A book about animals—and the soul

The Aberdeen Bestiary, made in England in the early 13th century, belongs to a tradition in which descriptions of animals were meant to carry religious meaning. Its writers and artists were not aiming for the standards of a modern zoology book. They drew on older compilations, especially the Physiologus, a collection that paired stories about creatures with Christian lessons. A lion, bird, or imagined beast could therefore serve as an example of virtue, sin, or salvation.

These accounts often mixed observation with inherited lore. A creature’s supposed habits mattered less as biology than as material for an analogy: if an animal was said to behave in a particular way, a writer could turn that behavior into a lesson about human conduct or Christian belief. The drawings made the stories visible, but they did not make the claims reliable descriptions of nature.

The image was part of the argument

Producing the manuscript demanded skill and costly materials. Artists used vivid pigments and gold leaf—the thin sheets of real gold applied to a surface—to make selected passages and figures gleam. That splendor helped give the book visual authority and made its pages compelling objects, not merely containers for text.

The images also helped readers follow a sequence of creatures and their moral associations. They were not simply attempts to record what an illustrator had seen in the wild. Some animals were familiar; others came to the page through texts and stories. When a depiction looks strange to modern eyes, it may reflect that chain of transmission as much as an individual artist’s choices.

The bestiary turns the natural world into a reading exercise: a creature’s story points beyond the creature itself. Its lavish finish makes that medieval way of interpreting nature unusually tangible—the gold catches the eye, while the text asks the reader to look for a lesson.
