Renaissance architecture  

Oh very good! I Particularly the paragraph on Theory. It is an excellent addition. 

Now, about those bits that you "fleshed out" .... I have been considering moving the lengthy discussion of Italian Renaissance architects to a new page Italian Renaissance architecture
or Architecture of the Italian Renaissance...  
Anyway, there have been well-intentioned complaints that Italy is given more space than all the other countries put together (sigh!) so, since the article is very long, and you have now written an excellent summary of Italian Ren. Arch., it's probablyy the time to do it. Only, not right now this minute because it's 3.00 am and I've got lots of noisy visitors tomorrow. 

Ciao! 

By the way- you need to reference everything, otherwise you are accused of putting up "original material" so even if you've lectured in the subject for the last 40 years, you have to quote someone else who supports you, OK?
