important commissions. One of these was an altarpiece for the Confraternity of the Purification in Florence, originally housed in the Convent of San Marco. The Virgin and Child Enthroned among Angels and Saints that he produced between 1461 and 1462 for this occasion now houses in the National Gallery, London. Late years in Tuscany San Gimignano In 1463, likely in fear of the plague, Gozzoli left Florence for San Gimignano, where he executed some extensive works. Most prominent of these is his seventeen-panel fresco cycle on The Life of St Augustine, covering the entire apsidal chapel in the church of Sant'Agostino. In that same church Gozzoli also completed a composition of St. Sebastian Protecting the City from the Plague, in which he depicted St. Sebastian fully clothed and unhurt, thereby going against iconographic canon. In 1465, at the town's heart in the Collegiate Church of Santa Maria Assunta, Gozzoli furthermore painted a fresco of the Martyrdom of Sebastian. He stayed in San Gimignano until 1467, completing some further works in the city and its vicinity. Pisa In 1469, Gozzoli moved to Pisa and began working on his most extensive commission: the vast series of mural paintings in the Campo Santo edifice of Pisa. There, he depicted twenty-four subjects from the Old Testament, ranging from the Invention of Wine by Noah to the Visit of the Queen of Sheba to Solomon. He was contracted to paint three subjects per year for about ten ducats each. It appears, however, that this contract was not strictly adhered to, for the actual rate of painting was only three pictures in two years. Perhaps the great multitude of figures and accessories was accepted as a set-off against the slower rate of production. By January 1470 he had executed the fresco of Noah and his Family, followed by the Curse of Ham, the Building of the Tower of Babel (which contains portraits of Cosimo de' Medici, the young Lorenzo, Angelo Poliziano and others), the Destruction of Sodom, the Victory of Abraham, the Marriages of Rebecca and of Rachel, the Life of Moses, etc. In the Cappella Ammannati, facing a gate of the Campo Santo, he also painted an Adoration of the Magi, wherein appears a portrait of himself. All this enormous mass of work, in which Benozzo was probably assisted by Zanobi Machiavelli, was performed, in addition to several other pictures during his stay in Pisa
