traveler who visited several generations of early the wandering Goths ‒ who started to regard him as a god, later influencing other Germanic peoples. The Day of the Giants (1959) by Lester del Rey tells the tale of Ragnarok happening in a near future science fiction setting, with an erstwhile engineer arming the Norse Gods with modern weaponry. The Argentinian writer Jorge Luis Borges have mentioned various Norse gods along his life work, as he did in the short story Ulrica and the poem titled A wolf (Un Lobo). Also, he was buried in Geneva and his gravestone has inscriptions written in old English and Old Norse. The figures drawn on it were inspired from the Völsunga Saga and the Anglo-Saxon Battle of Maldon. J. R. R.

As that work became popular, elements of its fantasy world moved steadily into popular perceptions of the fantasy genre.

Children's writer Alan Garner borrowed many Norse concepts, such as the tale of Freyja's necklace Brísingamen and the hard winter (Fimbulwinter) which portends the end of the world, Ragnarok in his classic story, The Weirdstone of Brisingamen (1960).

Several other characters from Norse mythology such as Siegfried, Brunhilde, Baldur and Sigyn are mentioned as well (though not all by name).

Douglas Adams referenced to the Norse god, Thor in his book Life, the Universe and Everything (1982). Odin and Thor also appear in The Long Dark Tea-Time of the Soul, one of two novels by Adams about protagonist Dirk Gently. In the subsequent, sixth, Hitchhiker's Guide to the Galaxy novel (And Another Thing), by Eoin Colfer, Thor appears in a prominent role.
