"Frau Holle" (ˌfraʊ_ˈhɒl ; also known as "Mother Holle", "Mother Hulda" or "Old Mother Frost") is a German fairy tale collected by the Brothers Grimm in Children's and Household Tales in 1812 (KHM 24). It is of Aarne-Thompson type 480. Frau Holle (also known in various regions as Holla, Holda, Perchta, Berchta, Berta, or Bertha) was initially a pre-Christian female legendary figure who survived in popular belief well into the 19th century. The name may be cognate of the Scandinavian creature known as the Hulder. Jacob Grimm made an attempt to establish her as a Germanic goddess. The name is thought to originate from German huld ("gracious, friendly, sympathetic, grateful" found in hold sein, huldigen), Middle High German hulde, Old High German huldī ("friendliness"). Cognate with Danish and Swedish huld ("fair, kindly, gracious") or 'hyld' ("secret, hidden"), Icelandic hollur ("faithful, dedicated, loyal"), Middle English hold, holde, Old English hold ("gracious, friendly, kind, favorable, true, faithful, loyal, devout, acceptable, pleasant"), from Proto-Germanic hulþaz ("favourable, gracious, loyal"), from Proto-Indo-European *kel- ("to tend, incline, bend, tip"). The name Hludana is found in five Latin inscriptions: three from the lower Rhine (Corpus Inscriptionum Latinarum XIII 8611, 8723, 8661), one from Münstereifel () and one from Beetgum, Frisia () all dating from 197 AD-235 AD. Many attempts have been made to interpret this name. Marija Gimbutas names Hulda (or Holda, Holla, Holle) as having originally been an ancient Germanic supreme goddess who predates most of the Germanic pantheon, including deities such as Odin, Thor, Freya, and Loki, continuing traditions of pre-Indo-European Neolithic Europe. As Christianity slowly replaced Germanic paganism during the Early Middle Ages, many of the old customs were gradually lost or assimilated into Christian tradition. By the end of the High Middle Ages, Germanic paganism was almost completely marginalized and blended into rural folklore, in which the character of Frau Hulda eventually survived.
