Book 5
8.3
Augeas too held them, and likewise Heracles, the son of Amphitryon, after the conquest of Elis. The victors crowned by Heracles include Iolaus, who won with the mares of Heracles. So of old a competitor was permitted to compete with mares which were not his own. Homer,Hom. Il. 23.295 at any rate, in the games held in honor of Patroclus, has told how Menelaus drove a pair of which one was Aetha, a mare of Agamemnon, while the other was his own horse.
8.4
Moreover, Iolaus used to be charioteer to Heracles. So Iolaus won the chariot-race, and Iasius, an Arcadian, the horse-race; while of the sons of Tyndareus one won the foot-race and Polydeuces the boxing-match. Of Heracles himself it is said that he won victories at wrestling and the pancratium.
8.5
After the reign of Oxylus, who also celebrated the games, the Olympic festival was discontinued until the reign of Iphitus. When Iphitus, as I have already related,Paus. 5.4.5 renewed the games, men had by this time forgotten the ancient tradition, the memory of which revived bit by bit, and as it revived they made additions to the games.
