How did King Arthur die?
Battle of Camlann
Camlann is mentioned in Peniarth MS.37, a 14th-century copy of the Gwentian Code of the Welsh Laws, which (according to Peter Bartrum) shows that it was a topic familiar to Welsh writers. The law states "when the queen shall will a song in the chamber, let the bard sing a song respecting Camlan, and that not loud, lest the hall be disturbed." The 15th/16th-century poet Tudur Aled says that the battle came about through the treachery of Medrod and happened "about two nuts".[16] In the 13th/14th-century Welsh tale The Dream of Rhonabwy,[17] the immediate cause of the battle is a deliberate provocation by Arthur's rogue peace envoy named Iddawg (Iddawc Cordd Prydain) who intentionally insulted Medrawd.[18]
