Felec of Cornwall was a British saint and writer who lived in Cornwall during the 5th or 6th century. He is associated with the area of Phillack, located near Hayle, and is sometimes confused with the Roman Saint Felicity. According to tradition, he possessed the unique ability to communicate with cats. He is also linked to the mythical King Felix and was the father of Mark of Cornwall. His history is tied to the lost diocese of Dunwich and the legendary submerged land of Lyonesse.
