Acacesium or Akakesion (Greek, Ancient (to 1453);: Ἀκακήσιον),[1] was a town of ancient Arcadia in the district of Parrhasia, at the foot of a hill of the same name, and 36 stadia on the road from Megalopolis to Phigalea. It is said to have been founded by Acacus, son of Lycaon; and according to some traditions, Hermes was brought up at this place by Acacus, and hence derived the surname of Acacesius. Upon the hill there was a statue in stone, in the time of Pausanias, of Hermes Acacesius; and four stadia from the town was a celebrated temple of Despoena.[2] This temple probably stood on the hill, on which are now the remains of the church of St Elias.[3]
Its site is located near modern Daseiai.
