But his ideas were considered heretical, and Galileo was called to appear before the inquisition in Rome in 1633. Galileo wrote a book " Dialogue Concerning the Two Chief World Systems, Ptolemaic and Copernican" and dedicated it to the Pope Urban VIII. The more Galileo looked, the more he was convinced of the sun-centered Copernican model of the planets. His August 1609 drawings of the moon predate Galileo's, but were never published. Harriot became famous for his travels to the early settlements in Virginia to detail resources there. Thomas Harriot, a British ethnographer and mathematician, also used a spyglass to observe the moon. He also discovered the rings of Saturn, sunspots and four of Jupiter's moons. He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky - the Milky Way. Galileo was the first to point a telescope skyward. The Senate, in turn, set him up for life as a lecturer at the University of Padua and doubled his salary, according to Stillman Drake in his book " Galileo at Work: His Scientific Biography" (Courier Dover Publications, 2003). He made some improvements - his creation could magnify objects 20 times - and presented his device to the Venetian Senate. In 1609, Galileo Galilei heard about the "Dutch perspective glasses" and within days had designed one of his own - without ever seeing one.
