Masaccio's "Trinity" examines one of the most influential paintings of the Italian Renaissance. Renowned for the grandeur of its characterizations and for the perspectival illusion of its architectural setting, the fresco was famous from the time it was painted in the 1420s, and remembered despite its having been hidden from view for nearly two centuries. This volume considers the "Trinity" in its historical and spiritual contexts, and describes the significance of Masaccio's innovative depictions of time and space.
