Glaucus (son of Sisyphus)

In Greek and Roman mythology, Glaucus (Greek: Γλαῦκος, Glaukos) was a son of Sisyphus whose main myth involved his violent death as the result of his horsemanship. He was a king of Corinth and the subject of a lost tragedy by Aeschylus, Glaucus Potnieus (Glaucus at Potniae), fragments of which are contained in an Oxyrhynchus Papyrus.

Glaucus took part in the funeral games organized in honor of Pelias by his son Acastus, the famous Athla epi Pelia in which some of the foremost heroes of Greece competed, including the Argonauts. Glaucus lost to Iolaus in the chariot race. A fragment from Aeschylus's tragedy has sometimes been taken to mean that Glaucus died in a chariot accident on the way home, but it seems more probable that the accident occurred during the race. According to Pausanias, Glaucus haunted the Isthmian Games as a form of Taraxippus, because he was killed by his horses during the funeral games.

There are two main traditions concerning the death of Glaucus. In one, he feeds his mares on human flesh in order to make them fierce in battle, but at the games he has no supply for them, and they turn on their master and devour him instead.Servius, however, regards Glaucus as a doublet of Hippolytus: he offended the goddess Aphrodite (Venus) either by keeping his mares from mating in order to preserve their speed, or by scorning her in general. The goddess then brings retribution upon him through his horses. In other sources, the mares are driven into their man-killing frenzy by consuming either an herb in their Boeotian pasture at Potniae or water from a toxic well.Gilbert Murray saw Hippolytus, Glaucus and their ilk as undergoing sparagmos as vegetation deities.
