In 1468, Antonio di Iacopo dalle Mura, head of the Opera (1460-88), commissions a large Old Testament cycle from the Florentine artist Benozzo Gozzoli. Beginning beneath the Genesis scenes painted by Piero di Puccio in 1489-91 and extending over the entire wall of the northern gallery, the cycle is by far the largest decoration project in the Camposanto. The subjects of the twenty-three pictures progress from the story of Noah to the meeting between Salomon and the Queen of Sheba.
