“The name of Imaüs was, in the first instance, applied by the Greek geographers to the Hindú-Kúsh and to the chain parallel to the equator, to which the name of Himâlaya is usually given at the present day. The name was gradually extended to the intersection running north and south, the meridian axis of Central Asia, or the Bolor range. The divisions of Asia into ‘intra et extra Imaum,’ were unknown to Strabo and Pliny, though the latter describes the knot of mountains formed by the intersections of the Himâlaya, the Hindú-Kúsh, and Bolor, by the expression ‘quorum (Montes Emodi) promontorium Imaüs vocatur.’ The Bolor chain has been for ages, with one or two exceptions, the boundary between the empires of China and Turkestan.”—Dr. Smith’s Dictionary of Ancient Geography.
