Naharvali
Eth. Naharvali one of the most powerful tribes of the Lygii, in the north-east of Germany. Tacitus (Germ. 43) relates that the country inhabited by them (probably about the Vistula) contained an ancient and much revered grove, presided over by a priest in female attire. It was sacred to twin gods called Alcis, whom Tacitus identifies with Castor and Pollux. (Latham on Tac. Germ. l.c.; Sprengel, Erlaüter. zu Tac. Germ. p. 140.)
