Vera historia de morte Arthuri (The True History of the Death of Arthur) is a short, anonymous 12th- or 13th-century Latin text relating the story of King Arthur's last journey to the Isle of Avalon – which, uniquely,[1] it locates in North Wales – and the disappearance there of his body. It may have been written at Aberconwy Abbey. It has been seen as a reaction to the brief and uncircumstantial mention of Arthur's death given in Geoffrey of Monmouth's Historia Regum Britanniae, and perhaps also to Glastonbury Abbey's claim to be Arthur's place of burial. It survives in six manuscripts, but was unknown to 19th-century scholars and little known for most of the 20th century, not being published in English translation until 1979 or in the original Latin until 1981.
