ARIGAEUM(Ἀριγαῖον), a city of the Paropamisus, in the extreme N. of India (properly beyond its boundary), in the NE. part of the territory of the Aspasii, who inhabited the valley of the Choës ( Kameh). The inhabitants abandoned and burnt it on Alexander's approach, B.C. 327; but the place was so important, as commanding a passage from the valley of the Choës to that of the Guraeus, that Alexander assigned to Craterus the task of its restoration, while he himself pursued the fugitives. (Arrian. Anab. 4.24.) Its site is supposed to have been at Ashiraor Alichurg. [P.S]
