Some forty stades from Dyme
the river Peirus flows down into the sea; on the Peirus once stood the Achaean city of Olenus
. The poets who have sung of Heracles and his labours have found a favorite subject in Dexamenus, king of Olenus
, and the entertainment Heracles received at his court. That Olenus
was from the beginning a small town I find confirmed in an elegiac poem composed by Hermesianax about Eurytion the Centaur. In course of time, it is said, the inhabitants, owing to their weakness, left Olenus
and migrated to Peirae and Euryteiae.
