Perchta or Berchta (English: Bertha), also commonly known as Percht and other variations, was once known as a goddess in Alpine paganism in the Upper German and Austrian regions of the Alps. Her name may mean "the bright one" (Old High German beraht, bereht, from Proto-Germanic *brehtaz) and is probably related to the name Berchtentag, meaning the feast of the Epiphany. Eugen Mogk provides an alternative etymology, attributing the origin of the name Perchta to the Old High German verb pergan, meaning "hidden" or "covered". Perchta is often identified as stemming from the same Germanic goddess as Holda and other female figures of German folklore (see Frija-Frigg). According to Jacob Grimm and Lotte Motz, Perchta is Holda's southern cousin or equivalent, as they both share the role of "guardian of the beasts" and appear during the Twelve Days of Christmas, when they oversee spinning.
Grimm says Perchta or Berchta was known "precisely in those Upper German regions where Holda leaves off, in Swabia, in Alsace, in Switzerland, in Bavaria and Austria."
