Aras

Chambers's Encyclopaedia, Volume 1: A to Beaufort, p. 373

Aras (the ancient Araxes), the chief river of Armenia, formed by the junction of the Bingol-Su and the Kaleh-Su, flowing E., SE., and NE., and uniting its waters with those of the Kur (ancient Cyrus) after a course of about 500 miles. It joins the Kur, which descends from the Caucasus through Georgia, about 75 miles from its mouth. Their united waters turn suddenly to the south, and fall by three mouths into the Gulf of Kizilgatch, in the Caspian Sea.
