Aria Lacus

ARIA LACUS (ἡ Ἀρία λιμνὴ, Ptol. 6.14.2), a lake on the NW. boundary of Drangiana and the Desert of Kirman,--now called Zarah or Zerrah. It has been placed by Ptolemy too far to the N., and has been connected by him with the river Arius. M. Burnouf (Comm. sur le Yaçna, p. xcvii.) derives its name and that of the province to which it properly belongs, from a Zend word, Zarayo (a lake). It may have been called the Arian Lake, as adjoining the wider limits of Ariana.
