The Irish word "Phouka" is sometimes used, as "Pouk", or "Puck", was in Middle English, for the Devil.More usually he is a kind of bogy or bogey-beast, something like the Picktree brag of the North of England, who takes various forms, most usually a horse, but also an eagle or a bat, and is responsible for people falling as well.. Many a wild ride has been suffered on the Phouka's back.
