British Celtic Mythology encompasses the rich tapestry of myths and legends from the Celtic peoples of Britain, including the Celts of Wales, Scotland, Ireland, and Cornwall. This mythology features a pantheon of deities, such as Brigid and Cernunnos, and is characterized by themes of nature, the supernatural, and the interconnectedness of life. The stories often involve heroic figures, like King Arthur and the Knights of the Round Table, as well as mythical creatures such as fairies and dragons. These tales were traditionally passed down orally and later recorded in texts like the Mabinogion and Lebor Gabála Érenn, preserving the cultural heritage of the Celts.
