2. A son of Cleodemus or Cleodaeus, and greatgrandson of Heracles, was the father of Temenus, Cresphontes, and Aristodemus. He marched into Peloponnesus at the time when Tisamenus, the son of Orestes, ruled over the Peninsula; but his expedition failed as he had misunderstood the oracle, and he fell in battle. (Apollod. 2.8.2; Paus. 2.7.6; Hdt. 6.52.) Another Aristomachus occurs in Paus. 6.21.7.
