Gallery of Sistine Chapel ceiling book of models for other artists ever since. Along the centre of the ceiling are nine scenes depicting the Story of Creation, the Downfall of Humanity and the Story of Noah as told in the Book of Genesis. The Prophets of Israel and the Sibyls of the pagan world foretold the coming of the Messiah. Both have been included by Michelangelo as a sign that the Messiah (Jesus Christ) was to come not just for the Jews but also for the Gentiles (non-Jewish people). The four corner pendentives show violent episodes in which the People of Israel were rescued from
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.
