Heraclidae second-generation. Son of Hyllus by Iole (the Oechalian princess Heracles had won by sacking her father Eurytus's city). Father of Aristomachus. Sits at the canonical inheritance-dilution position three generations below Heracles — the divine fraction has dropped to scion-tier (1/8) through the Hyllus-Iole maternal-mortal-line. Per Apollodorus 2.8.2 and Herodotus 6.52, transmitted the Heraclidae return-claim from his father to his son Aristomachus. The line continues: Cleodaeus → Aristomachus → Aristodemus → the Spartan twin-kings Eurysthenes and Procles, founders of the Agiad and Eurypontid royal houses. Cleodaeus himself does not appear to have led an attempted return; the dynastic-claim tradition treats him as the keeper-of-the-claim across the inactive generation between the failed first attempt by Hyllus and the renewed second attempt by Aristomachus.
