About this time, Menestheus, the son of Peteus, grandson of Orneus, and great-grandson to 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 both of 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 he 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 honored 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 fulfill 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 Aphidna'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.
