Galileo then wrote a book entitled Dialogue on the Great World Systems. Although the pope had ordered Galileo to be neutral, the book came across as favoring Copernicus’ conclusions. Soon Galileo’s enemies were claiming that his book ridiculed the pope. Accused of heresy and threatened with torture, Galileo was forced to deny the teachings of Copernicus. In 1633, the Roman Inquisition sentenced him to perpetual house arrest and banned his writings. Galileo died at home in Arcetri, near Florence, on January 8, 1642.
