According to Plutarch, Aegeus, king of Athens, having no children, went to Delphi to consult the oracle how that misfortune might be repaired. He was commanded not to approach any woman till he returned to Athens; but the answer was couched in mystic and allegorical terms, and the good king was rather puzzled than enlightened by the reply. He betook himself therefore to Troezene, a small town in Peloponnesus, founded by Pittheus, of the race of Pelops, a man eminent in that day for wisdom and sagacity. He communicated to him the oracle, and besought his interpretation. Something there was in the divine answer which induced Pittheus to draw the Athenian king into an illicit intercourse with his own daughter, Aethra. The princess became with child; and, before his departure from Troezene, Aegeus deposited a sword and a pair of sandals in a cavity concealed by a huge stone [88], and left injunctions with Aethra that, should the fruit of their intercourse prove a male child, and able, when grown up, to remove the stone, she should send him privately to Athens with the sword and sandals in proof of his birth; for Aegeus had a brother named Pallas, who, having a large family of sons, naturally expected, from the failure of the direct line, to possess himself or his children of the Athenian throne; and the king feared, should the secret of his intercourse with Aethra be discovered before the expected child had arrived to sufficient strength to protect himself, that either by treason or assassination the sons of Pallas would despoil the rightful heir of his claim to the royal honours. Aethra gave birth to Theseus, and Pittheus concealed the dishonour of his family by asserting that Neptune, the god most honoured at Troezene, had condescended to be the father of the child:--the gods were very convenient personages in those days. As the boy grew up, he evinced equal strength of body and nobleness of mind; and at length the time arrived when Aethra communicated to him the secret of his birth, and led him to the stone which concealed the tokens of his origin. He easily removed it, and repaired by land to Athens.
