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).

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.

Bestiaries continue to fascinate and inspire, centuries after their creation. Below are some medieval bestiary facsimiles and related resources to explore:

  • The Aberdeen Bestiary (Aberdeen, Aberdeen University Library MS 24), written and illustrated in England ca. 1200. Digital facsimile, accompanied by commentary, and Latin transcriptions and modern English translations of each folio.
  • The Ashmole Bestiary (Oxford, Bodleian Library, MS Ashmole 1511), early 13th century, England, possibly derived from the same exemplar as the Aberdeen bestiary. Digital facsimile.
  • The Worksop Bestiary (New York, Pierpont Morgan Library, MS M.81), ca. 1185, England. Digital facsimile.
  • The Medieval Bestiary: Animals in the Middle Ages, a website on bestiaries by independent scholar David Badke. Includes indices of bestiary creatures, cross-referenced with manuscripts and relevant scholarship, as well as galleries of medieval illustrations.

Weigh Your Books! An Interview with Dr. Andrew Irving

This week, we’re revisiting the first published episode of “Meeting in the Middle Ages.” Back in 2022, we sat down with Dr. Andrew Irving, assistant professor of religion and heritage at the University of Groningen. We spoke to him about his journey to Medieval Studies, his work on the 11th century Uta Codex, why one should always weigh their books, and why liturgy is like a Wagnerian opera.

Dr. Irving’s story is one of a truly international scholar. A native of New Zealand who moved to the US to study for his PhD at Notre Dame, he now works in Europe on a broad range of medieval subjects. His stories of archival work highlight some of the unexpected challenges that researchers can face: limited access to resources, unconducive weather (it helps to examine books in “raking light”), or flat out denied permission to consult a manuscript. Traveling to another country to visit a library and examine its rarest materials can be intimidating, especially for young scholars. But Dr. Irving demonstrates that a personal connection and diligent preparation can pave the way for a smooth experience. It’s an instructive tale for young scholars, and sheds light on a part of scholarly work that may seem mysterious to the uninitiated.

Dr. Irving’s work is about place. His career has taken him all over the world, of course. But the place in which texts exist is also paramount. Through his work on texts like the Uta Codex, he provides some great examples of how a manuscript has to be considered in terms of its home. Where was it kept? What was the environment? What was the history of that home? Was it ever destroyed, raided, burned? If it was a written document, was it read aloud? To whom? Was it carried about? How much did it weigh? All of these questions must be asked to get at the truth of an object. A text has to be wrestled with on its own terms—in isolation—but this is only half the story. Each historical artifact is living history: it was created by someone for someone or something. We have to be prepared to engage with it in a multitude of ways. We must be historians, linguists, theologians, art historians, literary critics, and more. That is what it is to be a medievalist.

Thanks for listening. See you next time in the Middle Ages.

By the Bones of Saint Cuthbert: Books, Embroidery, and Bodily Incorruption

When the Vikings invaded the northeastern coast of Britain in 793, they raided the monastery at Lindisfarne. The monks fled – and they carried with them the remains of Saint Cuthbert.

His coffin not only contained a corpse but also material relics, the Saint Cuthbert Gospel among them. The book so well preserved in his coffin has been recognized as a marvel among medieval manuscripts, along with the Lindisfarne Gospels, which the monks also saved from destruction by the Danes. Much like these extraordinary books, the embroidery that survived alongside Saint Cuthbert’s body is remarkable for its rarity.

The Lindisfarne Gospels has, as the British Library says, “long been acclaimed as the most spectacular manuscript to survive from Anglo-Saxon England.” Created circa 700, the elaborately decorated manuscript contains the four Gospels, which recount the life of Christ, as well as other associated texts.

Cuthbert of Lindisfarne was born in 634 and spent his life as a monk, bishop, and hermit in the Kingdom of Northumbria. When he died in 687, he was buried at Lindisfarne. As the Venerable Bede recounts the story, Saint Cuthbert’s coffin was opened again 11 years later with the intention of removing his bones to a reliquary, but his body was found to be perfectly preserved.

From Bede’s “Life of Saint Cuthbert,” British Library MS 39943, dated 1180.

Under the duress of Danish attack, it was more than 100 years before the monks laid Saint Cuthbert to rest in Durham, where they settled in 995. Several artifacts accompanied Saint Cuthbert as he traveled posthumously around the English countryside, and the book and embroidery are very special for their survival.

The Saint Cuthbert Gospel was discovered when the coffin was opened at Durham Cathedral in 1104, and like the body of its patron, the book remained incredibly well preserved. Dated to the early 8th century, it is the earliest European book to retain an original, intact binding.[1] The covers are made from goatskin that has been dyed red and decorated; the tooled leather is stretched over wooden boards, most likely birch. It is a pocket-sized book measuring 5.4 by 3.6 inches, and the manuscript contains the Gospel of Saint John.

Housed at the British Library in London, the Saint Cuthbert Gospel can sometimes be seen on display in the Treasures of the British Library exhibition, sometimes alongside the Lindisfarne Gospels. Photo of the front cover of the Saint Cuthbert Gospel, courtesy of the British Library.

The British Library’s description of the binding beautifully correlates the book’s cover with its content. On its front cover, “the central motif of a stylised vine sprouting from a chalice reflects Christian imagery from the eastern Mediterranean. The plant on the cover of the Gospel has a central leaf or bud and four fruits, echoing the text, ‘I am the vine, you are the branches’, from St. John’s Gospel 15:5.”[2] On the back cover appears “rectangular borders containing a geometric, step-pattern double-armed cross, recalling John’s central role in the Crucifixion narrative.”[3]

The other relics were discovered much later when Saint Cuthbert’s tomb was opened in 1827. In addition to the saint’s body, Canon James Raine found a pectoral cross, a portable altar, an ivory comb, and a set of embroidered vestments.[4] The vestments, or religious robes, date between 909 and 916 and are the earliest pieces of embroidery that survive from the medieval period in England.

Only a few pieces of Anglo-Saxon embroidery survive at all, and these pieces are unique among the extant examples in that they feature full-length human figures. The vestments include a stole decorated with figures of Old Testament prophets and Apostles, as well as a maniple, a girdle, and bracelets. They are made from Byzantine silk with silk and gold thread decoration. According to inscriptions on the fabric, the vestments were commissioned by Queen Aelfflaed for the Bishop of Winchester and produced between 909 and 916. Her stepson, King Athelstan, who ruled England from 927 to 939, placed them in Saint Cuthbert’s tomb when he visited the shrine in 934.

The style of embroidery called Opus Anglicanum, or English Work, was used on clothing, hangings, and other textiles, often created with silk and gold or silver-gilt threads stitched on linen or velvet backgrounds. Between the late 12th and mid-14th centuries, these luxury goods were in great demand across Europe. Often they were procured as diplomatic gifts, and they were very expensive. They were produced for both secular and ecclesiastical use, but most of the surviving examples were designed for liturgical use like those found alongside Saint Cuthbert.

Although English embroidery was renowned for its beauty during the medieval period, the majority has been lost to neglect or destroyed for the extraction of precious metals or stones, such as pearls and other jewels mentioned in inventory descriptions. Fragments, however, can be found in museums, and one of the most substantial collections of Opus Anglicanum can be found at the Victoria and Albert Museum in London.

Embroidered in the Opus Anglicanum style, the Butler-Bowdon Cope is a ceremonial cloak that was created circa 1330-50 for use in church services and processions. The embroidery incorporates gold, silver, and colored silks, as well as freshwater seed pearls and glass beads, and depicts events from the life of the Virgin Mary.

The vestments recovered from Saint Cuthbert’s tomb can be seen on display at Durham Cathedral, where visitors can view the entire Treasures of Saint Cuthbert collection. The oak coffin made to cradle the saint’s body when he was found incorrupt in 698 also resides among the relics, its own fragmented body a reminder of what arduous travels medieval artifacts endure to remain with us in our own time.
