Some of the world's foremost examples of Renaissance art grace the ceiling of the spectacular Sistine Chapel. Originally built in 1479 under the direction of Pope Sixtus IV, the chapel forms a part of the Vatican City's Apostolic Palace. It is here that the College of Cardinals gather to elect a new Pope and has been the host of such gatherings and other Papal functions since it was first conceived of. At the time of its construction, while the walls of the chapel were painted with frescoes by artists like Sandro Botticelli, Pinturicchio and Cosimo Roselli, the ceiling was rendered a simple, solid blue with stars. It was not until 1508 that Pope Julius II commissioned Michelangelo to paint the ceiling of the Sistine Chapel. Many considered this an odd choice as Michelangelo, at that time, was not known as a skilled painter. This led to speculations that Michelangelo's lofty commission was a ploy devised by rival artists Raphael and Bramante to ensure his fall from grace. Not to be deterred, Michelangelo envisioned and achieved a series of frescoes that depict scenes from the Old Testament, beginning with Creation and ending at Noah's voyage aboard his ark. Each a masterpiece in its own right, together they form a vision of unmatched artistry that draws millions of visitors to the Pope's residence each year.
