"La legha del pippione". "Pippione" is a pun on Colombe's surname—which is the plural of the Italian word for dove. Galileo's friends, the painter, Lodovico Cardi da Cigoli(in Italian), his former student, Benedetto Castelli, and a couple of his other correspondents often referred to Colombe as "il Colombo", which means "the Pigeon". Galileo himself used this term a couple of times in a letter to Cigoli of October, 1611 (Edizione Nazionale 11:214). The more derisive nickname, "il Pippione", sometimes used by Cigoli (Edizione Nazionale 11:176, 11:229, 11:476,11:502), is a now archaic Italian word with a triple entendre. Besides meaning "young pigeon", it is also a jocular term for a testicle, and a Tuscan dialect word for a fool.
