In 1841, Georg Waitz discovered two magic charms in a 9-10th century codex in the Cathedral Chapter library of Merseburg, the only surviving literary remnants of Old High German heathenry. In the second Merseburg charm, Woten heals a horse's sprain after other gods have failed.
Variants of this charm, with different gods and saints, survive all over northwestern Europe—the Germanies, Norway, Sweden, Denmark, Scotland, Shetland, and the Hebrides—but a similar spell preserved from Vedic India suggests that it may be ancient of origin indeed.
The charm is of the type known to scholars as a historiola: what linguist Philip A. Shaw defines as “a charm in which a narrative is employed that in some way represents or symbolises the achievement of the desired outcome of the charm” (Shaw 62). Magic-workers have been harnessing the driving power of story to propel their charms for millennia; modern spell-smiths take note!
The Old Craft version of the charm cited below invokes, as one would expect, the god of witches in his person of Wild Rider.
