The "revenge" play became the most durable and commercially successful type of drama on the Elizabethan stage. This example by Thomas Kyd, who was one of the originators of the genre, brings to life the intrigues of the Spanish court, dramatically juxtaposing romantic passion with sudden violent death and clandestine politics. The ghost of Dan Andrea and his guide Revenge observe the dark and bloody action throughout, provoking questions about the nature of the human condition.
