IMAUS, (anc. geog.), the largest mountain of Asia, (Strabo); and a part of Taurus, (Pliny); from which the whole of India runs off into a vast plain, resembling Egypt. It extends far and wide through Scythia, as far as to the Mare Glaciale, dividing it into the Hither or Scythia intra Imaum, and into the Farther or Scythia extra Imaum, (Ptolemy); and also stretching out along the north of India to the eastern ocean, separates it from Scythia. It had various names according to the different countries it runs through: Poëllus thinks it is the Sepbar of Scripture.
