Italian Renaissance painting
In 1508 Pope Julius II succeeded in getting the Florentine sculptor Michelangelo (1475-1564) to agree to continue the decorative scheme of the Sistine Chapel. The Sistine Chapel ceiling was constructed in such a way that there were twelve sloping pendentives supporting the vault that formed ideal surfaces on which to paint the Twelve Apostles. Michelangelo soon devised an entirely different scheme, far more complex both in design and in iconography. The scale of the work, which he executed single handed except for manual assistance, was titanic and took nearly five years to complete.
Santa Maria Maggiore
The Mannerist interior decoration of the Sistine Chapel was completed (1587–1589) by a large team of artists, directed by Cesare Nebbia and Giovanni Guerra. While the art biographer, Giovanni Baglione allocates specific works to individual artists, recent scholarship finds that the hand of Nebbia drew preliminary sketches for many, if not all, of the frescoes. Baglione also concedes the roles of Nebbia and Guerra could be summarized as "Nebbia drew, and Guerra supervised the teams".
