What is "seaxneat"

In Germanic mythology, Seaxnēat (pronounced ) or Saxnōt is the national god of the Saxons. The Old English form Seaxnēat is recorded in the genealogies of the kings of Essex. The Old Saxon form Saxnōt is attested in the Old Saxon Baptismal Vow along with the gods Uuoden (Woden) and Thunaer (Thor).

The genealogy of the kings of Essex originally placed Seaxnēat at its apex. It was subsequently modified to make Seaxnēat son of Woden, with the first king of Essex seven generations later:

Woden, Seaxnēat, Gesecg, Andsecg, Swaeppa, Sigefugel, Bedca, Offa, Æscwine (r. c. 527-587)

The name is interpreted as seax, the war knife eponymous of the tribal name of the Saxons, and (ge)-not, (ge)-nēat as "companion" (cognate with German Genosse "comrade"), resulting in a translation of "sword-companion" (gladii consors, ensifer). This interpretation of the name is due to Jacob Grimm, who identified Saxnot with the god Tiw (Zio) Grimm's view is more recently endorsed by Chaney (1970), but Simek (2007:276) prefers an identification with Fro, following Gabriel Turville-Petre (and invoking Georges Dumézil's trifunctional hypothesis).
