> 0:14:10.480
<v Speaker 1>he has her observe him in the garden to see

0:14:10.480 --> 0:14:12.840
<v Speaker 1>if anything like this happens again. Maybe the garden will

0:14:13.080 --> 0:14:16.360
<v Speaker 1>coax whatever it is out of his eyeballs. And this

0:14:16.440 --> 0:14:19.000
<v Speaker 1>is what happens. Quote. It was not long before she

0:14:19.080 --> 0:14:22.640
<v Speaker 1>saw two little mannekins, neither of them any larger than

0:14:22.680 --> 0:14:26.000
<v Speaker 1>a bean, emerged from his nose and fly buzzing out

0:14:26.000 --> 0:14:28.480
<v Speaker 1>of the door. They were soon well out of sight,

0:14:28.920 --> 0:14:31.840
<v Speaker 1>but we're back again in next to no time, flying

0:14:31.880 --> 0:14:35.160
<v Speaker 1>together up onto his face and in at his nostrils.

0:14:35.200 --> 0:14:38.240
<v Speaker 1>Like a pair of homing bees or ants. So is

0:14:38.280 --> 0:14:42.240
<v Speaker 1>he getting relief when they fly away? I don't think so. No. Oh,

0:14:42.720 --> 0:14:45.440
<v Speaker 1>it's just it happens, and he doesn't know what this

0:14:45.520 --> 0:14:49.080
<v Speaker 1>is about, so it keeps happening. It happens again each

0:14:49.120 --> 0:14:51.800
<v Speaker 1>day for three days, and finally one of the voices

0:14:51.880 --> 0:14:55.400
<v Speaker 1>complains that the tunnel that they're using to get out

0:14:55.440 --> 0:14:58.760
<v Speaker 1>of the eyeball is a bit round about and there's

0:14:58.760 --> 0:15:01.680
<v Speaker 1>got to be a better way. It's time that they

0:15:01.760 --> 0:15:04.960
<v Speaker 1>make some sort of proper doorway. So I'm going to

0:15:05.000 --> 0:15:07.640
<v Speaker 1>read the rest of this year that it really gets

0:15:07.640 --> 0:15:10.400
<v Speaker 1>to the juicy part. I'm just I'm filled with dread.

0:15:10.440 --> 0:15:12.640
<v Speaker 1>It's not a good idea when the tenants in your

0:15:12.680 --> 0:15:17.120
<v Speaker 1>eyeballs decided to start renovating on their own. Yeah, so

0:15:17.960 --> 0:15:20.080
<v Speaker 1>that is how it goes. The wall on my side

0:15:20.160 --> 0:15:22.800
<v Speaker 1>is very thick, replied the right eye. It won't be easy.

0:15:23.320 --> 0:15:26.000
<v Speaker 1>I'll try to make an opening on my side, said

0:15:26.040 --> 0:15:29.960
<v Speaker 1>the left eye. Then we can share my door. Presently,

0:15:30.000 --> 0:15:33.240
<v Speaker 1>Fang thought he felt a scratching and a splitting in

0:15:33.320 --> 0:15:36.000
<v Speaker 1>his left eye socket, and an instant later he could

0:15:36.040 --> 0:15:38.920
<v Speaker 1>see he could see everything around him with absolute clarity.

0:15:38.960 --> 0:15:41.920
<v Speaker 1>Beside himself with a delight. He promptly informed his wife,

0:15:42.000 --> 0:15:44.800
<v Speaker 1>who inspected his eyes afresh and found that in the

0:15:44.880 --> 0:15:48.400
<v Speaker 1>left eye a minute aperture had appeared in the film,

0:15:48.440 --> 0:15:51.560
<v Speaker 1>a hole no larger than a cracked peppercorn, through which

0:15:51.640 --> 0:15:55.720
<v Speaker 1>gleamed the black globe of a pupil. By the next morning,

0:15:55.720 --> 0:15:58.920
<v Speaker 1>the film in the left eye had disappeared altogether. But

0:15:59.000 --> 0:16:01.680
<v Speaker 1>the strangest thing of all was that, on careful inspection,

0:16:01.720 --> 0:16:05.000
<v Speaker 1>there were now two pupils visible in that eye, and

0:16:05.080 --> 0:16:09.360
<v Speaker 1>the right eye was still obscured by its spiral shaped growth. Apparently,

0:16:09.440 --> 0:16:13.400
<v Speaker 1>both of the two eye mannequins his talking pupils had

0:16:13.440 --> 0:16:17.040
<v Speaker 1>now taken up residence in the left eye. So although

0:16:17.120 --> 0:16:19.920
<v Speaker 1>Fang was still blind in one eye, he could see

0:16:19.960 --> 0:16:22.600
<v Speaker 1>better with his one good eye than he had ever

0:16:22.640 --> 0:16:25.560
<v Speaker 1>done with two. From that day fourth, he was a

0:16:25.600 --> 0:16:29.600
<v Speaker 1>great deal more circumspect in his behavior and acquired unimpeccable

0:16:29.640 --> 0:16:33.240
<v Speaker 1>reputation in the district. Okay, so no more creeping on

0:16:33.320 --> 0:16:36.080
<v Speaker 1>ladies and carriages. Right, he learned his lesson, He was

0:16:36.360 --> 0:16:40.160
<v Speaker 1>punished for his creepy behavior, and now he's back and

0:16:40.480 --> 0:16:42.680
<v Speaker 1>ready to be a good citizen with one eye that

0:16:42.760 --> 0:16:46.880
<v Speaker 1>can see better than two, right, because two pupils. Now

0:16:46.880 --> 0:16:49.480
<v Speaker 1>that this again is from the Penguin Classics edition. It's

0:16:49.520 --> 0:16:53.280
<v Speaker 1>a John Minford translation, and this was super interesting as well.

0:16:53.320 --> 0:16:57.760
<v Speaker 1>Minford shares this in the notes pupils. The traditional Chinese

0:16:57.760 --> 0:17:02.640
<v Speaker 1>expression for pupil, tong wren, means literally man in the

0:17:02.680 --> 0:17:06.359
<v Speaker 1>pupil from the reflection of oneself that one sees in

0:17:06.400 --> 0:17:09.760
<v Speaker 1>the eye of another. Wow. Yeah, that was that was

0:17:09.800 --> 0:17:11.560
<v Speaker 1>really that. I was really impressed by that. And I

0:17:11.600 --> 0:17:13.800
<v Speaker 1>was talking to my wife about it because I was

0:17:13.840 --> 0:17:15.800
<v Speaker 1>looking around a little bit after this and I saw

0:17:15.840 --> 0:17:19.639
<v Speaker 1>an article about photography and about being able to zoom

0:17:19.640 --> 0:17:22.320
<v Speaker 1>in on the eye of an individual in a modern

0:17:22.320 --> 0:17:27.200
<v Speaker 1>photograph and see the reflection potentially of the photographer and

0:17:27.440 --> 0:17:31.680
<v Speaker 1>oh yeah, because of the high resolution, I guess, yeah, yeah.

0:17:31.720 --> 0:17:33.960
<v Speaker 1>And I was asking my wife about this, and she

0:17:34.080 --> 0:17:37.240
<v Speaker 1>pointed out that one thing that photographers can do is

0:17:37.280 --> 0:17:40.000
<v Speaker 1>you can pull up, say a headshot that another photographer

0:17:40.080 --> 0:17:42.760
<v Speaker 1>is done. You can zoom in on the eye and

0:17:42.840 --> 0:17:46.840
<v Speaker 1>you can see what their lighting setup is. So I

0:17:46.880 --> 0:17:49.200
<v Speaker 1>was impressed by that as well. Oh, I'm impressed. That's

0:17:49.200 --> 0:17:51.800
<v Speaker 1>a real James Bond level trick. I do not know

0:17:51.840 --> 0:17:54.359
<v Speaker 1>what to make of the spiral growth though I looked

0:17:54.359 --> 0:17:57.080
<v Speaker 1>around briefly on that and I was not able to

0:17:57.119 --> 0:18:02.080
<v Speaker 1>find any answers that seemed fencing. I have no expertise

0:18:02.200 --> 0:18:11.040
<v Speaker 1>on spiral growths from eyes. All right, I want to

0:18:11.040 --> 0:18:13.479
<v Speaker 1>go back to Borsch for just a minute here, because

0:18:14.280 --> 0:18:16.560
<v Speaker 1>she has a couple of other examples that she brings up.

0:18:17.080 --> 0:18:22.879
<v Speaker 1>One apparently tolomeos Chinos. This would have been a figure

0:18:22.960 --> 0:18:27.720
<v Speaker 1>from the late first early second century. CE once described

0:18:27.760 --> 0:18:31.439
<v Speaker 1>a beautiful woman as being quote with a double pupil. Okay,

0:18:31.480 --> 0:18:34.360
<v Speaker 1>And in the last episode we talked about some legends

0:18:34.800 --> 0:18:38.720
<v Speaker 1>in which a character with multiple pupils this was assumed

0:18:38.720 --> 0:18:41.159
<v Speaker 1>to be a marker of beauty. Right, So this is

0:18:41.160 --> 0:18:43.639
<v Speaker 1>interesting because it seems to suggest that this is not

0:18:43.720 --> 0:18:48.840
<v Speaker 1>just isolated within Irish literary traditions, that perhaps somewhere else

0:18:48.880 --> 0:18:51.600
<v Speaker 1>in the world there was this idea that double pupil

0:18:51.680 --> 0:18:54.679
<v Speaker 1>equals beauty. And I mean, who am I to say

0:18:54.720 --> 0:18:57.440
<v Speaker 1>it's not beautiful? You know, it's not like you look

0:18:57.440 --> 0:19:01.360
<v Speaker 1>at images of actual double pupil situations and you're not

0:19:01.800 --> 0:19:04.000
<v Speaker 1>hortified by them or anything, no more so than if

0:19:04.000 --> 0:19:06.920
<v Speaker 1>you look at a super close up of any human

0:19:06.920 --> 0:19:11.600
<v Speaker 1>Eyeball also mentions that ovid portrays a woman with double

0:19:11.640 --> 0:19:15.480
<v Speaker 1>pupils having the evil eye at one point, so tying

0:19:15.520 --> 0:19:19.040
<v Speaker 1>back into the evil eye tradition. But anyway, Bors concludes

0:19:19.160 --> 0:19:22.200
<v Speaker 1>quote to conclude this section, Both angry eyes and eyes

0:19:22.200 --> 0:19:25.480
<v Speaker 1>with multiple pupils have been connected with the concept of

0:19:25.480 --> 0:19:29.600
<v Speaker 1>the evil eye, there is no strict identity between the phenomena.

0:19:29.800 --> 0:19:33.080
<v Speaker 1>Multiple pupils can also be a sign of beauty, sharp sight,

0:19:33.440 --> 0:19:36.679
<v Speaker 1>and clairvoyance. Okay, so we're not really converging on a

0:19:36.800 --> 0:19:40.359
<v Speaker 1>unity of theme here. If you're in an Irish legend

0:19:40.440 --> 0:19:42.560
<v Speaker 1>or myth and you have a character with multiple pupils

0:19:42.560 --> 0:19:45.840
<v Speaker 1>in one eye, it seems they could either be somebody

0:19:45.920 --> 0:19:48.720
<v Speaker 1>who has a lot of insight, somebody who can see

0:19:48.840 --> 0:19:51.679
<v Speaker 1>very far away, somebody who can see the future, somebody

0:19:51.720 --> 0:19:55.560
<v Speaker 1>who is beautiful, or somebody who is monstrous or can

0:19:55.640 --> 0:19:59.200
<v Speaker 1>do curses. And there is this idea too that it's

0:19:59.320 --> 0:20:02.040
<v Speaker 1>it's part of like the supernatural body, that when you

0:20:02.119 --> 0:20:06.639
<v Speaker 1>have some sort of a demigod figure, it's the human body.

0:20:07.240 --> 0:20:10.000
<v Speaker 1>It's almost like it mutates with the divinity within it

0:20:10.359 --> 0:20:13.600
<v Speaker 1>like the human The normal human body cannot contain this

0:20:13.720 --> 0:20:17.240
<v Speaker 1>level of power and therefore, extra things are going to happen,

0:20:17.320 --> 0:20:20.640
<v Speaker 1>you know, extra pupils, extra fingers, that sort of thing.

0:20:21.680 --> 0:20:25.240
<v Speaker 1>And this ties directly into another example I found, and

0:20:25.320 --> 0:20:29.399
<v Speaker 1>this one comes from Chinese traditions as well. This is

0:20:29.440 --> 0:20:33.760
<v Speaker 1>from the nineteen sixty seven book Chinese Civilization and Bureaucracy,

0:20:34.320 --> 0:20:39.280
<v Speaker 1>Variations on a Theme by Hungarian born French senologist Eten

0:20:39.440 --> 0:20:45.240
<v Speaker 1>Balahs working with working from another source as well, Essay

0:20:45.320 --> 0:20:48.840
<v Speaker 1>on the Extinction of the Soul by Faun Shin, a

0:20:48.960 --> 0:20:53.440
<v Speaker 1>Chinese philosopher and writer who lived four fifty through five

0:20:53.560 --> 0:20:57.919
<v Speaker 1>fifteen CE. The subject here, as far as eyes are concerned,

0:20:58.400 --> 0:21:02.560
<v Speaker 1>is one of the legendary sage rulers of antiquity in China.

0:21:02.600 --> 0:21:05.680
<v Speaker 1>This would concern a time during the third millennium BC.

0:21:06.520 --> 0:21:09.520
<v Speaker 1>And so the structure of this paper seems to concern

0:21:09.680 --> 0:21:12.680
<v Speaker 1>like questions and answers. And so first we have this question.

0:21:13.320 --> 0:21:15.639
<v Speaker 1>The body of the sage is similar to the body

0:21:15.680 --> 0:21:18.160
<v Speaker 1>of ordinary men. Yet there is a difference by which

0:21:18.160 --> 0:21:21.480
<v Speaker 1>the sage is distinguished from ordinary men. From this, it

0:21:21.480 --> 0:21:25.440
<v Speaker 1>can be inferred that body and soul are different. Answer

0:21:26.000 --> 0:21:30.000
<v Speaker 1>not at all. Pure gold glitters and unwashed gold does

0:21:30.040 --> 0:21:33.520
<v Speaker 1>not pure gold. That glitters surely cannot be made of

0:21:33.560 --> 0:21:37.760
<v Speaker 1>the same unglittering material as that of unwashed gold. How

0:21:37.840 --> 0:21:40.639
<v Speaker 1>much less, then, can the soul of a sage be

0:21:40.840 --> 0:21:44.800
<v Speaker 1>lodged in a vessel such as the ordinary man. Nor

0:21:44.840 --> 0:21:47.400
<v Speaker 1>would it be possible for the soul of an ordinary

0:21:47.440 --> 0:21:50.760
<v Speaker 1>man to dwell in the body of a sage. Therefore,

0:21:50.880 --> 0:21:55.360
<v Speaker 1>fengg Sum is depicted as having eyebrows of eight colors,

0:21:55.840 --> 0:22:00.640
<v Speaker 1>and zong Huo's eyes with double pupils, signon as having

0:22:00.640 --> 0:22:03.960
<v Speaker 1>the face of a dragon, and tie how the mouth

0:22:04.000 --> 0:22:07.560
<v Speaker 1>of a horse, all of which are outward bodily signs

0:22:07.600 --> 0:22:11.640
<v Speaker 1>of their exceptional nature. All the seven openings were found

0:22:11.680 --> 0:22:14.600
<v Speaker 1>in the heart of pie Con. The gall bladder of

0:22:14.720 --> 0:22:17.760
<v Speaker 1>poe U was as big as a fist, which shows

0:22:17.800 --> 0:22:21.199
<v Speaker 1>that their inner organs were unusual. Thus we know that

0:22:21.320 --> 0:22:24.480
<v Speaker 1>certain parts of the bodies of sages are quite out

0:22:24.480 --> 0:22:27.560
<v Speaker 1>of the ordinary, and that sages are not only superior

0:22:27.600 --> 0:22:32.159
<v Speaker 1>to ordinary human beings, but also surpass all other creatures

0:22:32.200 --> 0:22:37.920
<v Speaker 1>in bodily form. That's just science. I love this passage

0:22:37.960 --> 0:22:40.240
<v Speaker 1>so much. I mean, I love that it's basically an

0:22:40.240 --> 0:22:45.480
<v Speaker 1>autopsy of supernatural sages, of determining how they're they're but

0:22:45.680 --> 0:22:48.160
<v Speaker 1>like you can imagine this scene in a movie. Oh yeah,

0:22:48.200 --> 0:22:50.679
<v Speaker 1>this is beautiful, the gall bladder as big as a fist,

0:22:51.600 --> 0:22:54.639
<v Speaker 1>showing that the inner organs are unusual. This is great,

0:22:54.680 --> 0:22:57.320
<v Speaker 1>and you know, and this is this is not a

0:22:57.359 --> 0:23:00.840
<v Speaker 1>totally unique view of the body of the holy person

0:23:00.960 --> 0:23:03.760
<v Speaker 1>or the saint. I mean, you know, there are tons

0:23:03.760 --> 0:23:07.119
<v Speaker 1>of traditions all around the world, including like the idea

0:23:07.200 --> 0:23:10.199
<v Speaker 1>that certain types of saints or holy people, because of

0:23:10.240 --> 0:23:14.520
<v Speaker 1>their spiritual nature, their bodies would be found to be say, incorruptible,

0:23:14.600 --> 0:23:18.320
<v Speaker 1>like they don't rot the way most spoties do. Yeah. So,

0:23:18.560 --> 0:23:21.000
<v Speaker 1>but Balais adds some notes on this and points out

0:23:21.000 --> 0:23:24.280
<v Speaker 1>that the legends about the eyebrows of eight colors and

0:23:24.400 --> 0:23:27.560
<v Speaker 1>the eyes with double pupils He's come from Mahan times

0:23:27.600 --> 0:23:30.600
<v Speaker 1>and are contained in a number of different works. So

0:23:30.680 --> 0:23:36.199
<v Speaker 1>yet another example of of of exceptional eyes in the

0:23:36.280 --> 0:23:40.679
<v Speaker 1>bodies of exceptional you know, heroic mythic individuals. Now, in

0:23:40.720 --> 0:23:43.120
<v Speaker 1>the last episode, we talked a bit about human eye

0:23:43.160 --> 0:23:47.560
<v Speaker 1>anatomy and some medical literature on polychoria, or the condition

0:23:47.600 --> 0:23:50.720
<v Speaker 1>of having multiple pupils within the same eye. But I

0:23:50.760 --> 0:23:52.680
<v Speaker 1>thought in this episode it would be a good idea

0:23:52.720 --> 0:23:56.440
<v Speaker 1>to turn to pupils of the animal kingdom more broadly,

0:23:56.520 --> 0:23:59.520
<v Speaker 1>because there's a lot we can learn about the function

0:23:59.640 --> 0:24:03.560
<v Speaker 1>of pupils by looking at the pupils of non human animals.

0:24:03.920 --> 0:24:07.320
<v Speaker 1>That's right. I mean, just consider the vast diversity we

0:24:07.400 --> 0:24:10.679
<v Speaker 1>have in the animal world, and I mean even just

0:24:10.760 --> 0:24:13.760
<v Speaker 1>dealing with the vertebrate world, it's pretty remarkable, not even

0:24:13.800 --> 0:24:16.960
<v Speaker 1>getting into compound eyes of flies and so forth. But

0:24:17.800 --> 0:24:22.440
<v Speaker 1>consider humans. We have round pupils. House cats have vertical slits,

0:24:22.960 --> 0:24:28.399
<v Speaker 1>Tigers have round pupils, Goats and horses horizontal. Dolphins have crescents,

0:24:28.880 --> 0:24:34.960
<v Speaker 1>cuttlefish have w shaped pupils, some frogs have heart shaped pupils,

0:24:35.000 --> 0:24:38.600
<v Speaker 1>and geckos have these sort of what looked like pinholes

0:24:38.720 --> 0:24:41.360
<v Speaker 1>arranged in a vertical line. I always love a good

0:24:41.400 --> 0:24:45.400
<v Speaker 1>crocodile pupil. Oh, yes, tend to be rather vertical. Yeah,

0:24:45.480 --> 0:24:47.879
<v Speaker 1>it's and it's also it's a window into the crocodile soul.

0:24:48.160 --> 0:24:52.080
<v Speaker 1>But seeing all this different diversity does raise some questions

0:24:52.160 --> 0:24:55.080
<v Speaker 1>because you think, okay, well, you know, the bodies of

0:24:55.200 --> 0:24:59.040
<v Speaker 1>animals are shaped by their environment. You know, that's what

0:24:59.080 --> 0:25:02.240
<v Speaker 1>evolution does. It tends to give you the equipment that

0:25:02.440 --> 0:25:04.680
<v Speaker 1>best helps you do whatever you need to do within

0:25:04.720 --> 0:25:09.560
<v Speaker 1>your ecological niche. So why do different animals have different pupils?

0:25:09.280 --> 0:25:13.520
<v Speaker 1>How to differently shaped or sized pupils help an animal

0:25:13.600 --> 0:25:17.280
<v Speaker 1>adapt to how it's supposed to survive in the world. Yeah.

0:25:17.320 --> 0:25:20.560
<v Speaker 1>According to Martin Banks, the vision scientist at the University

0:25:20.600 --> 0:25:24.280
<v Speaker 1>of California that cited in a twenty fifteen NPR story,

0:25:24.359 --> 0:25:27.000
<v Speaker 1>eye shapes of the animal world hint at differences in

0:25:27.000 --> 0:25:31.000
<v Speaker 1>our lifestyles. Land animals of sufficient height tend to have

0:25:31.119 --> 0:25:34.920
<v Speaker 1>round pupils. Thus you have big cats that have round pupils.

0:25:35.160 --> 0:25:40.240
<v Speaker 1>Meanwhile your small house cat cat has vertical pupils. Verticals

0:25:40.280 --> 0:25:43.919
<v Speaker 1>are more the domain, it seems, of smaller ambush predators,

0:25:43.960 --> 0:25:48.120
<v Speaker 1>giving them an excellent ability at judging distances, of which,

0:25:48.119 --> 0:25:49.880
<v Speaker 1>of course, is going to be super important when you're

0:25:49.880 --> 0:25:54.359
<v Speaker 1>pouncing out of the shadows and trying to capture like

0:25:54.400 --> 0:25:58.359
<v Speaker 1>a small rodent or your owner's foot. Horizontal pupils, on

0:25:58.400 --> 0:26:00.680
<v Speaker 1>the other hand, are widely under stood as a means

0:26:00.680 --> 0:26:03.960
<v Speaker 1>of keeping a wider swath of the surroundings in sight

0:26:04.359 --> 0:26:08.560
<v Speaker 1>while you're grazing, and an expanded field of view. So

0:26:08.600 --> 0:26:11.280
<v Speaker 1>you can think of this as the panoramic potential prey

0:26:11.720 --> 0:26:14.640
<v Speaker 1>view of the world, right, So I was actually looking

0:26:14.680 --> 0:26:18.280
<v Speaker 1>into this. The paper that Banks is connected with is

0:26:18.320 --> 0:26:21.400
<v Speaker 1>one that was published in twenty fifteen in Science Advances,

0:26:21.880 --> 0:26:26.120
<v Speaker 1>and it's by Martin Banks, William Sprague, urg And Schmall,

0:26:26.480 --> 0:26:30.119
<v Speaker 1>Jared Parnell, and Gordon Love and it's called why do

0:26:30.240 --> 0:26:34.080
<v Speaker 1>animal eyes have pupils of different shapes? And what you

0:26:34.119 --> 0:26:37.160
<v Speaker 1>say is correct. They looked into this question and they found, yeah,

0:26:37.280 --> 0:26:41.080
<v Speaker 1>there are some very strong correlations between how an animal

0:26:41.200 --> 0:26:44.440
<v Speaker 1>survives and what shape its pupils are, at least among

0:26:44.720 --> 0:26:48.560
<v Speaker 1>land vertebrates. And so you tend to have, like you're saying,

0:26:48.600 --> 0:26:54.800
<v Speaker 1>horizontal pupils if you are a herbivore, whereas ambush predators

0:26:54.840 --> 0:26:56.760
<v Speaker 1>predators that sit around and wait for their prey, they

0:26:56.760 --> 0:27:00.080
<v Speaker 1>tend to have vertical slits, especially if they're active of

0:27:00.119 --> 0:27:05.280
<v Speaker 1>it in both daytime and nighttime. And meanwhile, active predators,

0:27:05.359 --> 0:27:09.119
<v Speaker 1>predators that hunt and chase down their prey instead of

0:27:09.119 --> 0:27:12.679
<v Speaker 1>sitting and waiting, they are more likely to have round

0:27:13.200 --> 0:27:16.359
<v Speaker 1>or circular pupils. And this is not a coincidence. The

0:27:16.400 --> 0:27:20.400
<v Speaker 1>author has found some pretty good reasons why the pupils

0:27:20.400 --> 0:27:23.119
<v Speaker 1>would be allotted in these ways. So first of all,

0:27:23.440 --> 0:27:25.760
<v Speaker 1>you would have to wonder how does it work this

0:27:25.840 --> 0:27:29.680
<v Speaker 1>lay way, Like why would vertical pupils be useful if

0:27:29.720 --> 0:27:33.320
<v Speaker 1>you are an ambush predator, especially as you were saying,

0:27:33.320 --> 0:27:36.800
<v Speaker 1>an ambush predator of low height, because height matters. So

0:27:37.240 --> 0:27:40.120
<v Speaker 1>if you're an active predator chasing down prey, you likely

0:27:40.119 --> 0:27:42.919
<v Speaker 1>have round pupils, or if you're an ambush predator that

0:27:43.160 --> 0:27:47.960
<v Speaker 1>is taller, you probably have round pupils vertical slits of

0:27:48.040 --> 0:27:50.440
<v Speaker 1>what you're really likely to see if you're a sit

0:27:50.520 --> 0:27:53.399
<v Speaker 1>and wait, jump out predator and you're close to the ground.

0:27:54.080 --> 0:27:56.359
<v Speaker 1>So I want to read a section from this paper,

0:27:56.680 --> 0:27:59.000
<v Speaker 1>and there's a couple bits of terminology. To understand the

0:27:59.080 --> 0:28:02.440
<v Speaker 1>quote I'm about to read, it'll use the term stereopsis.

0:28:02.480 --> 0:28:07.480
<v Speaker 1>Stereopsis is depth perception that is created by comparing the

0:28:07.520 --> 0:28:11.400
<v Speaker 1>difference between what is seen by two different eyes focusing

0:28:11.400 --> 0:28:15.240
<v Speaker 1>on the same image. So we use stereopsis to judge

0:28:15.280 --> 0:28:18.680
<v Speaker 1>depth when we look at an image by the brain says, okay,

0:28:18.720 --> 0:28:21.040
<v Speaker 1>we've got two different data points of the eyes, and

0:28:21.119 --> 0:28:23.639
<v Speaker 1>it compares them together and gives you this three D

0:28:24.160 --> 0:28:28.000
<v Speaker 1>image with depth. But then the other term is defocus blur,

0:28:28.560 --> 0:28:31.400
<v Speaker 1>This refers to the blurriness and objects that are either

0:28:31.480 --> 0:28:34.920
<v Speaker 1>close or farther away, closer or farther away than you're focusing.

0:28:35.520 --> 0:28:39.360
<v Speaker 1>So the authors of this paper right quote, vertically elongated

0:28:39.440 --> 0:28:43.760
<v Speaker 1>pupils create astigmatic depth of field, such that images of

0:28:43.960 --> 0:28:48.080
<v Speaker 1>vertical contours nearer or farther than the distance to which

0:28:48.160 --> 0:28:52.960
<v Speaker 1>the eyes focused are sharp, whereas images of horizontal contours

0:28:52.960 --> 0:28:57.120
<v Speaker 1>at different distances are blurred. This is advantageous for ambush

0:28:57.160 --> 0:29:01.560
<v Speaker 1>predators to use stereopsis to estimate distance says of vertical contours,

0:29:01.880 --> 0:29:06.720
<v Speaker 1>and defocus blur to estimate distances of horizontal contours. So

0:29:06.840 --> 0:29:09.200
<v Speaker 1>rob if you'll scroll down a bit in the notes here,

0:29:09.240 --> 0:29:11.960
<v Speaker 1>I attached a picture that they put in the paper

0:29:12.000 --> 0:29:15.440
<v Speaker 1>to simulate what it looks like to a creature that's

0:29:15.480 --> 0:29:19.840
<v Speaker 1>gazing out at the world with vertical slit pupils, and

0:29:19.960 --> 0:29:22.360
<v Speaker 1>it's a very interesting So they've got a picture with

0:29:22.400 --> 0:29:26.040
<v Speaker 1>a toy bird sitting on the ground, presumably a foot

0:29:26.080 --> 0:29:29.760
<v Speaker 1>or two ahead of where the camera is positioned, and

0:29:29.800 --> 0:29:32.640
<v Speaker 1>then there's some objects in the foreground in in the background,

0:29:33.080 --> 0:29:36.200
<v Speaker 1>and what you'll notice about this picture is that the

0:29:36.720 --> 0:29:39.440
<v Speaker 1>bird is very much in tight focus, but then for

0:29:39.560 --> 0:29:43.640
<v Speaker 1>objects around it there is there is an uneven amount

0:29:43.640 --> 0:29:47.479
<v Speaker 1>of blurriness in the vertical and horizontal directions. So like

0:29:47.760 --> 0:29:50.360
<v Speaker 1>there's a plant stalk that's poking right up in the

0:29:50.400 --> 0:29:54.240
<v Speaker 1>foreground and its shape is fairly in focus when you're

0:29:54.280 --> 0:29:57.600
<v Speaker 1>looking at it height wise, you know, like the stalk

0:29:57.720 --> 0:30:00.920
<v Speaker 1>is sort of sort of blurry but sort of in focus.

0:30:00.920 --> 0:30:05.200
<v Speaker 1>But things in the horizontal direction, like the top of

0:30:05.240 --> 0:30:08.600
<v Speaker 1>the pot that the plant is sitting in, are very blurry.

0:30:08.880 --> 0:30:13.280
<v Speaker 1>And apparently it allows these animals to use both the stereopsis,

0:30:13.360 --> 0:30:15.960
<v Speaker 1>the comparing the two different eyes if the animal has

0:30:16.000 --> 0:30:20.160
<v Speaker 1>two front facing eyes, and the way that images are

0:30:20.320 --> 0:30:23.800
<v Speaker 1>blurred when they're at different levels of distance from the

0:30:23.840 --> 0:30:28.240
<v Speaker 1>object in focus to judge depth very well. So you

0:30:28.240 --> 0:30:31.440
<v Speaker 1>can really nail that bird when you jump. So sorry

0:30:31.440 --> 0:30:33.120
<v Speaker 1>if that was a little complicated, but it took me

0:30:33.200 --> 0:30:35.240
<v Speaker 1>while to understand. I was trying to figure out, like

0:30:35.280 --> 0:30:38.840
<v Speaker 1>why the vertical slits actually help with the hunting. But yeah,

0:30:39.000 --> 0:30:41.320
<v Speaker 1>I think it makes sense if you especially if you

0:30:41.360 --> 0:30:43.680
<v Speaker 1>look up the picture, you can say like, oh, okay,

0:30:43.680 --> 0:30:45.840
<v Speaker 1>this is yeah, this is for an animal that is

0:30:45.880 --> 0:30:49.480
<v Speaker 1>precisely trying to target a jump at something. Yeah, and

0:30:49.520 --> 0:30:58.720
<v Speaker 1>you've got one shot pulling it off. But there was

0:30:58.720 --> 0:31:00.640
<v Speaker 1>another thing noted in this pain that I thought was

0:31:00.680 --> 0:31:03.160
<v Speaker 1>really interesting, and this was actually just in the introduction,

0:31:03.240 --> 0:31:06.600
<v Speaker 1>but it was about advantages of slit shaped pupils over

0:31:06.720 --> 0:31:08.960
<v Speaker 1>round ones in general. So we were just talking about

0:31:09.680 --> 0:31:13.120
<v Speaker 1>vertical pupils for a load of the ground ambush predators.

0:31:13.120 --> 0:31:17.360
<v Speaker 1>But slit pupils in general can be advantageous because they

0:31:17.440 --> 0:31:21.160
<v Speaker 1>allow for much greater changes in the area of the

0:31:21.200 --> 0:31:25.040
<v Speaker 1>pupil and thus greater variation in the light conditions they

0:31:25.040 --> 0:31:28.200
<v Speaker 1>can adapt to. So you've got a human pupil. To

0:31:28.680 --> 0:31:32.400
<v Speaker 1>constrict a round human pupil like ours, you need that

0:31:32.560 --> 0:31:35.800
<v Speaker 1>ring shaped sphincter muscle that we talked about at length

0:31:36.280 --> 0:31:40.320
<v Speaker 1>in the last episode. But to close a slit pupil,

0:31:40.360 --> 0:31:43.160
<v Speaker 1>it uses two muscles that close the sides of the

0:31:43.240 --> 0:31:47.120
<v Speaker 1>slit together. And as a result of these morphological differences,

0:31:47.640 --> 0:31:52.040
<v Speaker 1>there is a different amount that you can increase or

0:31:52.080 --> 0:31:55.640
<v Speaker 1>decrease the area of the pupil and the amount of

0:31:55.680 --> 0:31:58.080
<v Speaker 1>light that it can pull in. So, to read from

0:31:58.080 --> 0:32:01.320
<v Speaker 1>the paper quote, the vertical at pupils of the domestic

0:32:01.360 --> 0:32:05.479
<v Speaker 1>cat and gecko undergo area changes of one hundred and

0:32:05.520 --> 0:32:10.760
<v Speaker 1>thirty five and three hundredfold, respectively, whereas human circular pupil

0:32:10.880 --> 0:32:15.760
<v Speaker 1>changes by about fifteenfold. Yeah, species that are active in

0:32:15.920 --> 0:32:20.320
<v Speaker 1>night and day need to dilate sufficiently under dim conditions

0:32:20.320 --> 0:32:23.880
<v Speaker 1>while constricting enough to prevent dazzle in daylight. So a

0:32:24.000 --> 0:32:28.800
<v Speaker 1>slit pupil provides the required dynamic range. So this is

0:32:28.800 --> 0:32:30.920
<v Speaker 1>why a slit pupil is good. It's great for high

0:32:31.040 --> 0:32:33.680
<v Speaker 1>dynamic range for an eye that works great in both

0:32:33.800 --> 0:32:37.960
<v Speaker 1>bright daylight and in pitch dark. And you know, I

0:32:37.960 --> 0:32:41.040
<v Speaker 1>can't help but think with smaller predators as well. I mean,

0:32:41.040 --> 0:32:43.640
<v Speaker 1>these are generally going to be creatures that are not

0:32:43.760 --> 0:32:46.760
<v Speaker 1>only predator but prey as well. So it's not like

0:32:46.800 --> 0:32:49.959
<v Speaker 1>they can just hold up, you know, all day. I mean,

0:32:50.160 --> 0:32:51.719
<v Speaker 1>they may try to hold up all day, but they

0:32:51.800 --> 0:32:54.600
<v Speaker 1>might need to play the survival game during daylight as well,

0:32:54.840 --> 0:32:57.280
<v Speaker 1>assuming they're not actively hunting during the day as well

0:32:57.320 --> 0:33:00.560
<v Speaker 1>of course, right right, So, yes, a slit pupil is

0:33:00.600 --> 0:33:05.960
<v Speaker 1>great for being highly adaptable to whatever the light situation is,

0:33:06.040 --> 0:33:09.200
<v Speaker 1>But the directional orientation of the slit depends more on

0:33:09.240 --> 0:33:12.880
<v Speaker 1>your ecological niche like you were talking about earlier. So again, yeah,

0:33:12.880 --> 0:33:16.920
<v Speaker 1>the grazing herbivores, like horses, they will have horizontal slits

0:33:16.960 --> 0:33:19.600
<v Speaker 1>to help them keep a panoramic view of the environment

0:33:19.640 --> 0:33:24.440
<v Speaker 1>and watch for movement or predators approaching. But another interesting

0:33:24.520 --> 0:33:28.600
<v Speaker 1>finding of the authors here, these pupil orientations for herbivores

0:33:28.640 --> 0:33:32.080
<v Speaker 1>only work if the animal keeps the pupil parallel to

0:33:32.160 --> 0:33:35.800
<v Speaker 1>the horizon, and grazing herbivores actually spend much of their

0:33:35.840 --> 0:33:39.480
<v Speaker 1>time with their heads bent down to the ground eating grass.

0:33:40.560 --> 0:33:43.320
<v Speaker 1>So what gives there? Well, the researchers looked into this

0:33:44.040 --> 0:33:47.120
<v Speaker 1>and they found that, in fact, when horses bind down

0:33:47.160 --> 0:33:51.760
<v Speaker 1>to graze, they rotate their eyes within the sockets to

0:33:52.000 --> 0:33:56.640
<v Speaker 1>keep the pupils parallel to the horizon. And Martin Banks

0:33:56.680 --> 0:33:59.000
<v Speaker 1>in that NPR article he gives a quote pointing out

0:33:59.040 --> 0:34:01.160
<v Speaker 1>that this is weird because the eyes have to rotate

0:34:01.200 --> 0:34:03.600
<v Speaker 1>in opposite directions, you know, think about the eyes on

0:34:03.640 --> 0:34:07.000
<v Speaker 1>opposite side. So yeah, and apparently they couldn't find any

0:34:07.040 --> 0:34:09.920
<v Speaker 1>references to anybody ever writing about this before, which is

0:34:10.040 --> 0:34:14.320
<v Speaker 1>funny given how much time people spend around horses. But yeah,

0:34:14.400 --> 0:34:16.640
<v Speaker 1>so that's what horses do when they've been down to

0:34:16.680 --> 0:34:20.040
<v Speaker 1>the grass. Their eyes swivel in the sockets to maintain

0:34:20.080 --> 0:34:23.480
<v Speaker 1>the pupil slit as parallel to the horizon. Wow, this

0:34:23.560 --> 0:34:25.040
<v Speaker 1>is another one of the I don't know, we've we've

0:34:25.040 --> 0:34:29.480
<v Speaker 1>talked about this before, and you know, imagining alien life

0:34:29.480 --> 0:34:32.200
<v Speaker 1>forms and so forth, but also getting into just ideas

0:34:32.200 --> 0:34:35.319
<v Speaker 1>of consciousness, like how much of our our understanding of

0:34:35.320 --> 0:34:39.319
<v Speaker 1>ourselves in the world seems to come down to how

0:34:39.400 --> 0:34:42.680
<v Speaker 1>we view the world and how we focus attention um

0:34:43.320 --> 0:34:46.280
<v Speaker 1>and yet to try and put yourself in the mindset

0:34:46.440 --> 0:34:49.799
<v Speaker 1>of a mind that is that perceives the world in

0:34:49.880 --> 0:34:52.880
<v Speaker 1>this manner that you know, that that has eyes that

0:34:52.920 --> 0:34:56.520
<v Speaker 1>are always focused on the horizon in order to get

0:34:56.520 --> 0:34:59.480
<v Speaker 1>this panoramic view of all the potential threats that could

0:34:59.520 --> 0:35:02.239
<v Speaker 1>be interfered with they're feeding one lass. Funny note that

0:35:02.280 --> 0:35:05.080
<v Speaker 1>was in that NPR coverage of this paper was about

0:35:05.400 --> 0:35:09.839
<v Speaker 1>depictions of dinosaurs in Jurassic World and other movies. So

0:35:09.920 --> 0:35:12.800
<v Speaker 1>you know, you've got this some kind of giga predator dinosaur.

0:35:12.840 --> 0:35:15.319
<v Speaker 1>It's just like the ultimate what do they call it

0:35:15.320 --> 0:35:19.279
<v Speaker 1>in Jurassic World. It was like the Killer Rex or

0:35:19.320 --> 0:35:22.759
<v Speaker 1>so this is the this is the Hannibal electro one, Yeah,

0:35:22.920 --> 0:35:26.279
<v Speaker 1>Kilamus maximus, yeah, something like that. Yeah. Well, they talk

0:35:26.320 --> 0:35:31.240
<v Speaker 1>about the temptation to depict predators like this with vertical

0:35:31.280 --> 0:35:34.520
<v Speaker 1>slits for eyes, because I think we correctly detect that

0:35:34.600 --> 0:35:37.160
<v Speaker 1>as a predatory trait. You look at a crocodile's eyes,

0:35:37.200 --> 0:35:39.879
<v Speaker 1>it's got these creepy vertical slits, and that makes sense

0:35:39.920 --> 0:35:43.160
<v Speaker 1>because a crocodile is an ambush predator that operates low

0:35:43.200 --> 0:35:46.600
<v Speaker 1>to the ground. But they say, actually this, you know,

0:35:46.640 --> 0:35:51.839
<v Speaker 1>the Kilamus maximus dinosaur is an active predator and it's

0:35:51.920 --> 0:35:55.000
<v Speaker 1>very tall, so it would probably have round pupils like ours.

0:35:56.239 --> 0:35:58.160
<v Speaker 1>And the funny thing is, you can't even use the

0:35:58.200 --> 0:36:02.040
<v Speaker 1>frog excuse, like oftentimes that is used to excuse sort

0:36:02.040 --> 0:36:04.200
<v Speaker 1>of stuck in the mud depictions of dinosaurs in the

0:36:04.280 --> 0:36:08.040
<v Speaker 1>Durassic Park Traffic Jurassic World movies. They'll say, well, you

0:36:08.080 --> 0:36:11.520
<v Speaker 1>have to remember they also used frog DNA, So the

0:36:11.560 --> 0:36:13.160
<v Speaker 1>fact that they don't have feathers that has to do

0:36:13.160 --> 0:36:15.560
<v Speaker 1>with the frog DNA. But it was the frog DNA,

0:36:15.600 --> 0:36:18.360
<v Speaker 1>then perhaps they would all have heart shaped pupils depending

0:36:18.400 --> 0:36:20.640
<v Speaker 1>on the type of frogs that were used. Right, Yeah,

0:36:20.680 --> 0:36:22.719
<v Speaker 1>And that brings us back to the next thing, which is,

0:36:22.719 --> 0:36:26.040
<v Speaker 1>so we were talking about the orientations of slit shaped

0:36:26.040 --> 0:36:29.960
<v Speaker 1>pupils versus round pupils in terrestrial vertebrates. But when you

0:36:30.000 --> 0:36:32.840
<v Speaker 1>start looking at the eyes there are the pupils of

0:36:32.920 --> 0:36:35.719
<v Speaker 1>animals that live in the water. You starts even weirder

0:36:35.800 --> 0:36:39.319
<v Speaker 1>shapes in dolphins and cuttlefish and all kinds of things

0:36:39.320 --> 0:36:45.640
<v Speaker 1>have these strangely shaped pupils. Yeah. The cuttlefish pupil especially

0:36:45.840 --> 0:36:48.360
<v Speaker 1>is very fascinating to look at. Definitely look up a

0:36:48.360 --> 0:36:51.399
<v Speaker 1>picture of it if you're not picturing it right now.

0:36:51.440 --> 0:36:54.960
<v Speaker 1>It looks like this WAVYW. It looks kind of like,

0:36:56.040 --> 0:36:58.000
<v Speaker 1>you know, the face on the Pringles can. Is that

0:36:58.440 --> 0:37:02.359
<v Speaker 1>mister Pringles, Doctor Pringles, I can't remember, doctor Pringles. Man,

0:37:04.320 --> 0:37:08.959
<v Speaker 1>which is that Governor Pringles? Governor Pringles, yes, Senator Pringles, Yes,

0:37:09.280 --> 0:37:13.400
<v Speaker 1>we have Walter K. Pringles. He has a mustache and

0:37:13.760 --> 0:37:17.279
<v Speaker 1>um under under certain light conditions, the cuttlefish eye looks

0:37:17.320 --> 0:37:20.319
<v Speaker 1>like that mustache in my opinion. But the interesting thing

0:37:20.400 --> 0:37:22.719
<v Speaker 1>is that, yes it has the cuttlefish ye has this

0:37:22.840 --> 0:37:26.880
<v Speaker 1>signature W shape in bright light, but it's actually circular

0:37:26.960 --> 0:37:31.840
<v Speaker 1>in low light. According to the W shaped pupil in

0:37:32.000 --> 0:37:35.360
<v Speaker 1>cuttlefish by a math ger at All, published in Vision

0:37:35.440 --> 0:37:40.160
<v Speaker 1>Research in twenty thirteen. The two main theories um were

0:37:40.280 --> 0:37:44.120
<v Speaker 1>that the shape is either for camouflage, so it's just

0:37:44.200 --> 0:37:46.600
<v Speaker 1>it has a weird pupil because it's doing all sorts

0:37:46.640 --> 0:37:50.000
<v Speaker 1>of strange things with its chromatic force to you know,

0:37:50.040 --> 0:37:53.200
<v Speaker 1>to change its its appearance and therefore it has you know,

0:37:53.239 --> 0:37:56.560
<v Speaker 1>strange things going on as high as well, or that

0:37:56.640 --> 0:37:59.120
<v Speaker 1>it has to do with distance calculations. It's coming down

0:37:59.160 --> 0:38:02.640
<v Speaker 1>to some of the same factors that we just discussed

0:38:03.080 --> 0:38:08.600
<v Speaker 1>in terms of vertical and horizontal pupils. But in this case,

0:38:08.680 --> 0:38:11.600
<v Speaker 1>the researchers proposed that the w shaped pupil might aid

0:38:11.640 --> 0:38:15.440
<v Speaker 1>in balancing out the vertically uneven light field of its

0:38:15.520 --> 0:38:19.719
<v Speaker 1>natural habitat m Okay, So here's a quote from from

0:38:19.760 --> 0:38:23.359
<v Speaker 1>that paper. Quote. While an animal's retina can deal with

0:38:23.400 --> 0:38:27.879
<v Speaker 1>a wide range of light intensities in one scene, reducing

0:38:27.920 --> 0:38:32.080
<v Speaker 1>this range would limit the need for rapid local adaptation

0:38:32.239 --> 0:38:36.719
<v Speaker 1>during vertical gaze shifts. Since cuttlefish do not have an

0:38:36.719 --> 0:38:40.319
<v Speaker 1>instant three sixty field of view, they must rely on

0:38:40.440 --> 0:38:43.920
<v Speaker 1>gaze shifts to provide them with the complete view of

0:38:43.960 --> 0:38:47.080
<v Speaker 1>the surrounding world. Okay, so they have to move their

0:38:47.080 --> 0:38:50.000
<v Speaker 1>eyes to look around them, right, and you know, in

0:38:50.040 --> 0:38:53.360
<v Speaker 1>this we have to think about light in the aquatic world,

0:38:53.840 --> 0:38:56.920
<v Speaker 1>you know, where you know, the ever present darkness of

0:38:56.960 --> 0:39:01.560
<v Speaker 1>the depths and then the periodic light field a realm

0:39:01.600 --> 0:39:04.799
<v Speaker 1>of the upper depth. And if you're something like cuttlefish,

0:39:04.840 --> 0:39:07.480
<v Speaker 1>you're having to navigate both. And it kind of comes

0:39:07.480 --> 0:39:10.920
<v Speaker 1>down to some of the ideas we're discussing with with

0:39:11.120 --> 0:39:13.319
<v Speaker 1>with load of the ground predators. You know, you have

0:39:13.360 --> 0:39:17.840
<v Speaker 1>to sort of be adaptable to both realms, but in

0:39:17.880 --> 0:39:21.280
<v Speaker 1>this case you need to be able to to simultaneously

0:39:21.360 --> 0:39:25.399
<v Speaker 1>deal with the light in the darkness. By the way,

0:39:25.920 --> 0:39:27.920
<v Speaker 1>coming out of the water for a second, the gecko

0:39:27.960 --> 0:39:31.280
<v Speaker 1>pupil I was reading about essentially as a vertical pupil

0:39:31.400 --> 0:39:35.319
<v Speaker 1>aiding in a nocturnal ambush predator's lifestyle. But it does

0:39:35.360 --> 0:39:38.680
<v Speaker 1>look really cool and they are apparently really incredible hunting

0:39:38.719 --> 0:39:41.080
<v Speaker 1>eyes according to some of the articles that I looked at.

0:39:42.640 --> 0:39:45.520
<v Speaker 1>But then, oh, another aquatic eye of note is the

0:39:45.560 --> 0:39:50.200
<v Speaker 1>dolphin pupil, and it's it's interesting that while it resembles

0:39:50.200 --> 0:39:54.520
<v Speaker 1>a horseshoe or crescent, when it's fully dilated, it constricts

0:39:54.560 --> 0:39:59.200
<v Speaker 1>down to two tiny openings that are sometimes referred to

0:39:59.360 --> 0:40:03.640
<v Speaker 1>as a double bowl. Pupil um, and this apparently comes

0:40:03.640 --> 0:40:05.839
<v Speaker 1>down to the fact that the eye the pupil shape

0:40:05.840 --> 0:40:07.560
<v Speaker 1>who with dolphins has to do with dolphins or noted

0:40:07.600 --> 0:40:10.120
<v Speaker 1>for having exceptional vision both in and out of the water.

0:40:11.120 --> 0:40:14.600
<v Speaker 1>They know, they're they're they're they're able to to position

0:40:14.640 --> 0:40:17.200
<v Speaker 1>their bodies so that they're gazing out of the water,

0:40:17.360 --> 0:40:20.720
<v Speaker 1>and they have great vision in that circumstance as well.

0:40:20.760 --> 0:40:22.920
<v Speaker 1>But I included a photograph here for you, Joe, and

0:40:22.920 --> 0:40:25.600
<v Speaker 1>I encourage listeners to look this up as well. Um.

0:40:25.840 --> 0:40:29.040
<v Speaker 1>The first picture shows the horseshoe pupil, and then the

0:40:29.080 --> 0:40:33.600
<v Speaker 1>second picture shows the double pupil when everything's fully constricted. Yeah,

0:40:33.719 --> 0:40:35.840
<v Speaker 1>it does look amazing though, if you do look up

0:40:35.880 --> 0:40:39.759
<v Speaker 1>scientific diagrams of the eye. I think what these are

0:40:40.160 --> 0:40:44.319
<v Speaker 1>explaining that's normally happening is like that the the sort

0:40:44.320 --> 0:40:48.600
<v Speaker 1>of horseshoe or or U shaped pupil when it constricts,

0:40:48.640 --> 0:40:51.160
<v Speaker 1>what it actually constricts down to is something that looks

0:40:51.239 --> 0:40:54.600
<v Speaker 1>kind of like two earbuds connected by a wire, and

0:40:54.680 --> 0:40:58.520
<v Speaker 1>the wire is just very narrow. Yes. Yes, now some

0:40:58.560 --> 0:41:01.080
<v Speaker 1>of you might be wondering, Okay, you're talking about mythic

0:41:01.160 --> 0:41:03.960
<v Speaker 1>figures with strange eyes, and now we've we've talked about

0:41:04.000 --> 0:41:07.520
<v Speaker 1>a number of different real life organisms that have some

0:41:07.560 --> 0:41:11.640
<v Speaker 1>sort of interesting eyes going on. Is it possible that

0:41:11.640 --> 0:41:15.319
<v Speaker 1>that that the myth makers and the storytellers of old

0:41:15.360 --> 0:41:18.920
<v Speaker 1>were inspired by eyes they saw in nature. And I

0:41:19.400 --> 0:41:22.719
<v Speaker 1>didn't really find anybody talking about this, I mean outside

0:41:22.760 --> 0:41:25.080
<v Speaker 1>of Yes, if you're watching some sort of modern show

0:41:25.120 --> 0:41:28.040
<v Speaker 1>and reptile people show up and they have vertical slits

0:41:28.040 --> 0:41:31.480
<v Speaker 1>and their eyeballs, yes, obviously somebody decided let's give them

0:41:31.600 --> 0:41:35.520
<v Speaker 1>reptile eyes. Um. Though again, if they're reptile people, I mean,

0:41:35.560 --> 0:41:37.719
<v Speaker 1>if they're like, I don't know, five six feet tall

0:41:37.800 --> 0:41:40.680
<v Speaker 1>or something, they should probably have round eyes. What if

0:41:40.680 --> 0:41:42.520
<v Speaker 1>they crawl around on their bellies all the time that's

0:41:42.520 --> 0:41:45.600
<v Speaker 1>how they hunt. Oh oh, okay, then yeah, vertical slits,

0:41:45.640 --> 0:41:49.279
<v Speaker 1>go for it. But I was thinking, Okay, the cuttlefish

0:41:49.320 --> 0:41:54.359
<v Speaker 1>has this amazing looking eye. Any possibility there, well, I mean,

0:41:55.960 --> 0:41:59.160
<v Speaker 1>the common or European cuttlefish can be found in Irish waters,

0:41:59.560 --> 0:42:03.240
<v Speaker 1>and cuttlefish shells or cuttlefish bones were used as ornaments

0:42:04.200 --> 0:42:07.000
<v Speaker 1>by the Celts, according to DJ Conway in the book

0:42:07.080 --> 0:42:11.840
<v Speaker 1>Celtic Magic Ireland. However, it's famously light on reptile species,

0:42:11.840 --> 0:42:15.040
<v Speaker 1>So I don't think geckos would have had an impact

0:42:15.040 --> 0:42:17.799
<v Speaker 1>on any literary motifs. And and ultimately, I don't think

0:42:17.800 --> 0:42:21.400
<v Speaker 1>anybody was pulling up any cuttlefish and checking out their

0:42:21.560 --> 0:42:24.000
<v Speaker 1>their eyeballs either or you know, I've I found nothing

0:42:24.000 --> 0:42:26.680
<v Speaker 1>to suggest that, but my mind went there, so I

0:42:26.680 --> 0:42:29.399
<v Speaker 1>thought i'd mentioned it to everybody. You know, I think

0:42:29.400 --> 0:42:32.120
<v Speaker 1>this show is a safe place to admit research dead ends.

0:42:32.320 --> 0:42:35.480
<v Speaker 1>Sometimes we just got to do that. Yeah, unless there's

0:42:35.520 --> 0:42:37.640
<v Speaker 1>a paper out there I'm missing, And if so, as always,

0:42:37.719 --> 0:42:40.640
<v Speaker 1>if there's something we've missed, right in and let us know,

0:42:40.960 --> 0:42:43.640
<v Speaker 1>we would love to be corrected. Well, should we tighten

0:42:43.680 --> 0:42:47.719
<v Speaker 1>the sphincter, constrict the pupil on this one, that's right, book,

0:42:47.760 --> 0:42:49.439
<v Speaker 1>what's what we should do. We should limit the light

0:42:49.560 --> 0:42:52.640
<v Speaker 1>coming in at this point. But we'd love to hear

0:42:52.640 --> 0:42:56.279
<v Speaker 1>from everyone out there. If there are particular mythic figures,

0:42:56.400 --> 0:43:02.600
<v Speaker 1>literary figures, pop culture examples of of multi pupil, multi irist,

0:43:02.760 --> 0:43:06.239
<v Speaker 1>multi lobed eyes, right in and let us know about them,

0:43:06.239 --> 0:43:08.680
<v Speaker 1>Send some pictures if they exist. We would love to

0:43:08.719 --> 0:43:10.640
<v Speaker 1>hear from you. Likewise, if there are other you know,

0:43:10.840 --> 0:43:13.399
<v Speaker 1>we really only spend a little bit of time here

0:43:13.440 --> 0:43:17.200
<v Speaker 1>with the animal world. There's so many fascinating animal eyes

0:43:17.239 --> 0:43:20.280
<v Speaker 1>out there, so if there are examples that you're particularly

0:43:20.360 --> 0:43:23.000
<v Speaker 1>fond of right in, let us know. And then, of

0:43:23.000 --> 0:43:25.680
<v Speaker 1>course there are other areas of this that we've just

0:43:25.880 --> 0:43:27.960
<v Speaker 1>touched on in these two episodes that we could easily

0:43:27.960 --> 0:43:31.080
<v Speaker 1>come back and discuss more about, like oh, the evil

0:43:31.160 --> 0:43:33.759
<v Speaker 1>Eye as we were discussing like that could be its

0:43:33.800 --> 0:43:37.319
<v Speaker 1>own deep dive on the show, no doubt, all right.

0:43:37.400 --> 0:43:38.960
<v Speaker 1>In the meantime, if you would like to check out
