Another book you might like to look into is one in the series of books 
about China written by Joeseph Neadham.  He wrote huge volumes about 
Chinese technology and inventions with a book about astronomy  and 
calenders.  To the ancient Chinese the calender was very important for 
the mainly agrarian society and so the emperor in power issued very 
precise calenders.  You mat find something on Gutenberg.
