By the commercial theater’s closure in 1642, frequent playgoers commanded a vast trove of knowledge regarding the devices, tropes, character types, and genres of the commercial theater. But those conventions were as exploitable as they were familiar, and Chapter 5 shows how theater practitioners managed to surprise those spectators with especially long horizons of dramatic expectation. The chapter examines the striking durability of revenge tragedy in the commercial theater by juxtaposing two plays that nearly bookend its heyday: Thomas Kyd’s The Spanish Tragedy and Philip Massinger’s The Roman Actor. In revealing the ways that The Roman Actor exploits spectators’ knowledge of Kyd’s play, as well as the tropes of revenge tragedy more broadly, the chapter outlines the techniques by which Caroline theater practitioners made the eminently familiar newly strange.
