The Achelous (Greek: Αχελώος, Ancient Greek: Ἀχελῷος Akhelôios), also Acheloos, is a river in Epirus, western Greece. It is 220 km (137 mi) long.[1][2] It formed the boundary between Acarnania and Aetolia of antiquity. It empties into the Ionian Sea. In ancient times its spirit was venerated as the river god Achelous.
Herodotus, taking notice of the shoreline-transforming power of the Acheloos River, even compared it to the Nile in this respect:
- 'There are other rivers as well which, though not as large as the Nile, have had substantial results. In particular (although I could name others), there is the Achelous, which flows through Acarnania into the sea and has already turned half the Echinades islands into mainland.' (2.10, trans. Waterfield)
It is said to have been called more anciently Thoas, Axenus and Thestius.[3]
