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.
Sistine Chapel ceiling
While much of the symbolism of the ceiling dates from the early church, the ceiling also has elements that express the specifically Renaissance thinking that sought to reconcile Christian theology with the philosophy of Renaissance Humanism. During the 15th century in Italy, and in Florence in particular, there was a strong interest in Classical literature and the philosophies of Plato, Socrates and other Classical writers. Michelangelo, as a young man, had spent time at the Humanist academy established by the Medici family in Florence. He was familiar with early Humanist-inspired sculptural works such as Donatello's bronze "David" and had himself responded by carving the enormous nude marble "David", which was placed in the piazza near the Palazzo Vecchio, the home of Florence's council. The Humanist vision of humanity was one in which people responded to other people, to social responsibility, and to God in a direct way, not through intermediaries, such as the Church. This conflicted with the Church's emphasis. While the Church emphasized humanity as essentially sinful and flawed, Humanism emphasized humanity as potentially noble and beautiful. These two views were not necessarily irreconcilable to the Church, but only through a recognition that the unique way to achieve this "elevation of spirit, mind and body" was through the Church as the agent of God. To be outside the Church was to be beyond "Salvation". In the ceiling of the Sistine Chapel, Michelangelo presented both Catholic and Humanist elements in a way that does not appear visually conflicting. The inclusion of "non-biblical" figures such as the Sibyls or "Ignudi" is consistent with the rationalising of Humanist and Christian thought of the Renaissance. This rationalisation was to become a target of the Counter Reformation.
