Aristotle, son of Nicomachus and Phaestis, was a native of Stagira. His father, Nicomachus, as Hermippus relates in his book On Aristotle, traced his descent from Nicomachus who was the son of Machaon and grandson of Asclepius; and he resided with Amyntas, the king of Macedon, in the capacity of physician and friend. Aristotle was Plato’s most genuine disciple; he spoke with a lisp, as we learn from Timotheus the Athenian in his book On Lives; further, his calves were slender (so they say), his eyes small, and he was conspicuous by his attire, his rings, and the cut of his hair. According to Timaeus, he had a son by Herpyllis, his concubine, who was also called Nicomachus.
He seceded from the Academy while Plato was still alive. Hence the remark attributed to the latter: Aristotle spurns me, as colts kick out at the mother who bore them.[*](Cf. Aelian, V.H. iv. 9.) Hermippus in his Lives mentions that he was absent as Athenian envoy at the court of Philip when Xenocrates became head of the Academy, and that on his return, when he saw the school under a new head, he made choice of a public walk in the Lyceum where he would walk
In time the circle about him grew larger; he then sat down to lecture, remarking[*](Eur. Philoct. Frag. 785 Dind., 796 Nauck2.):

Afterwards, however, he departed to Hermias the eunuch, who was tyrant of Atarneus, and there is one story that he was on very affectionate terms with Hermias; according to another, Hermias bound him by ties of kinship, giving him his daughter or his niece in marriage, and so Demetrius of Magnesia narrates in his work on Poets and Writers of the Same Name. The same author tells us that Hermias had been the slave of Eubulus, and that he was of Bithynian origin and had murdered his master. Aristippus in his first book On the Luxury of the Ancients says that Aristotle fell in love with a concubine of Hermias,
