Hypana

Hypana (Ancient Greek: Ὕπανα)[1] or Hypaneia (Ὑπάνεια)[2] was a town in the interior of Triphylia in ancient Elis. It was taken by Philip V of Macedon in the Social War.[3] Its inhabitants had been transferred to Elis when Strabo wrote. Hypana is mentioned along with Typaneae near the rivers Dalion and Acheron, tributaries of Alpheus.[4] Both these towns must have been situated in the mountains of Triphylia.

Most modern scholars identify its location with a site near the modern town of Platiana,[5][6][7] though other writers disagree, and propose other locations.[8]

It has been suggested by Juan José Torres Esbarranch that Hypana is sited near a locality currently called Gryllos, which used to be called Mundritza (Juan José Torres Esbarranch (2001). Estrabón, Geografía libros VIII-X (in Spanish). Madrid: Gredos. p. 59, n. 160. ISBN 84-249-2298-0.).
