Mannus

Mannus, according to the Roman writer Tacitus, was a figure in the creation myths of the Germanic tribes. Tacitus is the only source of these myths. Tacitus wrote that Mannus was the son of Tuisto and the progenitor of the three Germanic tribes Ingaevones, Herminones and Istvaeones. In discussing the German tribes, Tacitus wrote: "In ancient lays, their only type of historical tradition, they celebrate Tuisto, a god brought forth from the earth. They attribute to him a son, Mannus, the source and founder of their people, and to Mannus three sons, from whose names those nearest the ocean are called Ingvaeones, those in the middle Herminones, and the rest Istvaeones. Some people, inasmuch as antiquity gives free rein to speculation, maintain that there were more sons born from the god and hence more tribal designations—Marsi, Gambrivii, Suebi, and Vandilii—and that those names are genuine and ancient."

Several authors consider the name Mannus in Tacitus's work to stem from an Indo-European root.

The Latinized name Mannus is evidently of some relation to Proto-Germanic mannaz, 'man'.

Mannus again became popular in literature in the 16th century, after works published by Annius de Viterbo and Johannes Aventinus purported to list him as a primeval king over Germany and Sarmatia.

In the 19th century, F. Nork wrote that the names of the three sons of Mannus can be extrapolated as Ingui, Irmin, and Istaev or Iscio. A few scholars like Ralph T. H. Griffith have expressed a connection between Mannus and the names of other ancient founder-kings, such as Minos of Greek mythology, and Manu of Hindu tradition.

Guido von List incorporated the myth of Mannus and his sons into his occult practice, which were later adopted into Nazi occult beliefs.
