the Crucifixion with the Virgin and SS John the Evangelist, Laurence and Herculanus on the altar wall; and four scenes from the life of St Louis of Toulouse. The commission was altered later, and the fresco of the Crucifixion on the altar wall was not painted. The other four scenes of St Louis of Toulouse were arranged counter-clockwise from the right of the altar wall. One scene shows St Louis professing the Franciscan Rule before Pope Boniface VIII; another shows St Louis posthumously reuniting a merchant, with the church of San Domenico in Perugia clearly visible in the background; the third, badly damaged, depicts a miracle performed by St Louis; and the fourth shows St Louis's burial in a church resembling the church of St Pietro in Perugia. This half of the Priori chapel was finished in 1461, and the artist Filippo Lippi adjudicated the work and priced it at 400 Florentine florins. The works are now held in the Galleria Nazionale dell'Umbria. Totila's siege of Perugia The second half of the chapel was also commissioned to Bonfigli to decorate. The frescoes on the second half depict the scenes from the life of St Herculanus. The original commission was for four frescoes, but Bonfigli only painted three. The right of the back wall was painted with the fresco Totila's siege of Perugia. This wildly active fresco is divided into two scenes, with the siege of Totila depicted on the left and the scene after the city has fallen on the right. The left side shows Totila's army camped out around the ruins of the amphitheater outside Porta Marzia that effected the siege when it began in 542. The left scene takes place in 549, where the soldiers gather around an ox. This ox was thrown over the city walls by St. Herculanus to convince the army the city still had provisions, but the trick was ruined by a cleric who revealed the lie. The right side of the fresco shows a few citizens of Perugia laying a beheaded St Herculanus and a young boy into a grave after the city had fallen. The city in the background provides a depiction of the Colle Landone, a hill in Perugia occupied by the Etruscans in the 4th century B.C., before the building of the Roman wall Rocca Paolina in 1540. The fresco shows historical buildings of Perugia, including the Porta Marzia, the
