Florentine painting
In 1508 Pope Julius II succeeded in getting the sculptor Michelangelo 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, who had yielded to the Pope's demands with little grace, 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.
Giuliano Bugiardini
Some years later in Rome, while at work on the ceiling of the Sistine Chapel, Michelangelo sought Giuliano Bugiardini's services but later rejected them. Vasari mentioned Bugiardini assisted Michelangelo very briefly in 1508 with the painting of the ceiling of the Sistine Chapel. He painted a "Martyrdom of St Catherine" for Santa Maria Novella in Florence, based on Michelangelo's sketches. He also painted in Bologna in 1526–1530.
