That they encamped all but in the city is certain, and may be sufficiently confirmed by the names that the places thereabout yet retain, and the graves and the monuments of those that fell the battle. Both armies being in sight, there was a long pause and doubt on each side which should give the first onset; at last Theseus, having sacrificed to Fear, in obedience to the command of an oracle he had received, gave them battle, in which action a great number of the Amazons were slain. At length, after four months, a peace was concluded between them by the mediation of Hippolyta (for so this historian calls the Amazon whom Theseus married, and not Antiope), though others write that she was slain with a dart by Molpadia, while fighting by Theseus's side, and that the pillar which stands by the temple of Olympian Earth was erected to her honor. Nor is it to be wondered at, that in events of such antiquity, history should be in disorder. This is as much as is worth telling concerning the Amazons.
The celebrated friendship between Theseus and Pirithous is said to have been begun as follows: The fame of the strength and valor of Theseus being spread through Greece, Pirithous was desirous to make a trial and proof of it himself, and to this end seized a herd of oxen which belonged to Theseus, and was driving them away from Marathon, and, when news was brought that Theseus pursued him in arms, he did not fly, but turned back and went to meet him. But as soon as they had viewed one another, each so admired the gracefulness and beauty, and was seized with such a respect for the courage of the other, that they forgot all thoughts of fighting; and Pirithous, first stretching out his hand to Theseus, bade him be judge in this case himself, and promised to submit willingly to any penalty he should impose. But Theseus not only forgave him all, but entreated him to be his friend and brother in arms; and they ratified their friendship by oaths. After this Pirithous married Deidamia, and invited Theseus to the wedding, entreating him to come and see his country, and make acquaintance with the Lapithae; he had at the same time invited the Centaurs to the feast, who, growing hot with wine and beginning to be insolent and wild, the Lapithae took immediate revenge upon them, slaying many of them upon the place, and afterwards, having overcome them in battle, drove the whole race of them out of their country, Theseus all along taking the part of the Lapithae, and fighting on their side.
Theseus was now fifty years old, as Hellanicus states, when he carried off Helen, who was yet too young to be married. Some writers, to take away this accusation of one of the greatest crimes laid to his charge, say that he did not steal away Helen himself, but that Idas and Lynceus brought her to him, and committed her to his charge, and that, therefore, he refused to restore her at the demand of Castor and Pollux; or, indeed, they say her own father, Tyndarus, had sent her to be kept by him, for fear of Enarophorus, the son of Hippocoon, who would have carried her away by force when she was yet a child. But the most probable account, and that which has witnesses on its side, is this:
Theseus and Pirithous went both together to Sparta, and, having seized the young lady as she was dancing in the temple of Diana Orthia, fled away with her. There were presently men in arms sent to pursue, but they followed no farther than to Tegea; and Theseus and Pirithous being now out of danger, having passed through Peloponnesus, made an agreement between themselves, that he to whom the lot should fall should have Helen to his wife, but should be obliged to assist in procuring another for his friend. The lot fell upon Theseus, who conveyed her to Aphidnae, not being yet marriageable, and delivered her to one of his allies, called Aphidnus, and having sent his mother, Aethra, after to take care of her, desired him to keep them so secretly that none might know where they were; which done, to return the same service to his friend Pirithous, he accompanied him in his journey to Epirus, in order to steal away the king of the Molossians' daughter. The king, his own name being Aidoneus, or Pluto, called his wife Proserpina, and his daughter Cora, and a great dog which he kept Cerberus, with whom he ordered all that came as suitors to his daughter to fight, and promised her to him that should overcome the beast. But having been informed that the design of Pirithous and his companion was not to court his daughter, but to force her away, he caused them both to be seized, and threw Pirithous to be torn to pieces by the dog, and put Theseus into prison, and kept him.
