About this time, Menestheus, the son of Peteus, grandson of Orneus, and great-grandson of Erechtheus, the first man that is recorded to have affected popularity and ingratiated himself with the multitude, stirred up and exasperated the most eminent men of the city, who had long borne a secret grudge to Theseus, conceiving that he had robbed them of their several little kingdoms and lordships, and having pent them all up in one city, was using them as his subjects and slaves. He put also the meaner people into commotion, telling them, that, deluded with a mere dream of liberty, though indeed they were deprived of both that and of their proper homes and religious usages, instead of many good and gracious kings of their own, they had given themselves up to be lorded over by a new-comer and a stranger. Whilst he was thus busied in infecting the minds of the citizens, the war that Castor and Pollux brought against Athens came very opportunely to further the sedition he had been promoting, and some say that by his persuasions was wholly the cause of their invading the city. At their first approach, they committed no acts of hostility, but peaceably demanded their sister Helen; but the Athenians returning answer that they neither had her there nor knew where she was disposed of, they prepared to assault the city, when Academus, having, by whatever means, found it out, disclosed to them that she was secretly kept at Aphidnae. For which reason he was both highly honoured during his life by Castor and Pollux, and the Lacedaemonians, when often in aftertimes they made incursions into Attica, and destroyed all the country round about, spared the Academy for the sake of Academus. But Dicaearchus writes that there were two Arcadians in the army of Castor and Pollux, the one called Echedemus, and the other Marathus; from the first that which is now called Academia was then named Echedemia, and the village Marathon had its name from the other, who, to fulfil some oracle, voluntarily offered himself to be made a sacrifice before battle. As soon as they were arrived at Aphidnae, they overcame their enemies in a set battle, and then assaulted and took the town. And here, they say, Alycus, the son of Sciron, was slain, of the party of the Dioscuri (Castor and Pollux), from whom a place in Megara, where he was buried, is called Alycus to this day. And Hereas writes that it was Theseus himself that killed him, in witness of which he cites these verses concerning Alycus-"And Alycus upon Aphidnae's plain, By Theseus in the cause of Helen slain."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 saviours to all mankind beside. And their behviour 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 honour. This their desire they easily obtained, and were adopted by Aphidnus, as Hercules had been by Pylius. They were honoured also like gods, and were called by a new name, Anaces, either from the cessation 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 anything; 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.
Now Hercules, passing by the Molossians, was entertained in his way to Aidoneus the king, who, in conversation, accidentally spoke of the journey of Theseus and Pirithous into his country, of what they had designed to do, and what they were forced to suffer. Hercules was much grieved for the inglorious death of the one and the miserable condition of the other. As for Pirithous, he thought it useless to complain; but begged to have Theseus released for his sake, and obtained that favour from the king. Theseus, being thus set at liberty, returned to Athens, where his friends were not yet wholly suppressed, and dedicated to Hercules all the sacred places which the city had set apart for himself, changing their names from Thesea to Heraclea, four only excepted, as Philochorus writes. And wishing immediately to resume the first place in the commonwealth, and manage the state as before, he soon found himself involved in factions and troubles; those who long had hated him had now added to their hatred contempt; and the minds of the people were so generally corrupted, that, instead of obeying commands with silence, they expected to be flattered into their duty. He had some thoughts to have reduced them by force, but was overpowered by demagogues and factions.
