Note 210 — Chapter IX · —Description of India
Reading edition
No satisfactory identification of this river has as yet, so far as I am aware, been proposed. The river called by Arrian (iv. 6) the Erymandros, and by Polybios the Erymanthus, and now known as the Helmund, has a name pretty similar, but it does not discharge into the sea. It enters the inland lake called Zarah, in the province of Seistan in Afghanistan. According to Arrian it disappears in the sands.
