Medieval Animal Psychology and the Mirror Self-Recognition Test

If you put a puppy or a kitten in front of a mirror for the first time, how would it react? Social media is full of videos of dogs sniffing or barking at themselves in mirrors, and cats trying to fight their own reflections. Adorable though this scenario may be, some psychologists see it as something deeper, a test of self-awareness.

Charles Darwin was once struck by an orangutan named Jenny gazing into a mirror and wondered whether she recognized herself. Over a century later, psychologist Gordon G. Gallup designed an experiment to test this, marking the faces of chimpanzees with a small amount of dye and observing their reactions when placing a full-length mirror before them.1 Although the experiment’s methodology and assumed implications have been criticized on a number of different fronts, this Mirror Self-Recognition (MSR) test has since been adapted to study a variety of different animals over the years. Orangutans, chimpanzees, dolphins, orcas, magpies, and ghost crabs have supposedly passed versions of the test; dogs, cats, giant pandas, baboons, and cichlids have supposedly not.

Failing the test has been taken to imply a lack of self-awareness, which could in turn have significant evolutionary and cross-species implications. As Jennie Coy explains, in order to cooperate like a human is (at least theoretically) able to, ‘an animal has to be sufficiently aware of itself: first, to place itself in relation to the environment; secondly, to perceive itself as having an effect on that environment; and, thirdly, to be aware of the other individual as separate from itself.’2 Self-awareness has controversially been even further connected to questions of intelligence and rationality, traits that have in the past been considered unique to humans and thus separating them from non-human animals. As recently as 1988, Tim Ingold noted, ‘The view that non-human animals may be regarded as self-conscious subjects with thoughts and feelings of their own is still something of a heresy in ethological and psychological circles.’3

Darwin’s observations and the MSR test came well after the Middle Ages, but there are a few medieval tales reflecting the underlying premise that certain animals are unable to recognize their own reflections. The first is a fable commonly titled ‘The Dog and Its Reflection’. Aesop’s version of the fable describes how a dog carrying a piece of meat sees its reflection in a body of water. Thinking that it is looking at a different dog with another piece of food, it opens its mouth to attack. In doing so, it drops its own food in the water, leaving it with nothing.

Aberdeen University Library, Univ. Lib. MS 24, fol. 19r.

This was an extremely popular fable, with versions of it adapted across the world and throughout the Middle Ages. The c. 1200 Aberdeen Bestiary, for instance, describes the dog losing meat upon seeing its shadow as a somewhat convoluted allegory for preachers ‘driving off the ambushes laid by the Devil’. In most renditions, the fable is used as a more straightforward moral message against greed; in some others like in the thirteenth-century Icelandic Hemings þáttr, the message is more political.4 Whatever the subtext may be, every version of the fable is based on the assumption that a dog would not be able to recognize its own reflection.

A second similarly confused animal is the tiger. Medieval animal texts like the Aberdeen Bestiary describe a somewhat cruel ploy to capture a tiger cub and escape the wrath of its mother: ‘When [the thief] sees the tigress drawing close, he throws down a glass sphere. The tigress is deceived by her own image in the glass and thinks it is her stolen cub. She abandons the chase, eager to gather up her young. […] And thus, trapped by the intensity of her sense of duty, she loses both her revenge and her child.’

Aberdeen University Library, Univ. Lib. MS 24, fol. 8r.

This case is slightly more complex. Like the fable dog, the tigress is unable to recognize its own reflection, but does at least evidently understand the reflection to be a familial member of its own species. Of course, the small size of the glass sphere contributes to this confusion, as does the ‘intensity of her sense of duty’ as a mother.

There is an unstated but strong assumption across both stories that a human being would be able to correctly parse their reflection and not succumb to the same errors as the other animals. Reflection stories about humans or half-humans from Narcissus to mermaids are usually concerned with the dangers of pride, vanity, and luxury, but this is all the price of human intelligence. As Joyce Salisbury explains, to medieval philosophers, ‘the main principle defining animals was their perceived lack of intellect, “reason.”’5 The dog and tiger bestiary stories suggest that self-awareness was also tied to human intellect and reason at this time, and, in fact, centuries before Darwin and Gallup, a medieval Mirror Self-Recognition test was already being theorized.

The Ambiguous Medieval Bat: Fables on Treachery and Survival

In the Middle Ages, the bat was understood to occupy an unusual position amongst animals. Ancient and medieval authors were well aware that while bats have wings and fly, like birds do, they also have teeth, give birth to live young, and produce milk—none of which are avian traits. Premodern taxonomies (systems of classification for living things) differed significantly from modern ones;1 the bat in the medieval period was often spoken of as a bird with some “quadruped” characteristics.2 For example, some twelfth-century bestiaries, drawing directly from Ambrose’s Hexameron (Book 5, 24.87), say:

The bat [vespertilio], an ignoble animal, takes its name from “evening” [vespere]. Moreover, it is both flying and a quadruped, and uses its teeth, which you may not be accustomed to finding in other birds. It gives birth like quadrupeds, not as eggs, but as living young.3

Illustration of a bat from the early 13th c. Ashmole Bestiary (Bodleian Library, MS. Ashmole 1511), fol. 63r.

The bat’s liminal nature was fodder for medieval fables as well. The most popular medieval bat fable (or at least, the one extant in the greatest number of versions)4 was The Bat and the Birds (Perry Index 566). In this fable, a bat attempts to play both sides in a conflict between quadrupeds and birds, and is ultimately punished for his duplicity.

Ambiguity as Deceptive

A Latin verse version by medieval English author Alexander Neckam, who lived in the late twelfth to early thirteenth century, goes as follows:

De vespertilione et avibus
Quadrupedes et aves gererent dum bella furentes
et modo quadrupedes, nunc fugerent volucres,
versutus vespertilio se iunxit utrisque
ut, quicquid fieret, tutus untrinque foret.
Auribus et mammis se quadrupedem simulabat,
credi par alis alitibus poterat.
Hac se fraude tegens inter fera prelia tutus
fallebat stolidum cautus utrumque genus.
Ut fraus nota fuit, genus hunc abiecit utrumque
et merito placuit ut neutrum neutri.
Hac re quadrupedes et aves dum vespere pausant,
antique fraudis conscius ipse fugit.
Sic qui se fallax nunc his nunc ingerit illis,
omnibus ingratus, iure repulsus erit.5

My translation:

The Bat and the Birds
While the quadrupeds and birds were waging a furious war, and at times the quadrupeds were fleeing, at other times the birds, the cunning bat united himself to both, so that, whatever happened, he would be safe from both sides. He resembled the quadrupeds in his ears and teats, and could be taken for a bird because of his wings. So, deceptively hiding himself, safe amongst the fighting beasts, the cautious one tricked the foolish ones of both kinds. When the deceit was known, both kinds cast him out, and he deservedly was accepted by neither one nor the other. Because of this, when quadrupeds and birds rest in the evening, he, conscious of the earlier deception, flees. Thus, whichever deceitful one pushes himself onto first some, then onto others, will justly be rejected, unacceptable to all.

The bat in the fable of The Bat and the Birds values self-protection above “loyalty” to one party or another, and sits uneasily between categories. Neckam’s version construes his strategy as clever, but deceptive, and judges his ultimate status as an exile as well-deserved, and perhaps inevitable.

Illustration of the War of the Birds and the Beasts, in an 1863 edition of Croxall’s Fables of Aesop, p. 228.

While Neckam’s moral is pretty general, moralizing the conflicting groups as “some” and “others” whom one shouldn’t act fickle towards, other medieval (and modern) moralists were more direct in casting the fable in political terms. William Caxton’s Aesop (1484) proclaims:

And therfore he that wylle serue two lordes contrary one to other may not be good ne trewe/ And they whiche relynquen and leue theyr owne lordes for to seruve another straunger/ whiche is enemy to theyr lord/ ben wel worthy to be punysshed/6

(And therefore, he that will serve two lords opposed to one another cannot be good or faithful. And those who abandon and leave their own lords to serve another foreigner who is enemy to their lord are well worthy to be punished.)

Eighteenth-century churchman Samuel Croxall, meanwhile, waxed fervent about deserters and traitors to one’s country:

For any one to desert the interest of his country, and turn renegado, either out of fear, or any prospect of advantage, is so notoriously vile and low, that it is no wonder if the man, who is determined in it, is for ever ashamed to see the sun, and to show himself in the eyes of those whose cause he has betrayed.7

Illustration of a bat from a bestiary, British Library, Harley MS 3244, folio 55v.

The bat’s ambiguous nature does not jibe well with Caxton’s and Croxall’s denouncements, which compare him to someone who deserts their lord or betrays their country. Indeed, perhaps his nature, as the fables have it, does not jibe well with the genre’s broader tendency to naturalize and essentialize social categories, by using animals as metaphors for humans, as I have discussed in previous posts. Fables map species differences to human social differences, and in so doing, often portray these social differences as inherent and immutable—stark as the differences between a donkey and a lion, or a wolf and a sheep.

But, after all, which group should the bat try to belong to, in this fable? If he were to side only with the quadrupeds, the birds might deem him a traitor, and vice versa. His characteristics align him with both sides. In a sense, by allying with both sides at different points in time, he is being true to his own nature, which is ambiguous. This ambiguity can render him safer, but it can also render him more vulnerable.

Ambiguity as Adaptive

Another bat fable depicts the bat’s ambiguous characteristics as potentially adaptive in the face of danger, and indeed as something for humans to emulate. In the fable of The Bat and the Weasel (Perry Index 172), a bat is captured by a weasel and pleads for his life. The weasel insists that she cannot spare the bat, since she is the enemy of all winged creatures. Declaring that he is not a bird, but a mouse, the bat is freed.8 Then, he is caught by a second weasel, who claims to hate all mice. The bat now insists he is not a mouse, but a bat, and he is once again released. The conclusion: “The fable demonstrates that we too must not persist in the same devices, reckoning that those who adapt themselves to circumstances often escape dangers.”9

Together, these bat fables speak not only to the perceived ambiguity of the bat as a creature, but the perceived ambiguity of being ambiguous. Those who don’t fit into a single category can face mistrust and disapprobation, but that same liminality can also be a source of strength.

“My Mother Told Me”: Egils saga to History Channel’s Vikings

Like many viewers, I quite enjoyed the History Channel’s TV show Vikings. Despite the historical inaccuracies, the altered timelines and invented kinship bonds, in addition to the misrepresentations and adaptations of characters and events, I appreciated the intergenerational quality that seemed to translate that rare quality embedded within the Old Norse-Icelandic sagas. And, the version of Þat mælti mín móðir “My Mother Told Me” featured in their Season 4, Episode 9 (“Death All ‘Round”) burrowed into my mind like an ear-wyrm.

Like many, I looked into the origins of the song, and was delighted to learn about its genesis in Egils saga. The verse (lausavísa), attributed to the famous Icelandic warrior-poet Egill Skallagrímsson, comes from Egils saga (chapter 40), where a young Egill describes his youthful ambitions to become a Viking voyager. The saga survives in medieval Icelandic parchment and paper manuscripts (such as the 15th-century Möðruvallabók or later transcriptions housed in Icelandic manuscript collections). 

As I read the Old Norse-Icelandic lyrics one thing caught my eye and demanded my attention. The line: fara á brott með víkingum “fare away with the vikings” (4).

I wondered what made the Michael Hirst choose to translate that one line so differently? I mean the rhyme is catchy, sure, but the decision to erase vikingum “vikings” from the song baffled me. This would be something to emphasize, in my mind, or at the very least keep in tact, rather than remove. And, like Dr. Jack Crawford, I was intrigued to think about how the original could be versified.

After singing this song with FaeGuild Wonders’ cast in both Old Norse-Icelandic and modern English (Vikings-version) for a number of years at Enchanted Orchard Renaissance Faire and the NorthFolk NightMarket, I was inspired to again team up with my twin brother, Tom Fahey (Totem Faehy). We cocreated a new project, Brothers Grimm, with the mission to bring the medieval into the modern imaginary, in collaboration with his neofolk band, Winds of Alluria, in order to bring my own version of the song to life that blended the Vikings-version, the Old Norse-Icelandic poem, and my original translation.

Accompanied by an imagined rowing rhythm, we used samples to create an aural texture, much like we did in our first Brothers Grimm collaboration on Deor. In order to hear the song, and to see the original Old Norse-Icelandic texts and both modern English translations, see Þat mælti mín móðir.
