Ballad versions There are generally agreed to be six primary versions of this ballad, titled A, B, C, D, E, and F, with C having four derived versions (Cabcd) and F having eight derived versions (Fabcdefgh). Version A is the only pre-1800s version of the ballad that refers to the transformed bird as "valravn," and it only does so in the sentences "vilde valle ravn," "vilden vallen ravn" () and "vilden valravn" (). Versions B and D were written down in Svanings Håndskrift (), circa 1580, by unnamed assistants hired by historian Hans Svaning. In these versions the bird is referred to as "Volffuer vilde ravn" and "villen vallen-ravn," respectively, with "Volffuer" being an old Danish male name. ==Folklore==
