Studies for the Trinity of San Severo and sketches after Leonardo

This drawing captures Raphael's meticulous study of human anatomy and expression, including a detailed portrait of a young man and a head tilted back in contemplation. In the upper left, faint outlines of a cavalry battle show the artist practicing the dynamic movement found in the works of Leonardo da Vinci. These studies served as preparation for the artist's fresco of the Trinity in the church of San Severo, Perugia.

These sketches demonstrate Raphael's assimilation of Leonardo da Vinci's 'motions of the mind' (*moti mentali*), a concept from Renaissance natural philosophy suggesting that physical gestures reveal the internal states of the soul. The integration of anatomical precision with religious iconography reflects the Neoplatonic ideal of finding divine harmony within the human form.
