THO´CNIA(Θωκνία, Θώκνεια: Eth. Θωκνεύς), a town of Arcadia in the district Parrhasia, situated upon a height on the river Aminius, which flows into the Helisson, a tributary of the Alpheius. The town was said to have been founded by Thocnus, the son of Lycaon, and was deserted in the time of Pausanias, as its inhabitants had been removed to Megalopolis. It is placed by Leake in the position of Vromoséla. (Paus. 8.3.2, 27.4, 29.5; Steph. B. s. v.;Leake, Morea, vol. 2. p. 293.)
