Floating down to Camelot

Edward III reigned 1327 - 1377. Malory wrote in c. 1460s. Chretien de Troyes wrote chivalric Arthurian romances in the 12th century. It wasn't really that any one man "updated" Arthurian legends, more a case of them being constantly retold and changed over the centuries, to suit the society of the day. Edward III, though, was particularly interested to Arthurian legend. He had a Round Table, and instituted the Order of the Garter as a deliberate attempt to emulate romantic chivalric legends of old.
