Concerning his voyage into the Euxine Sea, Philochorus and some others write that he made it with Hercules, offering him his service in the war against the Amazons, and had Antiope given him for the reward of his valor; but the greater number, of whom are Pherecides, Hellanicus, and Herodorus, with a navy under his own command, and took the Amazon prisoner,--the more probable story, for we do not read that any other, of all those that accompanied him in this action, took any Amazon prisoner. Bion adds, that, to take her, he had to use deceit and fly away; for the Amazons, he says, being naturally lovers of men, were so far from avoiding Theseus when he touched upon their coasts, that they sent him presents to his ship; but he, having invited Antiope, who brought them, to come aboard, immediately set sail and carried her away. An author named Menecrates, that wrote the History of Nicaea in Bithynia, adds, that Theseus, having Antiope aboard his vessel, cruised for some time about those coasts, and that there were in the same ship three young men of Athens, that accompanied him in his voyage, all brothers, whose names were Euneos, Thoas, and Soloon. The last of these fell desperately in love with Antiope; and escaping the notice of the rest, revealed the secret only to one of his most intimate acquaintance, and employed him to disclose his passion to Antiope. She rejected his pretences with a very positive denial, yet treated the matter with much gentleness and discretion, and made no complaint to Theseus of anything that had happened; but Soloon, the thing being desperate, leaped into a river near the seaside and drowned himself. As soon as Theseus was aquainted with his death, and his unhappy love that was the cause of it, he was extremely distressed, and, in the height of his grief, an oracle which he had formerly received at Delphi came into his mind; for he had been commanded by the priestess of Apollo Pythius, that, wherever in a strange land he was most sorrowful and under the greatest affliction, he should build a city there, and leave some of his followers to be governors of the place. For this cause he there founded a city, which he called, from the name of Apollo, Pythopolis, and, in honor of the unfortunate youth, he named the river that runs by it Soloon, and left the two surviving brothers intrusted with the care of the government and laws, joining with them Hermus, one of the nobility of Athens, from whom a place in the city is called the House of Hermus; though by an error in the accent it has been taken for the House of Hermes, or Mercury, and the honor that was designed to the hero, transferred to the god.
