Page "Ásatrú in the United States" Paragraph 6

The term is the Old Norse / Icelandic translation of, a neologism coined in the context of 19th century romantic nationalism, used by Edvard Grieg in his 1870 opera Olaf Trygvason.

The use of the term Ásatrú for Germanic heathenism preceding 19th century revivalist movements is therefore an anachronism.
