MOSA, (anc. geog.) a river of Belgica, rising in mount Vogefus on the borders of the Lingones, and which, after receiving a part of the Rhine called Vabalis, forms the island of the Batavi, and passes off into the sea, at no greater distance than 80 miles: its mouth, which is large and broad, is that which Pliny calls Helius, denoting Lower, according to some German writers. Now called the Masé, or Meuse; rising in Champaign, on the borders of the county of Burgundy, or the Franche Compté, at a village called Meuse, whence the appellation; and running north through Lorraine and Champaign into the Netherlands: it afterwards directs its course north-east, and then west; and joining the Waal, runs to Dort, and falls.
falls into the German sea, a little below the Briel.—According to Baudrand, it twice receives the Waal; by the first junction forming the island Bommel; and again receives it at Woreum, from which place proceeding to Dort, it divides into two branches, which again uniting together form one large mouth discharging itself into the German sea.
