Verso A standing saint (Peter), and a study of his right leg, Pp,1.65

This preparatory drawing shows a muscular male figure in a standing pose, looking down at a pair of large keys held in his hands. The artist uses dense cross-hatching to model the volume of the torso and limbs, reflecting the High Renaissance practice of rigorous anatomical study before applying drapery. A secondary sketch on the right side of the sheet provides a detailed examination of the musculature and weight distribution of the figure's leg.
