In Marathon is a spring called Macaria with the following legend. When Heracles left Tiryns
, fleeing from Eurystheus, he went to live with his friend Ceyx, who was king of Trachis
. But when Heracles departed this life Eurystheus demanded his children; whereupon the king of Trachis
sent them to Athens
, saying that he was weak but Theseus had power enough to succor them. The arrival of the children as suppliants caused for the first time war between Peloponnesians and Athenians, Theseus refusing to give up the refugees at the demand of Eurystheus. The story says that an oracle was given the Athenians that one of the children of Heracles must die a voluntary death, or else victory could not be theirs. Thereupon Macaria, daughter of Deianeira and Heracles, slew herself and gave to the Athenians victory in the war and to the spring her own name.
