The ancient Arab name for the Caspian Sea was Bahr-e Gulan, at its southern shore Golestan named for Aram’s son Hul (a grandson of Shem, see Genesis 10), and the Persians called it the Darya-e Khazar, for a son of Togarmah (who was a grandson of Japheth)), then later the Greeks beginning with Strabo named it for a tribe in Golestan called the Caspi, of the Mardos river valley.
