Further studies by Hans-Jörg Uther and Waldemar Liungman confirm Thompson's assessment, since the tale can be found in Norway (with the title Kongsdatteren i haugen, or "The King's Daughter in the Mound"), Iceland, Sweden and Finland, as well as in northwest Germany.
Stith Thompson claimed that the tale type is "essentially Scandinavian", since most of its variants are collected there.
