This study examines the later plays of Luigi Pirandello - those he wrote for his muse, actress Marta Abba - in light of the recent publication of their correspondence. It traces the Nobel Prize winner's entire creative process, revealing how his perception of women shaped his philosophy of art and life, and highlights the structurally necessary shift from the male protagonist of the early and more famous plays and novels to the female protagonist of the later plays. With sensitive commentary on the letters, Daniela Bini reads the plays the old maestro wrote for the young actress as the sublimation of an erotic impulse he denied throughout his life. From Diana and Tuda to The Mountain Giants, Bini maintains, Pirandello makes love to Marta in the only way he could, the mystical union of the creator and his muse.
