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. (Germania, chapter 2)
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.
