Situated on an artificial elevation between the rivers Tigris and Choaspes (perhaps Kerhah, Kharkeh: see also Susa) at the point where they meet, near the Persian Gulf (and the modern frontier between Iraq and Iran). Pliny the Elder describes its foundation by Alexander the Great, who was said to have brought settlers from the royal city of Durine (and some invalid soldiers), but the evidence for this Alexandria is uncertain. A colony, however, was founded by the Seleucid Antiochus IV Epiphanes (175–164 BC) under the name of Antiochia, but after this settlement had been destroyed (not for the first time) by flooding, it was restored by Hyspaosines (c 127–124)—son of a local Arab ruler Sagdodonacus—after whom it took the name of Spasinou. Charax, serving as a port for caravans from the interior until the recession of the Gulf, put an end to this activity.
