Duende (Spanish and Portuguese)
A duende is a humanoid figure of folklore, with variations from Iberian, Ibero American, and Latin American cultures, comparable to dwarves, gnomes, or leprechauns. In Spanish duende originated as a contraction of the phrase duen(o) de casa, effectively "master of the house", or perhaps derived from some similar mythical being of the Visigoth or Swabian culture given its comparable looks with the “Tomte” of the Swedish language.
The description of the creatures were that of being three to four-foot tall, with heavy shoulders, long arms, brown hair, flat yellowish faces, and long hair down the back of the neck and back. El Duende’s origin was the Iberian peninsula. He was a magical being who either did good or bad. Most notably, he was three-foot tall, wore a big red hat and clothing made from of animal hide.
