Ymadawiad Arthur ('The Passing of Arthur')[1] is a Welsh-language poem, some 350 lines in length,[2] by T. Gwynn Jones. It won its author the Chair at the National Eisteddfod in 1902 but was several times heavily revised by him in later years. It portrays King Arthur's last hours with his companion Bedwyr at the battle of Camlann and his final departure for Afallon. Ymadawiad Arthur is a hugely influential work, widely held to have opened a new era for Welsh-language poetry,[3] marking the beginning of the early 20th-century renaissance of Welsh literature.[4]
