The Spanish Tragedy, or Hieronimo is Mad Again[1] is an Elizabethan tragedy written by Thomas Kyd between 1582 and 1592. Highly popular and influential in its time, The Spanish Tragedy established a new genre in English theatre, the revenge play or revenge tragedy. The play contains several violent murders and includes as one of its characters a personification of Revenge. The Spanish Tragedy is often considered to be the first mature Elizabethan drama, a claim disputed with Christopher Marlowe's Tamburlaine,[2] and was parodied by many Elizabethan and Jacobean playwrights, including Marlowe, William Shakespeare and Ben Jonson.
Many elements of The Spanish Tragedy, such as the play-within-a-play used to trap a murderer and a ghost intent on vengeance, appear in Shakespeare's Hamlet. (Thomas Kyd is frequently proposed as the author of the hypothetical Ur-Hamlet that may have been one of Shakespeare's primary sources for Hamlet.)
