Strabo, Geography

Apollodorus says that in the interior of Acarnania there is a people called Erysichaeans, who are mentioned by Alcman:“nor yet an Erysichaean nor shepherd, but from the heights of Sardeis.
”¹ But Olenus, which Homer mentions in the Aetolian catalogue, was in Aetolia, though only traces of it are left, near Pleuron at the foot of Aracynthus. Near it, also, was Lysimachia; this, too, has disappeared; it was situated by the lake now called Lysimachia, in earlier times Hydra, between Pleuron and the city Arsinoe. In earlier times Arsinoe was only a village, and was called Conopa, but it was first founded as a city by Arsinoe, who was both wife and sister of Ptolemy the Second;² it was rather happily situated at the ford across the Acheloüs. Pylene³ has also suffered a fate similar to that of Olenus. When the poet calls Calydon both "steep"⁴ and "rocky,"⁵ one should interpret him as referring to the country; for, as I have said,⁶ they divided the country into two parts and assigned the mountainous part, or Epictetus,⁷ to Calydon and the level country to Pleuron.
