Ur-Hamlet

The Ur-Hamlet (the German prefix means "original") is a play by an unknown author, thought to be either Thomas Kyd or William Shakespeare, dated by scholars to the late 1580s. No copy of the play survives today. The play was staged in London, more specifically at The Theatre in as recalled by Elizabethan author Thomas Lodge. It includes a character named Hamlet; the only other known character from the play is a ghost who, according to Thomas Lodge in his 1596 publication Wits Misery and the Worlds Madnesse, cries "Hamlet, revenge!"
