The story of Shakespeare's Hamlet was derived from the legend of Amleth, preserved by 13th-century chronicler Saxo Grammaticus in his Gesta Danorum, as subsequently retold by 16th-century scholar Fran ois de Belleforest. Shakespeare may also have drawn on an earlier (hypothetical) Elizabethan play known today as the Ur-Hamlet, though some scholars believe he himself wrote the Ur-Hamlet, later revising it to create the version of Hamlet we now have. He almost certainly wrote his version of the title role for his fellow actor, Richard Burbage, the leading tragedian of Shakespeare's time.
