During the Renaissance, a book of hours was intended for private devotional use by the laity as an expression of the desire to imitate the prayer life of nuns and monks. This manuscript was created in 1469 by Taddeo Crevelli, one of the major illuminators of manuscripts in Italy. Kurt Barstow discusses each of Crevelli's paintings and relates its iconography to other devotional images of the time. All 24 of Crevelli's images are reproduced along with sample leaves and comparative illustrations from other sources.
