The Gerrhaeans also traded with East Africa and China through India. In their activity they act as the warehouse for everything from Asia and Europe ... seem more prosperous than the Sabaeans. (Groom, p. 71). Trade through Gerrha was heavy in the time of Antioch; Strabo writes: the leading people of this time were the Gerrhaeans, and the Arab tribe whose capital lay on the mainland just opposite Bahrain made ... enormous incomes by trading the precious wares of Arabia and India to the mouths of the Euphrates and Tigris, along the upper course of the rivers by ancient caravan routes to the coast of Syria and Phoenicia even as far as Delos and the Aegean Sea. (Bibby, p. 113).
