the island of the Batavi, was bounded, according to Tacitus, by the ocean, the Rhine, and the Vahalis, now the Waal. Caesar extends it to the Mosa, or Meuse; but Pliny's description coincides with that of Tacitus. This island was, however, of greater extent in the time of Tacitus than in that of Caesar; for, by a new canal, Drusus, the father of Germanicus, conveyed the waters of the Rhine into the ocean, a considerable way north of the former mouth of that river. The Batavi were a branch of the Catti, who, having been expelled their country in consequence of a domestic sedition, occupied the extremity of the coast of Gaul, at that time uninhabited, together with this island situated among shoals. The name of Batavi they carried with them from Germany. The modern name of this island is Betu or Betan.
