Abstract

From time immemorial through January 6, 1610, there was only one moon known in all the heavens. That moon was our own moon, which even after the Copernican revolution had dethroned the Earth from the center of the orbits of the Sun and other planets, still continued faithfully to circle the Earth). One week later there were five moons—four others had been added.
