Helisson
Helisson was a town in ancient Arcadia, Greece. It was situated in the district Maenalia, situated on Mount Maenalus near the territory of Mantineia, near the source of the river Helisson, a tributary of the Alpheius. According to Greek mythology, the town was founded by Helisson, a son of Lycaon.
The town was taken by the Lacedaemonians in one of their wars with the Arcadians, 352 BCE; but most of its inhabitants had been previously removed to Megalopolis upon the foundation of the latter city in 371 BCE. There was a temple of Poseidon with a statue of the god. Pausanias found the head of the statue still remaining. The Elisphasii mentioned by Polybius are conjectured by some writers to be a corrupt form of Helissontii.
Its site is tentatively located south the modern Piana.
