Which famous artist painted the ceiling of the Sistine Chapel?

Between 1508 and 1512, under the patronage of Pope Julius II, Michelangelo painted the chapel's ceiling.

Michelangelo di Lodovico Buonarroti Simoni (6 March 1475 – 18 February 1564) was an Italian sculptor, painter, architect, and poet of the High Renaissance who exerted an unparalleled influence on the development of Western art. Considered to be the greatest living artist during his lifetime, he has since been described as one of the greatest artists of all time.

A number of Michelangelo's works of painting, sculpture, and architecture rank among the most famous in existence. His output in every field of interest was prodigious; given the sheer volume of surviving correspondence, sketches, and reminiscences taken into account, he is the best-documented artist of the 16th century.

Despite holding a low opinion of painting, Michelangelo also created two of the most influential frescoes in the history of Western art: the scenes from Genesis on the ceiling of the Sistine Chapel in Rome, and The Last Judgment on its altar wall. As an architect, Michelangelo pioneered the Mannerist style at the Laurentian Library. At the age of 74, he succeeded Antonio da Sangallo the Younger as the architect of St. Peter's Basilica. Michelangelo transformed the plan so that the western end was finished to his design, as was the dome, with some modification, after his death.
