Snorri Sturluson,
The Prose Edda
(1916)

He who sits there at the land's-end, to defend the land, is called Surtr; he brandishes a flaming sword, and at the end of the world he shall go forth and harry, and overcome all the gods, and burn all the world with fire; thus is said in Völuspá: Surtr fares from the south with switch-eating flame,— On his sword shimmers the sun of the War-Gods; The rock-crags crash; the fiends are reeling ”
