), a navigable river in the north-west of Germany, which was well known to the Romans, from its sources to the point where it empties itself into the Rhine. Its sources are in the interior of Germany, not far from those of the Amisia. (Ems.
) (Vell. 2.105
; Tac. Ann. 1.60
, Hist. v.
22; Pomp. Mela, 3.3.3; Strab. vii. p.291
; D. C. 54.33
.) Strabo (l.c.
) had a very incorrect notion of the course of the Lupia, for he describes it as flowing through the country of the Bructeri Minores, and as discharging its waters, like the Amasia, into the ocean: he, moreover, places it about 600 stadia from the Rhine. Tacitus (Tac. Ann. 2.7
) mentions a Roman fort built on its banks.
