in Ancient Geography, a river of Lusitania, called otherwise Limaes, Limaeas, Limias, and Lethe, or the river of oblivion: the boundary of the expedition of Decimus Brutus. The soldiers out of superstition refusing to cross, he snatched an ensign out of the hands of the bearer, and passed over, by which his army was encouraged to follow (Livy.) He was the first Roman who ever proceeded so far, and ventured to cross. The reason of the appellation according to Strabo is, that in a military expedition a sedition arising between the Celtici and Turduli, after crossing that river, in which the general was slain, they remained dispersed there; and from this circumstance it came to be called the river of Lethe or oblivion. Now called El Lima, in Portugal, running westward into the Atlantic, to the south of the Minho.
