Pwca

The púca (Irish for spirit/ghost), pooka, phouka, phooka, phooca, puca or púka is primarily a creature of . Considered to be bringers both of good and bad fortune, they could either help or hinder rural and marine communities.The Púca can have dark or staunch white fur or hair. The creatures were said to be shape changers which could take the appearance of horses, goats, cats, dogs, and hares. They may also take a human form, which includes various animal features, such as ears or a tail.

The púca has counterparts throughout the Celtic cultures of Northwest Europe. For instance, in Welsh mythology it is named the pwca and in Cornish the Bucca. In the Channel Islands, the pouque were said to be fairies who lived near ancient stones; in Channel Island French a cromlech is referred to as a pouquelée or pouquelay(e); poulpiquet and polpegan are corresponding terms in Brittany.

The origin of the name may have come from the Old Norse term pook or puki, which refers to a "nature spirit". Usage of the term in Ireland, however, may predate the arrival of Norse settlers. In Germanic languages, such as Frisian or English, this became pucel, pook or puck.

The púca may be regarded as being either menacing or beneficent. Fairy mythologist Thomas Keightley said "notions respecting it are very vague", and in a brief description gives an account collected by Croker from a boy living near Killarney that "old people used to say that the Pookas were very numerous...long ago..., were wicked-minded, black-looking, bad things...that would come in the form of wild colts, with chains hanging about them", and that did much to harm unwary travellers. Also, children were warned not to eat overripe blackberries, because this was a sign that the pooka has befouled them.
