Stith Thompson suggested the tale type ATU 850 originated from genuine European oral folklore, since an ancient literary version is not attested. He also stated that variants are "told all over Europe". This geographical analysis seems to have been confirmed by scholars
Richard Dorson and
Kurt Ranke, who claimed that the tale type was "narrated throughout Europe as well as in North and South America".
Slavic-speaking area August Leskien claimed that this "Märchenkreis" is very widespread in Slavic tradition, with the same plot: the princess sees the dancing animals (sheep, pigs, etc.) of a peasant who plays a musical instrument (flute, violin, etc.) and is interested in buying the animals, in exchange for showing her birthmarks.
