Mark K. Vaughn (2007) says "Runciman's three-volume "History of the Crusades" remains the primary standard of comparison." However Vaughn says that Tyerman "accurately, if perhaps with a bit of hubris, notes that Runciman's work is now outdated and seriously flawed." Tyerman himself has said "It would be folly and hubris to pretend to compete, to match, as it were, my clunking computer keyboard with his [Runciman's] pen, at once a rapier and a paintbrush; to pit one volume, however substantial, with the breadth, scope and elegance of his three."
