However, several medieval authors contributed to the Arthurian legends, including:
* Geoffrey of Monmouth (c. 1100-1155): His *Historia Regum Britanniae* (History of the Kings of Britain) established many of the core elements of the Arthurian myth, including Arthur's lineage, his sword Excalibur, and his knights.
* Chretien de Troyes (c. 1135-1185): A French poet who wrote romances like *Lancelot, the Knight of the Cart* and *Perceval, the Story of the Grail*, introducing characters like Lancelot and the Holy Grail into the Arthurian world.
* Thomas Malory (c. 1405-1471): His *Le Morte D'Arthur* (The Death of Arthur), written in the 15th century, is a major source for the modern understanding of the Arthurian legend, including the final battle at Camlann and Arthur's passing.
While no single author can be credited with a specific romance solely about the death of King Arthur, these authors and others contributed to the collective narrative that ultimately shaped our understanding of this iconic figure and his tragic end.
