Bestiary - History

History

The earliest bestiary in the form in which it was later popularized was an anonymous 2nd century Greek volume called the Physiologus, which itself summarized ancient knowledge and wisdom about animals in the writings of classical authors such as Aristotle's Historia Animalium and various works by Herodotus, Pliny the Elder, Solinus, Aelian and other naturalists.

Following the Physiologus, Saint Isidore of Seville (Book XII of the Etymologiae) and Saint Ambrose expanded the religious message with reference to passages from the Bible and the Septuagint. They and other authors freely expanded or modified pre-existing models, constantly refining the moral content without interest or access to much more detail regarding the factual content. Nevertheless, the often fanciful accounts of these beasts were widely read and generally believed to be true. A few observations found in bestiaries, such as the migration of birds, were discounted by the natural philosophers of later centuries, only to be rediscovered in the modern scientific era.

Mediaeval bestiaries are remarkably similar in sequence of the animals of which they treat. Bestiaries were particularly popular in England and France around the 12th century and were mainly compilations of earlier texts. The Aberdeen Bestiary is one of the best known of over 50 manuscript bestiaries surviving today.

Two illuminated Psalters, the Queen Mary Psalter (British Library Ms. Royal 2B, vii) and the Isabella Psalter (State Library, Munich), contain full Bestiary cycles. The bestiary in the Queen Mary Psalter is found in the "marginal" decorations that occupy about the bottom quarter of the page, and are unusually extensive and coherent in this work. In fact the bestiary has been expanded beyond the source in the Norman bestiary of Guillaume le Clerc to ninety animals. Some are placed in the text to make correspondences with the psalm they are illustrating.

The Italian artist Leonardo da Vinci also made his own bestiary.
