Mannus according to Tacitus, the name given by the Germans to the son of the earth-born god Tuisco. From his three sons they derived their three great tribes, the Ingavones, the Iskavones, and the Herminones. Mannus belongs, not to the Teutonic people alone, but to the great mythus of the origin of the human race, common to the whole Aryan family, and, like the Hindu Mannu or Manus, stands forth as the progenitor of the inhabitants of earth endowed with reason. The name is derived from the Aryan root mian, to think. Compare Wackernagel, in Haupt's Zeitschrift für Deutsches Alterthum, vol. vi.
