LAILOKEN
Scottish Folklore
This is the name of a class of Wild Men of the Woods in the legends and folklore of Scotland. LAILOKEN is described as a very hairy humanoid, with the power of human speech, that inhabited the Strathclyde Welsh-speaking region during the sixth century. He was credited with prophecy and called to the court of RHYDDRECH HAEL. In the fifteenth century legend LAILOKEN AND KETIGERN, it was suggested that LAILOKEN considered himself responsible for the deaths at the battle of Arfderydd (c. 573) and confessed this to the Saint Ketigern.
