Cornish mythology is the folk tradition and mythology of the Cornish people. It consists partly of folk traditions developed in Cornwall and partly of traditions developed by Britons elsewhere before the end of the first millennium, often shared with those of the Breton and Welsh peoples. Some of this contains remnants of the mythology of pre-Christian Britain. The traditional folklore of Cornwall, often consists of tales of giants, mermaids, Bucca, piskies or the 'pobel vean' (little folk.) These tales are still popular today, with some events hosting a 'droll teller' or storyteller, to share Cornish myths and legends. The myths and stories of Cornwall have found much publishing success, particularly in children's books. The fairy tale Jack the Giant Killer takes place in Cornwall. Many early British legends associate King Arthur with Cornwall, putting his birthplace at Tintagel, the court of King Mark of Cornwall, uncle of Tristan and husband of Iseult, the most famous Cornish lovers. Cornwall shares its ancient cultural heritage with its 'Brythonic cousins' Brittany and Wales, as well as Ireland and parts of England such as neighbouring Devon. Many ancient tales of the Bards, whether the Arthurian Cycle, Tristan and Iseult or the Mabinogion take place in the ancient kingdom of Cerniw between Greater and Lesser Britains with a foot on either side of the 'British Sea' Mor Brettanek/Mor Breizh. Part of Cornish mythology is derived from tales of seafaring pirates and smugglers who thrived in and around Cornwall from the early modern period through to the 19th century. Cornish pirates exploited both their knowledge of the Cornish coast as well as its sheltered creeks and hidden anchorages. For many fishing villages, loot and contraband provided by pirates supported a strong and secretive underground economy in Cornwall. Legendary creatures that appear in Cornish folklore include buccas, knockers, Giants and Pixies.
