Lleu Llaw Gyffes (Welsh pronunciation: [ˈɬɛɨ ˈɬau ˈɡəfɛs], sometimes spelled Llew Llaw Gyffes) is a hero of Welsh mythology. He appears most prominently in the Fourth Branch of the Mabinogi, the tale of Math fab Mathonwy, which tells the tale of his birth, his marriage, his death, his resurrection and his accession to the throne of Gwynedd. He is a warrior and magician, invariably associated with his uncle Gwydion.
He is widely understood to be the Welsh equivalent of the Irish Lugh and the Gaulish Lugus. It has been suggested that Lleu, like Pryderi, is related to the divine son figure of Mabon ap Modron.[1]
