Imagining the Medieval Bestiary

Medieval bestiaries, which flourished during the twelfth and thirteenth centuries, particularly in England, are compendia of brief descriptions of various animals (sometimes plants and stones are included as well), which offer moral or allegorical lessons, and are often colorfully illustrated.

Basic modern definitions often suggest a sort of binary, ontological taxonomy for the creatures in these texts: bestiaries feature “real” animals (or “actual” or “factual” ones, such as dogs, crocodiles, beavers, and elephants), but also “imaginary” ones (or “mythical,” “legendary,” or “fabulous” ones, etc., such as unicorns, phoenixes, and manticores).

Bestiaries themselves don’t appear to distinguish between “real” and “imaginary” animals, in terms of the arrangement of entries or the way that creatures from these two categories are verbally described or artistically depicted;[1] the distinction is a modern and anachronistic one. Furthermore, bestiaries’ inclusion of hard-to-believe anecdotes about well-known creatures who actually do exist (e.g., the stag’s alleged habit of drowning snakes) renders the boundary between “real” and “imaginary” animals, as we might consider it, less firm in these texts. At stake in the discourse of the “real” versus the “imaginary” in bestiaries is our view of medieval thinkers.

One approach to the “imaginary” animals in bestiaries—a very old approach to interpreting mythical creatures, in fact—is rationalistic: positing that even the legends have some basis in reality, and that real animals were, through a combination of misunderstanding and literary transmission, rendered (almost) unrecognizable. Notable proponents of this view in modern times have included T. H. White (1954), and more recently, zoologists Wilma George and Brunsdon Yapp (1991).

Phoenix from Ashmole Bestiary (Oxford, Bodleian Library, MS Ashmole 1511, f68r).

Bestiaries, for these scholars, can be read as works of natural history, albeit flawed ones, and we should perhaps extend some generosity to their creators, in light of the limitations of their knowledge. George and Yapp characterize the bestiary as “an attempt, not wholly unsuccessful or discreditable for the time at which it was produced, to give some account of some of the more conspicuous creatures that could be seen by the reader or that occurred in legends.”[2] They suggest, for instance, that the manticore—described in bestiaries as a creature with a man’s face, a lion’s body, three rows of teeth, and a tail like a scorpion stinger—was based on the cheetah; that the unicorn could actually be an oryx; and that the half-human, half-fish siren could be a Mediterranean monk seal.

Reading bestiaries as genuine, sometimes highly faulty attempts at something comparable to modern natural history is not a popular position amongst medievalist scholars of bestiaries. However, the idea of bestiaries as failed pre-modern zoology lingers in some sources aimed at popular audiences. The entry on bestiaries in the Encyclopaedia Britannica, for example, claims that the “frequently abstruse stories” in these works “were often based on misconceptions about the facts of natural history.”

As for the ontological status of “imaginary” bestiary creatures to medieval readers, i.e., whether they believed unicorns, etc. actually existed, this is hard to ascertain, and perhaps of less interest to many scholars than the prospect of examining the messages these rich works articulate on their own terms. Still, the unsupported assertion that bestiary stories were “generally believed to be true” in the Middle Ages, as the Wikipedia page for bestiaries claims, is very much in line with widespread perceptions of the period.

It is an appealing contemporary fantasy, not so much to believe in dragons or unicorns, but to believe that people really believed in them, once—a sort of vicarious experience of enchantment, accomplished not simply by imaginatively engaging with medieval works that depict fantastic animals, but by imagining more credulous medieval readers, and perhaps even by imagining oneself in their place.

To take both “real” and “imaginary” bestiary creatures as the texts present them—not seeking to sieve the factual from the fabulous, not seeking an ordinary, well-known animal behind the remarkable verbal and visual depictions that bestiaries offer—allows for, amongst other things, a certain defamiliarization of the natural world we inhabit.

Playing on the fertile ambiguities of bestiary accounts is a project by The Maniculum (a podcast series which brings together medieval texts and modern gaming, co-hosted by E. C. McGregor Boyle, a PhD Candidate at Purdue University, and Zoe Franznick, an award-winning writer for Pentiment). On the Maniculum Tumblr, readers are offered “anonymized” selections from the Aberdeen Bestiary (i.e., the name of the animal being described is replaced with a nonsense-word to disguise its identity). Contributors are invited to create artwork inspired by the bestiary description itself, rather than their knowledge of what the animal is “supposed” to look like. The results are diverse; the “hyena” entry, for instance, yielded representations of creatures resembling everything from pigs to predatory snails, in a wide range of styles.

Gendering the Harpy: Mythology, Medievalism, and Macabre Femininity

I have a fascination with the strange and obscure, and if I find oddities and curiosities during my travels that intersect with my medieval interests, even better. On a recent trip to Italy, I encountered a creature from both Greek mythology and medieval bestiaries at one of the most wonderfully macabre sites I’ve explored.

While on vacation in Rome this summer, I visited the Capuchin Crypt, an underground mausoleum containing an elaborate arrangement of human bones – lots and lots of bones. No one knows who designed the beautiful and haunting configurations comprised from the bones of approximately 3,700 bodies, presumably those belonging to Capuchin monks who sought refuge from religious persecution in France and perished while in Rome.

Unfortunately, photos are not allowed, and efforts to describe the intricacies and expanse of the design prove rather futile. Skulls and pelvic bones combine to create sculptures reminiscent of butterflies in the arches of doorways. Vertebrae dot and line the ceilings of the chambers like so many fresco tiles. Massive piles of assorted bones have been shaped into seats for carefully posed skeletons. Reviewing his experience, the Marquis de Sade rated the exhibit five stars by modern standards.

But the crypt is a 17th-century construction. It’s the museum that contains the medieval bits, and that’s where I noticed an early print book, dated to the 15th or 16th century, that clearly depicted a cockatrice and that the museum had identified as a harpy.[1] To be fair, the label included a question mark, indicating that the curator was unsure as to what kind of creature was on display.

Far less familiar than the harpy, the cockatrice is a legendary creature with a dragon’s body and a rooster’s head. The beast was believed to be hatched from a rooster’s egg incubated by either a serpent or a toad. Its first recorded mention in English appears in a Wycliffite bible dated 1382.[2]

Labeled as a koketrice in this medieval bestiary from England circa 1500, the creature combines a rooster’s head and feet with a dragon’s wings and tail. (Yale Center for British Art, Helmingham Herbal and Bestiary, folio 18v).

The cockatrice seems to have become synonymous with the basilisk in medieval bestiaries. [3] Most often, basilisks are depicted as a bird, typically a rooster, with a snake’s take. In some illustrations, the basilisk is all snake in terms of physical characteristics, though often with a crest reminiscent of a rooster’s head. The mythologies of the cockatrice and basilisk also share similar elements. As with the basilisk, it is fatal for a person to look the cockatrice in the eyes. Both creatures’ breath can also cause death according to folklore.

This medieval bestiary dated 1225-50 and produced in England portrays the basilisk as the king of serpents with lesser snakes paying homage. The creature exhibits mostly serpent features but retains the wings, legs, and crown of a cock. (Bodleian Library, MS Bodley 764, folio 93v).

A harpy, in contrast to the cockatrice, has a bird’s body with a human head and no serpent components. When I mentioned the mislabeling to the front desk staff, I was told that a historian had recently visited the museum and indicated the reverse but without additional explanation. I assured them that the rooster-headed serpent was—hands down—a cockatrice. Harpies have bird bodies, human heads, and zero snake parts. As imperatively, harpies are depicted as female.

According to Greek mythology, harpyiai were winged female spirits thought to be embodied in sharp gusts of wind, and while certainly fearsome, they were not always so bestial. Known as the “hounds of Zeus,” the female entities were sent from Olympus to snatch people or objects from the earth. Sudden disappearances were, as a result, often attributed to the harpies.

In their earliest representations, harpies appeared as winged women, sometimes with the lower bodies of birds. They were vengeful creatures but not hideous in appearance. Writing between 750 and 650 BC, Hesiod describes harpies as winged maidens with beautiful hair, whom he praises for swiftness in flight that exceeds the speed of storms and birds. Homer, writing roughly around the same time, mentions a female harpy but says nothing derogatory about her looks.

By the end of the classical period, harpies had become monstrous portraits of femininity. They were birds with the heads of maidens, their faces visibly hungry, and had long claws extending from their hands. In the writings of Aeschylus around 500 BC, they are described as disgusting creatures with weeping eyes and foul breath. Virgil, in his Aeneid dated 30-19 BC, refers to them as bird-bodied and female-faced with talons for hands, whose faces reflect insatiable hunger and whose droppings are notably vile. These grotesque portrayals of the harpy—half woman, half monster—are the most well-known from classical mythology.

Harpies depicted as winged women take food from the table of the blind king Phineus on an Athenian vase from 480 BC housed at the J. Paul Getty Museum.

Interestingly, one mythographer did stick a rooster’s head on the otherwise female body of a harpy. Writing in Rome during the 1st century AD, Hyginus describes harpies as having feathered bodies, wings, and cocks’ heads and the arms, bellies, breasts, and genitals of a human woman.[4] Still, there are no serpent parts here to suggest that a medieval image of a cockatrice might instead be a harpy based on Hyginus’s design.

During the Middle Ages, harpies may not have been so distinctly gendered, at least in their encyclopedic cataloguing. Most representations in medieval bestiaries depict the creatures with bird bodies and female faces, but several manuscript illustrations appear androgynous and some even portray the harpy with a beard. The beard, however, may not be indicative of a male beast but instead emphasize the beastliness of the female creature.

Illumination of a harpy with facial feathers reminiscent of a beard from the medieval encyclopedia Der Naturen Bloeme, or The Flower of Nature, written in Middle Dutch and produced in Flanders circa 1350 (Koninklijke Bibliotheek, KA 16, folio 75r).

Furthermore, Ovid’s retelling of the Jason story in his Metamorphoses specifically mentions the harpies having the faces of virgin women. Written in the 9th century, Ovid’s collection of myths served as a source text for many medieval writers, including Dante Alighieri and Geoffrey Chaucer, and his treatment of the harpies suggests that their association with female monstrosity continued to resonate soundly during the period.

Engraving of the harpies in the Forest of the Suicides in reference to Dante Alighieri’s Inferno by French printmaker Gustave Doré (1832-83).

Turning to the etymology of the term, the first recorded instance of harpy in English actually appears in Chaucer’s Monk’s Tale around 1405.[5] The creatures are not specifically gendered; they are simply mentioned among the monsters defeated by Hercules, at which point the text reads, “He Arpies slow, the crueel bryddes felle” [“He slew the Harpies, the fierce cruel birds”] (2100).[6] Yet one cannot help but see the feminine slippage in the spelling of “bryd,” meaning both “bird” and “bride” in Middle English.[7] Indeed, the term harpy adopts a derogatory connotation in writing by the mid- to late 15th century.[8] The term cockatrice, too, took on a negative meaning specifically with respect to women by the mid-16th century, at which point it referred to a prostitute or a sexually promiscuous woman.[9]

Illumination of a harpy with a female face from the medieval encyclopedia Liber de natura rerum, or Book on the Nature of Things, written in Latin and produced in France during the 13th century (Bibliothéque Municipale de Valenciennes, MS 320, folio 86r).

While it’s possible that the harpy may have maintained some gender ambiguity during the medieval period, contemporary etymology and ideology has synonymized the harpy with femaleness but also, importantly, with power. The sheer number of times Hillary Clinton was called a “harpy” during her presidential campaign highlights how a powerful woman was characterized as not only threatening but also monstrous while pursuing a position historically deemed male domain.[10]

Harpies in medieval fantasy films are also perched at the intersection of femaleness and power, glorious in their might regardless of how monstrous their bodies may be. The Last Unicorn, a 1982 animated adaptation of Peter S. Beagle’s 1968 novel, provides a poignant example. Captured by a traveling circus, the titular character finds herself caged across from a harpy, the only authentic creature of legend in the menagerie apart from the unicorn herself.

In a magnificently ominous scene, the audience hears the harpy before they see her. A low growl grows to a raspy screech as the harpy appears on screen. She appears more bird than human, but her grotesque body is blatantly female with three elongated breasts visible beneath her beard and boar’s tusks. A knotted tree limb cracks from the strength of her talons, and her eyes glow red with rage when her captor approaches her cage. Once freed, she kills the old woman who boasted of keeping a harpy captive when no one else could.

In The Last Unicorn, the titular character recognizes the harpy as Celaeno, the same name given to one of the harpy sisters in the Greek story of Aeneas. The unicorn is freed from her cage under the cover of night, and she then proceeds to free her fellow immortal.

Considering the harpy’s history, it seems a shame to mistake her for any other creature from Greek mythology or medieval bestiaries. She has been such a fraught representation of both femininity and monstrosity, but she has also endured as a symbol of female ferocity. Even as her beauty eroded over the centuries, her power has not waned, and her macabre femininity has never ceased to inspire fear.

Owls: Always a Hoot?

Today, owls are usually associated with wisdom. Their depictions in modern iconography range from majestic hunters to cute messengers à la Harry Potter. The convention of associating these nocturnal birds with wisdom goes all the way back to ancient Greeks and Romans depicting owls with the goddess of wisdom, Athena/Minerva. However, owl symbolism has not continuously had such positive connotations; in fact, in Medieval England, they were drastically different.

Owls have a strong presence in medieval fables and poems, many of them associating owls with the darkness and uncleanliness. Medieval poets took biblical references to owls as inspiration. For example, Job in his sorrow is referred to as the companion of owls, linking owls with mourning. In Leviticus, owls are mentioned as unclean birds. Building on these negative associations, medieval beast poems include violence towards owls. In Cuono of St. Nabor’s fable “The Peacock and the Owl,” a white peacock, symbolizing light and goodness, is violently murdered by an “envious owl” (Ziolkowski 245), and then a violent curse is wished upon the owl to avenge the death of the beautiful peacock. In the same vein, in the often-repeated story of the owlet in the hawk’s nest, the owl’s true identity is discovered when it fouls the nest—and then it is thrown out of the nest and dismembered by magpies and crows (Mann 178).

A more disturbing element of owl’s negative symbolism is their association with anti-Semitism. Owls, who are day-blind and live in darkness, were used to represent Jews in medieval England, who were said to have rejected the light of Christ and live in the uncleanliness of religious blasphemy. This accounts for the anthropomorphic appearance of some manuscript drawings of owls: they were sometimes given hooked noses to resemble Jews, and their horns represent the horned hats Jews were forced to wear.

Not all mentions of owls are completely negative, however. The Aberdeen bestiary presents a positive moralization of owls, saying that they represent Christ, who lived in the darkness (or away from view, like the owl) because he wanted to save sinners who also lived in darkness away from the light of God.

One of the most well-know medieval literary owls is in the poem The Owl and the Nightingale. The Owl and the Nightingale offer retellings of some of Marie de France’s fables, illustrating the popularity of animal fables. Significantly, the Nightingale recites the fable of the owl in the hawk’s nest to emphasize the inescapability of nature over nurture: the owl is recognized because it can’t escape its unclean nature despite being raised by a different bird. However, the poem gives the well-known story a twist, turning the usual moral condemnation of the owl on its head. The owl counters that it cannot be at fault for a nature that is common to all infants—even humans.

Owl symbolism continued to have negative associations even after the medieval period. During the Reformation, they came to be associated with Catholics, and later with Puritans (Hirsch 151)—generally with the vilified religious group du jour. Negative symbolism continued into the early modern period: in several of Shakespeare’s plays, the owl is an evil omen. Though the owl has much more positive connotations today, its history is plagued by darkness and negativity.
