The art of Leonardo's younger contemporary Michelangelo took a very different direction. Michelangelo in neither his painting nor his sculpture demonstrates any interest in the observation of any natural object except the human body. He perfected his technique in depicting it, while in his early twenties, by the creation of the enormous marble statue of "David" and the group "Pietà", in the St Peter's Basilica, Rome. He then set about an exploration of the expressive possibilities of the human anatomy. His commission by Pope Julius II to paint the Sistine Chapel ceiling resulted in the supreme masterpiece of figurative composition, which was to have profound effect on every subsequent generation of European artists. His later work, "The Last Judgement", painted on the altar wall of the Sistine Chapel between 1534 and 1541, shows a Mannerist (also called Late Renaissance) style with generally elongated bodies which took over from the High Renaissance style between 1520 and 1530.
