Korrigans as dwarves and fairiesEdit
The term is used variously by different writers on Breton folklore. Théodore de Villemarqué in Barzaz Breiz uses the term interchangeably with "fairy" and distinguishes them from dwarves ("nains"). In contrast Walter Evans-Wentz in The Fairy Faith in Celtic Countries argued that in the mythology of Morbihan there is no clear distinction between korrigans and nains, "Very often corrigans regarded as nains, equally with all kinds of lutins, are believed to be evil spirits or demons condemned to live here on earth in a penitential state for an indefinite time." They like to dance around fountains. However, they give themselves away when they cannot enumerate the full list of the days of the week (because of the sacredness of the full week).
