The Douen is an entity from Trinidad and Tobago folklore spelt Dwen in Saint Lucian folklore. Their most recognized characteristic is their feet are said to be backwards, with the heel facing the front and the knees are backwards also being faceless. If they hear a child's name, then they can call to the child in a parent's voice and try to lure the child into the forest. They wear a big, floppy straw hat to hide the fact that they have no face except for a small mouth to speak with. Largely mischievous, they play pranks on people, raid gardens, and seem to enjoy leading children astray until they are thoroughly lost in the woods.
Trinidad and Tobago folklore is primarily of African foundation, with French, Spanish, and English influences. Religious or semi-religious cults of African origin have undeniably contributed much to the Island's folklore. Many of the supernatural folklore characters are identical with those of African deities. It is exceedingly complicated to draw a line between the stern religious elements and what may be described as traditions. Nevertheless, in the African tradition, stories were meant to instill values in the children.[1]
Based on the description of Trinidadian Douen/Saint Lucian Dwen, it seems that this folklore may have originated from the Mayan folklore Tata Duende or the Latin-American folklore of duende.
