A son of Tisamenus, grandson of Thersander, and great-grandson of Polyneices. He is called the father of Theras and Argeia, by the latter of whom Aristodemus became the father of Eurysthenes and Procles. He was a native of Thebes, where he had succeeded his father as king, but at the command of an oracle he went to Peloponnesus and joined the Dorians.
