The Medieval Bestiary
Origins of the Bestiary Tradition
The medieval bestiary is one of the most popular and enduring genres of medieval literature and art, a collection of animal descriptions each accompanied by a moral or allegorical interpretation that draws a spiritual lesson from the animal’s characteristics. The tradition traces its origins to the Physiologus, a Greek text probably compiled in Alexandria around the second century CE, which brought together animal lore from classical sources such as Aristotle, Pliny the Elder, and Aelian with Christian typological interpretation to create a symbolic menagerie in which every creature revealed some aspect of divine truth and offered moral instruction for the believing soul. The Physiologus is organized as a series of entries, each presenting an animal, describing its “nature” or characteristic behavior (often drawn from classical natural history combined with folk belief and imaginative elaboration), and then providing a moralization that interprets that nature as an allegory of Christ, the Devil, the human soul, or the Christian life. The Physiologus was translated into Latin, Ethiopic, Armenian, Syriac, and virtually every European vernacular, and it became the basis for the medieval bestiary tradition that flourished from the twelfth to the fifteenth centuries. The bestiary was not a work of natural history in the modern scientific sense — its purpose was not empirical observation or accurate description but moral and spiritual edification, and the animals it describes are often fantastical, their “natures” deriving from literary convention rather than observation. The bestiary’s understanding of the natural world is fundamentally symbolic: the physical characteristics and behaviors of animals are signs that point toward spiritual truths, and the purpose of the bestiary is to help readers read the book of nature as they would read the book of Scripture.
Structure and Content of Bestiary Entries
A typical bestiary entry follows a consistent and predictable structure that reflects the genre’s didactic purpose and its ultimate source in the Physiologus. The entry begins with a description of the animal’s physical characteristics and behavior, drawn from the classical tradition and often mixing accurate observation with fabulous invention. The elephant, for example, was said to have no joints in its legs and to sleep leaning against a tree — a belief that required hunters to cut the tree to capture it, symbolizing the way the Devil catches the unwary soul deprived of its spiritual support. The lion was believed to be born dead and to be brought to life on the third day by its father’s breath, making it a clear symbol of the resurrection of Christ. The pelican was believed to pierce its own breast to feed its young with its blood, making it a symbol of Christ’s sacrifice. The entry then proceeds to the moralization, which explains what the animal’s nature reveals about Christ, the Devil, the human soul, or the Christian life. The moralization typically cites Scripture, the Church Fathers, or both, grounding the allegorical interpretation in the authority of tradition. The entry often concludes with a prayer, an exhortation, or a warning to the reader to apply the lesson to his or her own spiritual life. The structure is thus designed not merely to inform but to transform, moving the reader from knowledge of the natural world to deeper understanding of divine truth to practical application in daily life.
Major Animals and Their Symbolic Meanings
The bestiary contains a rich and memorable cast of animals, each with a specific symbolic significance. The lion symbolizes Christ, royal power, and the resurrection. The fact that the lion was believed to sleep with its eyes open made it a symbol of Christ’s divine nature, which never sleeps in its watch over humanity. The unicorn, which could only be captured by a virgin, represented Christ’s Incarnation through the Virgin Mary. The phoenix, which rises from its own ashes after death, represented the resurrection of the dead and the hope of eternal life. The pelican, piercing its own breast to feed its young with its blood, represented Christ’s sacrifice on the cross and the Eucharist. The dragon and the serpent represented the Devil and the forces of evil. The fox, the craftiest of animals, represented the Devil’s cunning and the deception of worldly pleasures. The ant, the most industrious of creatures, represented the virtue of prudence and the importance of preparing for the life to come. The stag, which was believed to draw serpents out of their holes and then drink water, represented the soul that casts out sin and seeks the waters of baptism. The whale, which was believed to disguise itself as an island and then drag sailors down to the depths, represented the Devil’s deception of unwary souls. Each animal thus served as a moral exemplum, a type of Christ or the Devil, and a reminder of the spiritual realities that underlie the visible world.
The Bestiary in Illuminated Manuscripts
Bestiaries were among the most lavishly illustrated manuscripts of the Middle Ages, and their popularity owed as much to their visual appeal as to their moral instruction. The bestiary illustrations are among the most charming and inventive works of medieval art, combining naturalistic observation (in the case of familiar animals such as horses, dogs, and birds) with imaginative fantasy (in the case of mythical creatures such as dragons, griffins, and unicorns). The illustrations were not merely decorative but functional, helping readers to visualize the animals and to remember the moral lessons associated with them. The relationship between text and image in bestiary manuscripts is complex and reciprocal: the text provides the allegorical interpretation, while the image provides the visual anchor that makes the interpretation memorable. The most famous bestiary manuscripts include the Aberdeen Bestiary, the Bodleian Library’s Bestiary, and the Ashmole Bestiary, all produced in England in the twelfth and thirteenth centuries.
Influence on Literature
The bestiary tradition influenced a wide range of medieval literature beyond the genre itself. The animal symbolism of the bestiaries permeates the sermons, homilies, and devotional literature of the period. Preachers used bestiary exempla in their sermons to illustrate moral points and to make their teachings memorable. The bestiary also influenced the development of allegorical poetry, providing a vocabulary of animal symbols that poets could draw on in their work. Chaucer uses bestiary imagery in the Canterbury Tales, and the tradition of animal symbolism continued to influence English poetry well into the Renaissance. The bestiary tradition even influenced the development of heraldry, as the symbolic meanings of animals were incorporated into the coats of arms of noble families.
The Bestiary and Medieval Theology
The bestiary reflects a distinctively medieval understanding of the relationship between the natural and the supernatural. For the medieval reader, the natural world was not a closed system of cause and effect but a book written by God in which every creature had a meaning beyond its physical existence. The bestiary thus represents a way of knowing that is fundamentally different from modern science: it is not concerned with what animals are in themselves but with what they signify, not with the objective facts of natural history but with the spiritual truths that the natural world reveals. This way of knowing the world through symbolic interpretation was applied not only to animals but to stones (in the lapidary tradition), plants, and even numbers.
The Decline of the Bestiary
The bestiary declined as empirical observation replaced allegorical interpretation in the study of nature during the Renaissance and the scientific revolution. The new emphasis on direct observation and classification made the fabulous animal lore of the bestiaries seem naive and unscientific. However, the bestiary tradition never completely died out. Its influence persisted in the symbolic use of animals in literature and art, and the modern revival of interest in medieval culture has led to renewed appreciation of the bestiary as a unique and fascinating genre that reveals the medieval habit of reading the world as a book written by God.
