Geoffroi de Charny

Geoffroi de Charny was the third son of Jean de Charny, the lord of Charny, and Marguerite de Joinville, daughter of Jean de Joinville, the biographer and close friend of France's King Louis IX. A renowned knight who fought on the French side during the early years of the Hundred Years' War, Charny wrote a semi-autobiographical poem, The Book of Geoffroi de Charny, and a set of questions on chivalric matters for the short-lived Company of the Star, France's counterpart to England's Order of the Garter. Although a prose treatise called the Book of Chivalry has also long been accredited to him, recent findings indicate this to have been more likely by his son of the same name, Geoffroi II de Charny, who died in 1398. Charny is also widely associated with the first known showings of the Shroud of Turin, though there are now doubts that he was responsible for these.
