In the Aulla chapel we can see also the original incense lamp that Galileo Galilei used for calculation of pendular movements. This lamp is the one Galileo saw inside the cathedral, now replaced by a larger more elaborate one. The last chapel was "Dal Pozzo", commissioned by archbishop of Pisa Carlo Antonio Dal Pozzo in 1594; it has an altar dedicated to St. Jerome and a little dome. In this chapel in 2009 were translated the relics of the Cathedral: the relics include among the others eleven of the twelve Apostles, two fragments of the True Cross, a thorn from the Crown of Thorns of Christ and a small piece of the dress of the Virgin Mary. Also in the Dal Pozzo chapel sometimes a Mass is celebrated. The Campo Santo contained a huge collection of Roman sarcophagi, but there are only 84 left together with a collection of Roman and Etruscan sculptures and urns, now in the Museum of the vestry board. The sarcophagi were initially all around the cathedral, often attached to the building itself. That until the cemetery was built, then they were collected in the middle all over the meadow. Carlo Lasinio, in the years he was the curator of the Campo Santo, collected many other ancient relics that were spread in Pisa to make a sort of archeological museum inside the cemetery. Nowadays the sarcophagi are inside the galleries, near the walls. The walls of the vast structure were covered in over 2600 meters squared of frescoes, a greater expanse than the Sistine Chapel. The earliest, attributed to Francesco Traini, were painted 1336/41 in the south-western corner. The "Last Judgement", "Hell", "Triumph of Death," and the "Thebaid" (stories of the Desert Fathers)"," usually attributed to Buonamico di Martino da Firenze, detto il Buffalmacco , were painted in the years after the Black Death. The cycle of frescoes continues with the "Stories of the Old Testament" by Benozzo Gozzoli (15th century) that were situated in the north gallery, while in the south arcade were the "Stories of Pisan Saints", by Andrea Bonaiuti, Antonio Veneziano and Spinello Aretino (between 1377 and 1391), and the "Stories of Job", by Taddeo Gaddi (end of 14th century). In the same time, in the north gallery were the "Stories of the Genesis" by Piero di Puccio.
