Aristodemus


In Greek mythology, Aristodemus was one of the Heracleidae, son of Aristomachus and brother of Cresphontes and Temenus. He was a great-great-grandson of Heracles and helped lead the fifth and final attack on Mycenae in the Peloponnesus.
Aristodemus and his brothers complained to the Oracle that its instructions had proved fatal to those who had followed them. They received the answer that by the "third fruit" the "third generation" was meant, and that the "narrow passage" was not the isthmus of Corinth, but the straits of Rhium. They accordingly built a fleet at Naupactus, but before they set sail, Aristodemus was struck by lightning and the fleet destroyed, because one of the Heraclidae had slain an Acarnanian soothsayer.
His brothers were later able to conquer the Peloponessus.
By his wife Argia, daughter of King Autesion of Thebes, he was the father of twin Kings Eurysthenes and Procles, the ancestors of the two royal houses of Sparta.
