Sistine Chapel ceiling the dynamic motion, the luminous colouration, the haunting expressions of the figures in the lunettes, the abundance of putti. Gabriele Bartz and Eberhard König have said of the "Ignudi", "There is no image that has had a more lasting effect on following generations than this. Henceforth similar figures disported themselves in innumerable decorative works, be they painted, formed in stucco or even sculpted." Within Michelangelo's own work, the chapel ceiling led to the later and more Mannerist painting of the Last Judgement in which the crowded compositions gave full rein to his inventiveness in painting contorted and foreshortened figures expressing
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.
