In confirmation of his damaging statements Caccini appealed to the testimony of a Dominican, Ferdinand Ximenes, and a young nobleman, Attavanti. Both of them were afterwards called in November of the same year. It then came out that Caccini was not only an eavesdropper but a bad listener. Attavanti, who moreover was far more a disciple of the Dominicans than of Galileo, had once had a discussion with Ximenes, in their convent of Santa Maria Novella, about the proposition concerning the nature of the Godhead, but it originated entirely in scholasticism and had nothing to do with Galileo. Caccini, listening behind a partition, caught something of the conversation; and, thinking that Attavanti was a well instructed follower of Galileo, and was merely repeating what he had taught him, explained the fragments of the disputation in his own fashion, and formed them into these stupid accusations. It also appeared from the evidence of Ximenes and Attavanti that neither of them knew of anything suspicious about Galileo, except that he propounded the doctrine of the double motion of the earth.[108] After the favourable testimony of Ximenes and Attavanti the evidence of Caccini was only so far of importance that it gave rise to an inquiry into the “History and Explanation of the Solar Spots.”[109] This, and the oft discussed letter to Father Castelli then, were the grounds upon which Galileo’s enemies based the accusation of philosophical and theological error.
