Two Grotesque Heads 

"Two Grotesque Heads" is a study of two exaggerated, caricatured faces by Francesco Melzi, a pupil and close associate of Leonardo da Vinci. This drawing, likely created in the early 16th century, showcases Melzi's talent for capturing the human form through both meticulous detail and playful exaggeration. The two figures are shown in profile, their features distorted and emphasized for humorous effect, reflecting an interest in grotesquerie that was common in Renaissance art. The drawing demonstrates Melzi's ability to capture both the subtle nuances and the dramatic aspects of human expression, which may have been influenced by his master's own anatomical studies.
