BASA or BASAG, a place on the south coast of Arabia, mentioned only by Pliny (Plin. Nat. 6.28. s. 32), perhaps identical with Ptolemy's Abisa or Abissagi, a city situated on the Gulf of Salachitae, near the Straits of the Persian Gulf. This ancient site Forster identifies with Abissa, a town at the eastern extremity of the Gulf of Bassas, between Harmin and Ras-al-Had, under the Palheiros Mountains, which he conceives to be the Didymi montes of Ptolemy. (Arabia, vol. ii. pp. 182, 235.)
