MADIAN, in Ancient Geography, a town of Arabia Petrea, near the Arnon; so called from one of the sons of Abraham by Keturah, in ruins in Jerome's time. Jerome mentions another MADIAN, or MIDIAN, beyond Arabia, in the desert, to the south of the Red sea; and hence Madianites, and Madianitee, the people; and Madiana Regio, the country.
