Fastolf appears in Shakespeare's early play Henry VI, part 1 as a cowardly knight who abandons the heroic Lord Talbot. In the first two folios the name of the character is given as 'Falstaffe' not Fastolf. When Shakespeare came to write Henry IV, part 1, set in the early years of Fastolf's career, he created a disreputable boon companion for the young Prince Hal called Sir John Oldcastle. The descendants of the real Oldcastle complained, so the name was changed to Sir John Falstaff, under which name he is identified in three later plays.
