Studies for the Libyan Sibyl

Red chalk anatomical study sheet featuring muscular back, limbs, and profile head studies

Michelangelo Buonarroti

This red chalk drawing reveals Michelangelo's meticulous study of human anatomy for one of the sibyls adorning the Sistine Chapel ceiling. The artist captures muscular definition and movement through careful observation of a male model, later adapted for the female prophet. Multiple views—including a powerful back study and profile head—demonstrate his method of working through poses and details. The chalk's warm tone enhances the figure's sculptural quality. This preparatory work exemplifies the Renaissance master's dedication to anatomical accuracy as the foundation of monumental painting.
