Verso two studies of arms, a profile looking upwards and a standing figure

This drawing shows the artist practicing different parts of the human body on a single page. One detailed sketch focuses on the muscles and tension of an arm, while another captures a head tilted back as if looking toward the heavens. These fragments were made to help the artist master realistic poses and musculature for a larger composition.

The focus on anatomical realism in Renaissance drawing was part of the broader discipline of natural philosophy, aiming to reveal the 'microcosm' of the human body. The upward-looking profile reflects the Neoplatonic concept of the soul’s aspiration toward the divine, a theme central to Raphael’s work in the Vatican Stanze.
