Orchomenos [Arcadia]

 Thucydides (v. 61) the Arcadian Orchomenus Ὀρχομενός ὁ Ἀρκαδικός, to distinguish it from the Boeotian. According to Pausanias  Orchomenus became founder of both the town called Methydrium and of Orchomenus¹. There is a sanctuary of Artemis, surnamed Hymnia, standing on the borders of Orchomenus, near the territory of Mantineia. Artemis Hymnia has been worshipped by all the Arcadians from the most remote period ².
