CIMMERIUM (anc. geog.), a town at the mouth of the Palus Mæotis; from which the Bosphorus Cimmerius is named; that strait which joins the Euxine and the Palus Mæotis. Cimmerii was the name of the people, (Homer); and here stood the Promontorium Cimmerium, (Ptolemy); and hence probably the modern appellation Crim.
