I was sent this one by a thoughtful reader.  An online, fully translated and indexed Medieval Bestiary, The Aberdeen Bestiary.  Very good stuff!  

A sample:

The third characteristic of the lion is that when a lioness gives birth to her cubs, she produces them dead and watches over them for three days, until their father comes on the third day and breathes into their faces and restores them to life. Thus the Almighty Father awakened our Lord Jesus Christ from the dead on the third day; as Jacob says: ‘He will fall asleep as a lion, and as a lion’s whelp he will be revived’ (see Genesis, 49:9). 

say what?
