Lailoken

Lailoken was a Northern Brythonic fool or prophet of the late 6th century. The Life of Saint Kentigern mentions "a certain foolish man, who was called Laleocen" living at or near the village of Peartnach (Partick) within the Kingdom of Strathclyde. Laleocen prophesied the death of King Rhydderch Hael.
