GALILEO PROJECT
I devoted much of my college career to studying the Renaissance. I've recently rediscovered that interest, focusing particularly on Galileo and his milieu. And I just came across the Galileo Project, a cool site on just that subject, put together by historians and students at Rice University.
On a side note, Galileo's elder daughter, the subject of Dava Sobel's Galileo's Daughter, was originally named Virginia. She took the name Maria Celeste, in honor of her father's cosmological studies, when she entered a convent. [Posted 3/7.]
