Till Eulenspiegel
The literal translation of the High German name gives “owl mirror”, two symbols that identify Till Eulenspiegel in crude popular woodcuts (illustration). However, the original Low German is believed to be ul’n Spegel, meaning “wipe the arse”. In the eighteenth century, German satirists adopted episodes for social satire, and in the nineteenth and early twentieth-century versions of the tales are bowdlerized, to render them fit for children, who had come to be considered their chief natural audience, by expurgating their many references to human excrement.[9]
