“Galileo,” găl-i-leeˈo. (1564-1642.) An illustrious astronomer, mathematician and philosopher, the creator of experimental science. He made a number of important discoveries in the science of astronomy, among which were Jupiter’s satellites, Saturn’s rings, the sun’s spots, and the starry nature of the milky way. He was a strong advocate of the Copernican system—which represents the sun to be at rest in the center and the earth and other planets to move round it—and for this was twice persecuted by the Inquisition. On both occasions he was publicly compelled to abjure the system, but the last time he is said to have stamped his foot while muttering to himself, “but nevertheless it does move.” The later years of his life were spent in his country house near Florence.
