Capcaun (Romanian)
A Capcaun is a creature in Romanian folklore, depicted as an ogre who kidnaps children or young ladies (mostly princesses). It represents evil, as do its counterparts Zmeu and the Balaur. In most Romanian publications of other European works the names of creatures such as Ogres or Trolls are usually translated as capcaun.
The Romanian word appears to have meant "Dog-head" (cap being a form of cap, meaning "head", and caun a derivative of caine, "dog"). According to Romanian folkloric phantasy, the c?pc?un has a dog head, sometimes with four eyes, with eyes in the nape, or with four legs, but whose main characteristic is anthropophagy.
