A nisse, tomte, or tomtenisse (Sweden) (Swedish pronunciation: [²tɔmːtɛ]), nisse ( Denmark and Norway) (Danish pronunciation: [ˈnesə] or Norwegian pronunciation: [²nisːe], Danish plural nisser) or tonttu (Finland) is a mythological creature from Scandinavian folklore today typically associated with the winter solstice and the Christmas season. It is generally described as being no taller than 90 cm (35 in), having a long white beard, and wearing a conical or knit cap in red or some other bright colour. They often have an appearance somewhat similar to that of a garden gnome (which are also called trädgårdstomte in Swedish, havenisse in Danish and hagenisse in Norwegian).
The nisse is one of the most familiar creatures of Scandinavian folklore, and he has appeared in many works of Scandinavian literature. With the romanticisation and collection of folklore during the 19th century, the nisse would gain popularity. In the English editions of the fairy tales of H. C. Andersen the word nisse has been inaccurately translated as goblin (a more accurate translation is brownie or hob).
The nisse/tomte is an echo of ancient ancestral cult. He was sometimes seen as the farmer who cleared the forest to build the farm and who in pre-Christian times would have been buried on the farm in a mound. He was sometimes referred to as the haugkall or haugebonde, from the Old Norse haugr meaning mound. Other names are tuftekall, tomtegubbe, all names connecting the being to the origins of the farm (the building ground) or a burial mound. It was thought that the nisse was a more generalized spirits of previous generations at the homestead, and there are references to them following the family/clan, when they are moving.
