Dasht-e Kavir
An early description of Media from the end of the 9th century BC to the beginning of the 7th century BC comes from the Assyrians. The southern border of Media, in that period, is named as the Elamite region of Simaški in present-day Lorestan Province. To the west and northwest, Media was bounded by the Zagros Mountains and from the east by the Dasht-e Kavir desert. This region of Media was ruled by the Assyrians and for them the region fell "along the Great Khorasan Road from just east of Harhar to Alwand, and probably beyond." The location of Harhar is suggested to be "the central or eastern" Mahidasht District in Kermanshah Province.
