Pittheus, therefore, taking advantage from the obscurity of the oracle, prevailed upon him, it is uncertain whether by persuasion or deceit, to lie with his daughter Aethra. Aegeus afterwards, knowing her whom he had lain with to be Pittheus's daughter, and suspecting her to be with child by him, left a sword and a pair of shoes, hiding them under a great stone that had a hollow in it exactly fitting them; and went away making her only privy to it, and commanding her, if she brought forth a son who, when he came to man's estate, should be able to lift up the stone and take away what he had left there, she should send him away to him with those things with all secrecy, and with injunctions to him as much as possible to conceal his journey from every one; for he greatly feared the Pallantidae, who were continually mutinying against him, and despised him for his want of children, they themselves being fifty brothers, all sons of Pallas. When Aethra was delivered of a son, some say that he was immediately named Theseus, from the tokens which his father had put @ under the stone; others that he received his name afterwards at Athens, when Aegeus acknowledged him for his son. He was brought up under his grandfather Pittheus, and had a tutor and attendant set over him named Connidas, to whom the Athenians, even to this time, the day before the feast that is dedicated to Theseus, sacrifice a ram, giving this honor to his memory upon much juster grounds than to Silanio and Parrhasius, for making pictures and statues of Theseus. There being then a custom for the Grecian youth, upon their first coming to man's estate, to go to Delphi and offer first-fruits of their hair to the god, Theseus also went thither, and a place there to this day is yet named Thesea, as it is said, from him. He clipped only the fore part of his head, as Homer says the Abantes did.% And this sort of tonsure was from him named Theseis. The Abantes first used it, not in imitation of the Arabians, as some imagine, nor of the Mysians, but because they were a warlike people, and used to close fighting, and above all other nations accustomed to engage hand to hand; as Archilochus testifies in these verses: -- Slings shall not whirl, nor many arrows fly, When on the plain the battle joins; but swords, Man against man, the deadly conflict try, As is the practice of Euboea's lords Skilled with the spear.-- Therefore that they might not give their enemies a hold by their hair, they cut it in this manner. They write also that this was the reason why Alexander gave command to his captains that all the beards of the Macedonians should be shaved, as being the readiest hold for an enemy.
