In this post I described a statue of an astronomer in the Piazza dei Signori, but couldn't remember his name. A helpful reader sent me a reminder (grazie, Babbo!). The gentleman is Girolamo Fracastoro (ca. 1476-1553), a colleague of Copernicus and professor of logic at the University of Padua. He made some scientific contributions in the field of medicine as well as astronomy, and you can read more about him here.
