Mosa

• a river in Belgic Gaul, now the Meuse or Maas, Caes. B. G. 4, 9 fin.; 4, 10 init.; Plin. 4, 14, 28, § 100; Tac. A. 2, 6; id. H. 4, 28; 5, 23.

MOSAin Gallia is placed by the Antonine Itin. between Andomatunum ( Langres) and Tullum ( Toul). It is 18 M. P. from Andomatunum to Meosa, which is supposed to be Meuve, situated at a passage over the Maas, and in the line of an old Roman road.

MOSA( Maas), a river of Gallia, which Caesar supposed to rise in the Vosegus ( Vosges) within the limits of the Lingones. ( B. G. 4.10.) This passage of Caesar, in which he speaks of the Mosa in the lower part of its course receiving a part of the Rhine, called Vahalis ( Waal), is very obscure. This matter is discussed in the article BATAVIDio Cassius writes the word in the form Μόσας (44.42); and Ptolemy (Ptol. 2.9.3) has the form Μώσαin the genitive.

Caesar ( B. G. 6.33) says that the Scaldis ( Schelde) flows into the Mosa; a mistake that might easily be made with such knowledge of the coast of Belgium and Holland as he possessed. The only branch of the Mosa which Caesar mentions is the Sabis ( Sambre), which joins the Maason the left bank at Charleroiin Belgium.

The Maas, called Meuseby the French, rises about 48° N. lat. in the Faucilles, which unite the Côte d'Orand the Vosges. The general course of the Maasis north, but it makes several great bends before it reaches Liègein Belgium, from which its course is north as far as Grave, where it turns to the west, and for 80 miles flows nearly parallel to the Waal. The Maasjoins the Waalat Gorcum, and, retaining its name, flows past Rotterdaminto the North Sea. The whole length of the Maasis above 500 miles.

Now the Maas or Meuse; a river in Gallia Belgica, rising in Mount Vogesus and falling into the Vahalis, or west branch of the Rhine.
