In 1961 I published a Catalogue of Italian Plays, 1500–1700, in the Library of the University of Toronto (University of Toronto Press). Since then the Library has acquired several more plays, some of them of major importance in the history of Renaissance drama. Of outstanding interest are the first edition of Giordano Bruno's Il Candelaio, the first edition of the prose version of Ariosto's Gli suppositi, the first edition of Ottavio Rinuccini's L'Euridice, and the 1620 edition of Prospero Bonarelli's Il Solimano with the handsome plates etched by Jacques Callot.
