Radio silence is over...
Are you going to be in London in the next month? If so, you should take yourself over to the British Library to check out Royal Manuscripts: The Genius of Illumination. Open until March 13, 2012, the BL is showing the best examples of the medieval and Renaissance manuscripts made for the kings and queens of England.
This excellent bestiary, Royal 12 C XIX, is part of the exhibit. One favorite of mine is this copy of the Secretum Secretorum made for Edward III. Here's Aristotle explaining the effects of celestial bodies on plants:
There's also a multi-part BBC Four documentary about the manuscripts in the exhibit, including this one.
