In the folklore of Brittany, fairies are rarely benevolent and when they are, it is usually under the tightest of conditions; the smallest infraction being punished severely. Aligned to their status as a cursed race, they are immensely powerful but fiercely proud and will not stand to be mocked or ignored. They sometimes appear seductive and protective but when provoked they can be malicious and cruel; to annoy a fairy was to expose oneself to their evil spells. There are many Breton tales of mortals battling against a fairy’s curse; one such is that of Yannick, a humble clog-maker.
First set down from the oral tradition in the middle of the 19th century, the tale of Peronnik the Idiot has often been described as a Breton re-telling of Chrétien de Troyes’ 12th century romance Perceval, the Story of the Grail. However, others maintain that the story is truly a surviving descendant of one once transmitted orally by the Celtic bards of old and that the tales of Peronnik, Perceval and the medieval Welsh romance Peredur all share the same ancient, lost source.
