 In 343 Aristotle was asked by Philip II of Macedon to tutor his son Alexander. By 335 he had returned to Athens, now under the control of his former student Alexander. With Theophrastus he founded a ‘school’ in a public sanctuary known as the Lyceum. He headed the Lyceum until the death of Alexander the Great in 323. With anti-Macedonian feelings running high in Athens, Aristotle retired to his mother’s birthplace. He died there in 322BCE.
