Philostratus the Younger, imagines 9
The man mounted on a four-horse chariot who is setting out to drive across the mainland, wearing an upright tiara and Lydian dress, is Pelops, I believe, a “bold charioteer” it is fair to call him. For he once guided this chariot even across the sea, doubtless because it was the gift of Poseidon, speeding over the back of the clam sea on the very edge of the wheel and keeping the axle unwetted. His flashing eye and erect head attest his alertness of mind, and his haughty brow indicates that he youth despises Oenomaüs. For he is proud of his horses, since they hold their necks high, are broad of nostril, hollow of hoof, dark-eyed and alert, and they lift their abundant manes above their dark necks as is the manner of sea-horses. Near them stands Hippodameia; she colours her cheek with a modest blush, wears the raiment of a bride, and gazes with eyes that choose rather the stranger’s part. For she loved him and she loathes the parent who takes pride in such spoils as indeed you see – these heads which have been suspended one after another from the gateway, and the time which has elapsed since each of the men perished has given them each a distinctive appearance. For Oenomaüs slew those who came to sue for his daughter’s hand and he delights in the tokens of their death. But their shades hovering over the place lament each the contest in which it took part as they descant upon the covenant of marriage; for Pelops, they recount, has made a covenant, promising that henceforth the girl will be free from the curse. And Myrtilus is witness to the covenant of the twain. Oenomaüs is not far away; nay, his chariot is ready, and on the seat is laid the spear with which to slay the youth when he overtakes him; and he is hurriedly sacrificing to his father Ares, this man of savage aspect and with murder in his eye; and he urges Myrtilus on. But Eros, said of mien, is cutting the axle of the chariot, making clear two things: that the girl in love with her lover is conspiring against her father, and that the future which is in stores for the house of Pelops comes from the Fates.
