Seven of the 10 tribunal cardinals signed a condemnation of Galileo. The condemnation found Galileo "vehemently suspected of heresy" in teaching as truth that the Earth moves and is not the center of the universe. He was found guilty in persisting in such teaching when he had been formally warned not to do so in 1616. His book was prohibited, he was ordered confined to formal imprisonment, to publicly renounce his beliefs, and to perform proper penance. Two additional articles – claiming he had fallen away from Catholic practice and that he had obtained an imprimatur for the Dialogue deceitfully – Galileo refused to admit and they were withdrawn. Galileo signed a handwritten confession.
