Note 106 — THE VOYAGE OF NEARKHOS.

Another form of the name of this river is the Aroatis. It answers to the Zarotis of Pliny, who states that the navigation at its mouth was difficult, except to those well acquainted with it. It formed the boundary between Persis and Susiana. The form Oroatis corresponds to the Zend word aurwat ‘swift.’ It is now called the Tâb.
