Was the name of a particular spot in the race-course at Olympia, where horses often became shy and frightened. Superstition was not at a loss to account for this phenomenon, for some said that on that spot Olenius or Dameon had been slain by Cteatus, or because it was the burial-place of Myrtilus (who had frightened the horses of Oenomaus), Alcathous, or Pelops. Pausanias, however, considers Taraxippus to be a surname of Poseidon Hippius. On the isthmus of Corinth, Glaucus, the son of Sisyphus, was believed to be a Taraxippus. (Paus. vi. 20. § 8, &c. ; comp. x. 37. § 4.)
