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.

In 1512 Alfonso I d'Este, Duke of Ferrara went to Rome to reconcile with Pope Julius II, who had excommunicated him in summer 1510 for his alliance with Louis XII of France against the Republic of Venice. Julius absolved him and Alfonso spent a few days in Rome before returning to Ferrara. On 11 July he visited the Sistine Chapel, where Michelangelo was completing the ceiling. As he climbed the scaffolding he had a long and admiring conversation with Michelangelo, who promised him a painting.
