A´ROSIS
A´ROSIS (
Ἄροσις, Arrian,
Ind. 39), a river which flowed into the Persian Gulf, forming the boundary of Susiana and Persis.
It is the same as the Oroatis (
Ὀροάτις; in Zend.
Aurwat, “swift” ) of Strabo (xv. pp. 727, 729), and of Ptolemy (
6.4.1). Arrian and Strabo both state that it was the chief river in those parts.
It answers to the Zarotis of Pliny (
6.23. s. 26), “ostio difficilis nisi peritis.” It is now called the
Tab. (
Geogr. Nub. p. 123; Otter, vol. ii. p. 49.) Cellarius (3.100.9) has conjectured that the Arosis of Arrian, the Rogomanis of Ptolemy (
6.4.2), and Amm. Marc. (23.6), and the Persian Araxes (
Strab. xv. p.729), are different names of one and the same river : but this does not seem to be the case.
