Llyr: HLIR
Welsh: Sea
Llyr Llediath: HLIR HLE-dath
Welsh: Sea Half-speech.
Welsh god of the sea, equivalent to the Irish god Lir, and to King Lear/Leir. He married Penardun--sovreignty--who gave birth to his children Bran/Bendigedfran, Branwen, and Manawyddan. Legend says that he was taken prisioner (The Three Supreme Prisoners of the Island of Britain) by Eurowyssedd (Ostorius?) the Roman, and taken then to Rome with Bran.
Elsewhere, he may be identified with Llwyr (whose name means "complete"), possessor of a magic cup in the story "Culhwch ac Olwen" in the Mabinogion. As the Fisher King's father is said to be the one fed by the Grail in Perceval, and Bran is the Fisher King, then Llyr is the Old King of the legend.
Llyr, like his counterparts, is a figure of tragedy; his family usually comes to ruin, as with the battle over Branwen and usurption of Manawyddan in the Mabinogion. |
