Two Tudor Tragedies: Gorboduc/the Spanish Tragedy (Penguin Classics)

This one-volume edition of the two most influential pre-Shakespearean tragedies in English. "Gorboduc" (1561) has claims to be the earliest English tragedy and was written jointly by Thomas Norton and Thomas Sackville. "The Spanish Tragedy" is of extraordinary interest, not only in its own right, but as as the central precusor to "Hamlet".
