Apasiacae is the name of a nomadic tribe belonging to the Scythian Massagetae. The Apasiacae lived in between of Oxus and Tanais, in the east coast of the Aral Sea, since Tanais indisputably means here the Jaxartes river, or near the Oxus river in the west of Bactria. The Parthian king Arsaces I fled to these people ca. 230 B.C. from Seleucus II Callinicus.
|“||Arsaces, who had remained closely allied with the nomads to the north, sensed his own weakness in the face of Seleucus's army and fled to the home of the Apasiacae, or “Scythians of the Waters.” Seleucus tried to cross the Jaxartes but, having suffered losses at the hands of the nomads, decided to return to Syria after receiving alarming news from the west. He made peace with Arsaces, who recognized his suzerainty.||”|
