a style of
drama popular in the time of
James I, Jacobean revenge tragedies went in for
vengeance (naturally), a great deal of
gratuitous violence,
rivers of blood etc., and exotic methods of murder such as poisoned skulls, a "shower of burning gold",
u.s.w.. almost the entire cast would usually end up dead one way or another.
Shakespeare's
Hamlet is heading in that direction.
Quentin Tarantino's movie
Reservoir Dogs conveys some of the feel a Jacobean revenge play.
obvious examples:
The White Devil by
John Webster;
The Revenger's Tragedy by
Cyril Tourneur, and
The Changeling by
Thomas Middleton.
