Summary
In this book, Grassi responded to the criticism of Guiducci/Galileo. Comets seemed to provide a test of the Copernican and Tychonic systems: if the Earth were moving, then with three comets, one might have hoped to see at least one of them retrograding. In the controversy over the comets, the Jesuits began increasingly to ally themselves with the Tychonic system.
