The Trial of 1633
In 1632, Galileo published a book known as "Dialogue on the Tides," but Cardinal Bellarmine advised him against naming it that because it implied that Galileo actually felt his idea was real (of course, he did but he would get in deep trouble with the Vatican). So, Galileo renamed it to "Dialogue Concerning the World's Two Chief Systems World-Ptolemaic and Copernican." However, this did not prevent him from being arrested by the church. In 1633, a trial was held. At the trial, it turned out someone showed the Pope an unsigned memo written by the Inquisition not even allowing Galileo to describe the Copernican system. Galileo's affidavit had no effect. The book was banned, and Galileo abjured, for he would face great consequences if he didn't. He was confined to his villa and put on house arrest for ten years. He didn't stop believing in his ideas, though, and he wrote another book about his ideas.
