Drake, (1970, pp.191–196), Linton (2004, pp. 211–12), Sharratt (1994, p. 166). This is not true, however, for geocentric systems—such as that proposed by Longomontanus—in which the Earth rotated. In such systems the apparent motion of sunspots could be accounted for just as easily as in Copernicus's.
"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, 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.
