Sistine Chapel ceiling, Fresco cycle in Sistine Chapel, Vatican City

The Sistine Chapel ceiling is a cycle of frescoes extending across the entire vaulted surface, featuring more than 300 figures arranged within a symmetrical framework of painted architectural elements. Michelangelo divided the expanse into panels depicting biblical scenes, prophets, and sibyls, all rendered directly onto the plaster while still wet.

Pope Julius II commissioned Michelangelo between 1508 and 1512 to replace the earlier ceiling decoration of painted stars on a blue background. The artist worked largely alone and developed his technique as he progressed, gradually departing from traditional fresco methods to achieve more dynamic compositions.

The chapel takes its name from Pope Sixtus IV, who built it between 1477 and 1480; the ceiling was added under Julius II. Below Michelangelo's vault, the walls carry frescoes by Botticelli, Ghirlandaio and Perugino, and Raphael's tapestries of 1515–1516 are still hung on special occasions. The room remains the setting for papal conclaves and services.

The ceiling covers more than 500 m² of a low barrel vault, so the nine Genesis scenes read from the altar end back toward the entrance door. Michelangelo worked alone from 1508 to autumn 1512, and the first Mass was celebrated in the chapel on 1 November 1512. Look for the simulated architectural ribs that divide the painted fields.

Michelangelo painted the entire ceiling while standing on scaffolding, developing neck strain that he later documented in personal writings and poetry. The pigments were applied directly onto wet plaster, bonding chemically with the surface as it dried and creating colors that have lasted for centuries without major fading.
