In 335BC Aristotle traveled to Athens with his circle of assistants to staff his new school. Thanks to his previous bid at taking over the Academy, they were well stocked with a large range of teaching materials, gathered in Macedonia; including books, maps, & other teaching material. There, in Athens, he founded the Lyceum. 2 areas which he advanced, which are of particular interest to readers of this site were physics and astronomy.
Thanks to his ties to Macedonia, Aristotle was forced to retire to Chalcis, his mothers homeland, where he moved into a house once owned by his mother which still belonged to her family. He died there one year later at the age of 62, after complaining of stomach problems.
