Some authors had been considered his work about the Fall of Constantinople as an account of an eyewitness, but it was later discovered that it was actually Christophe Richer who composed his testimony of this event based on the work of several historians, such as Egnatius Cipelli, Flavio Biondo, Bartolomeo Platina, Michele Ricci, Robert Gaugin, Paolo Giovio and Andrea Cambini.
