Though it is not at all probable that Theseus himself was there when both the city and his mother were taken.
Aphidnae being won by Castor and Pollux, and the city of Athens being in consternation, Menestheus persuaded the people to open their gates, and receive them with all manner of friendship, for they were, he told them, at enmity with none but Theseus, who had first injured them, and were benefactors and saviors to all mankind beside. And their behavior gave credit to those promises; for, having made themselves absolute masters of the place, they demanded no more than to be initiated, since they were as nearly related to the city as Hercules was, who had received the same honor. This their desire they easily obtained, and were adopted by Aphidnus, as Hercules had been by Pylius. They were honored also like gods, and were called by a new name, Anaces, either from the cessation (Anokhe) of the war, or from the care they took that none should suffer any injury, though there was so great an army within the walls; for the phrase anakos ekhein is used of those who look to or care for any thing; kings for this reason, perhaps, are called anactes. Others say, that from the appearance of their star in the heavens, they were thus called, for in the Attic dialect this name comes very near the words that signify above.
Some say that Aethra, Theseus's mother, was here taken prisoner, and carried to Lacedaemon, and from thence went away with Helen to Troy, alleging this verse of Homer, to prove that she waited upon Helen,
Aethra of Pittheus born, and large-eyed Clymene.
Others reject this verse as none of Homer's, as they do likewise the whole fable of Munychus, who, the story says, was the son of Demophon and Laodice, born secretly, and brought up by Aethra at Troy. But Ister, in the thirteenth book of his Attic History, gives us an account of Aethra, different yet from all the rest: that Achilles and Patroclus overcame Paris in Thessaly, near the river Sperchius, but that Hector took and plundered the city of the Troezenians, and made Aethra prisoner there. But this seems a groundless tale.
