Sistine Chapel ceiling motif. "When Perugino's altar painting was removed and ... "Last Judgement" fresco came to cover the altar wall", after at least twenty five years Michelangelo depicted Christ just below Jonah: not only for his role as precursor of Christ, Christianity and Christocentrism, but also because his powerful torsion of the body, bent backwards from the bust to the eyes and with his forefingers that now point the glorious Jesus to the characters of the ceiling, assumes a function of link between the Old and New Testament. In Vasari's description of the Prophets and Sibyls he is particularly high in his
Sistine Chapel congregations. These included the Christmas Day and Easter masses, at which the Pope himself was the celebrant. The other 27 masses could be held in a smaller, less public space, for which the "Cappella Maggiore" was used before it was rebuilt on the same site as the Sistine Chapel. The "Cappella Maggiore" derived its name, the Greater Chapel, from the fact that there was another chapel also in use by the Pope and his retinue for daily worship. At the time of Pope Sixtus IV, this was the Chapel of Pope Nicholas V, which had been decorated by Fra Angelico.
