Political strife and religious faction lacerated fourteenth-century Italy. Giotto's commissions are best understood against the background of this social turmoil. They reflected the demands of his patrons, the requirements of the Franciscan Order, and the restlessly inventive genius of the painter. Julian Gardner examines this important period of Giotto's path-breaking career through works originally created for Franciscan churches: Stigmatization of Saint Francis from San Francesco at Pisa, now in the Louvre, the Bardi Chapel cycle of the Life of St. Francis in Santa Croce at Florence, and the frescoes of the crossing vault above the tomb of Saint Francis in the Lower Church of San Francesco at Assisi.
