Glaucus (son of Sisyphus)

In Greek and Roman mythology, Glaucus (/ˈɡlɔːkəs/; Ancient Greek: Γλαῦκος Glaukos means "greyish blue" or "bluish green" and "glimmering"), usually surnamed as Potnieus, was a son of Sisyphus whose main myth involved his violent death as the result of his horsemanship. He was the king of the Boeotian city of Potniae or sometimes of Corinth. Glaucus was the subject of a lost tragedy by Aeschylus, Glaucus Potnieus (Glaucus at Potniae), fragments of which are contained in an Oxyrhynchus Papyrus.
