According to contemporary accounts, Michelangelo attended the excavation of the Greek sculpture <em>Laocoön and His Sons</em> when it was unearthed near Rome in 1506. Laocoön was a Trojan priest who, along with his two sons, was attacked by sea serpents sent by the goddess Athena. The emotional agony of the sculpture fascinated Michelangelo and artists throughout Italy, inspiring copies and variations. In this drawing, a northern Italian artist referenced just one figure from the story using the chiaroscuro technique—achieved here with dark and light inks on blue toned paper—to emphasize the sculptural quality of the body.
