in Ancient Geography, a small river of Asia Minor, rising in Mount Ida in the Troas, and flowing northwards into the Propontis, which it enters opposite the island of Proconnesus. Its historical interest is greater than its geographical interest; for it was the scene of two very famous battles, the first gained by Alexander over the Persians in 334 B.C., and the second by Lucullus over Mithridates in 74 B.C. The Granicus is probably represented by the modern Kodsha-su, though some writers identify it with the Dimoticos.
