Konrad Kyeser's Bellifortis

[pjburkshire]

My theory about the drawings is independent of the Chinese Theory.  It says that most of the drawings are just decoration provided by the Scribe, with minimal instruction by the Author. 

For example, for each Zodiac diagram  I think he told the scribe only "Arrange these 30 labels in two concentric circles, with a nymph and a star next to each. Then in the center draw an archer, like the one in this book here".  

Why the odd collection and not the standard 12?
