Georgios Koressios was one of the most important Greek theologians and scholars of the 17th century. Born on the island of Chios between 1567 and 1570, he studied Philosophy and Medicine at the University of Padua. In 1611 he was appointed professor of Greek language and literature at the University of Pisa, where he demonstrated his strong admiration for the work of Aristotle. During his years in Pisa, he engaged in an ideological conflict with his colleague Galileo Galilei, based on the latter's writings on the nature of solid bodies.
