St. Jerome 

This drawing of "St. Jerome" by Andrea del Castagno features the saint in the center, flanked by two other figures. Castagno, a prominent Florentine painter of the Early Renaissance, is known for his powerful and expressive style, which is evident in this drawing. The figures are depicted in a simplified manner, with a focus on their form and gesture, emphasizing their spiritual devotion. Though a sketch, the work shows Castagno's unique approach to depicting the human form.
