The last of these attempts resulted in the " Dorian conquest " of the "Achaeans " and " Ionians " of Peloponnese, and in the assignment of Argolis, Laconia and Messenia to the Heracleid leaders, Temenus, Aristodemus and Cresphontes respectively; of Elis to their Aetolian allies; and of the north coast to the remnants of the conquered Achaeans.
At last, Temenus, Cresphontes and Aristodemus, the sons of Aristomachus, complained to the oracle that its instructions had proved fatal to those who had followed them.
The oracle, being again consulted by Temenus, bade him offer an expiatory sacrifice and banish the murderer for ten years, and look out for a man with three eyes to act as guide.
On his way back to Naupactus, Temenus fell in with Oxylus, an Aetolian, who had lost one eye, riding on a horse (thus making up the three eyes) and immediately pressed him into his service.
Argos fell to Temenus, Lacedaemon to Procles and Eurysthenes, the twin sons of Aristodemus; and Messene to Cresphontes.
