Has anyone heard about the Aberdeen Bestiary

I recently came across it. It is from the 15th century, with animal designs and some religious motifs. It is based on Physiologus from 4th century. I found it quite interesting. You can find more and more ancient texts via the internet, which is so great.

""The Physiologus was written in Greek, probably in Alexandria, in about the fourth century. It consisted of 48 or 49 chapters about beasts, birds and stones used as a vehicle for explaining Christian dogma. Its stories come from very ancient sources: Indian, Hebrew and Egyptian animal lore and various classical natural philosophers like Aristotle and Pliny. A moralising Christian gloss was added to these stories by a person presumably known as Physiologus. ""
