The Heracleidae, who thus became practically masters of Peloponnesus, proceeded to distribute its territory among themselves by lot. Argos fell to Temenus, Lacedaemon to Procles and Eurysthenes, the twin sons of Aristodemus; and Messenia to Cresphontes (tradition maintains that Cresphontes cheated in order to obtain Messenia, which had the best land of all.) The fertile district of Elis had been reserved by agreement for Oxylus. The Heracleidae ruled in Lacedaemon until 221 BCE, but disappeared much earlier in the other countries.
