If you’ve never heard of this lady, now is the time to make her acquaintance. Ada is a wealth of information, especially regarding Rome and Florence. (Not to mention old manuscripts).
I first found her site doing some lookie-loo on the ‘Net for Machiavelli.
Unfortunately, she took new job, and hasn’t been posting for some months.
There is enough on her site, here, to keep a reasonable nerd happy for several days.
