Yukio Mishima's 1965 play Madame de Sade is a three-act historical drama exploring the psyche of Renée, the devoted wife of the infamous Marquis de Sade, as she navigates his prolonged imprisonment and, paradoxically, rejects him upon his release. The play features an all-female cast, examining themes of devotion, sacrifice, power, and the "monster" behind his own philosophy.
