Welsh mythology

The mythology Welsh includes both folk traditions developed in Wales and traditions developed by Celtic Britons elsewhere before the end of the first millennium. As in most predominantly oral societies, Celtic mythology and history were recorded orally by specialists such as the Druids.

This oral record has been lost or altered through outside contact and invasion over the years. Much of this altered mythology and history is preserved in medieval Welsh manuscripts, which include the book Hergest's Red, Rhydderch's White Book, Aneirin's Book and Taliesin's Book.

Other works related to Welsh mythology include the 9th century Latin historical compilation Historia Brittonum ("History of the British") and the 12th century Latin chronicle of Geoffrey of Monmouth Historia Regum Britanniae ("History of the Kings of Great Britain" ), as well as later folklore, such as the materials collected in The Welsh Fairy Book by William Jenkyn Thomas (1908).
