Marco Pino, also known as Marco da Siena, studied under Domenico Beccafumi and spent his career in Siena, Rome and Naples. In Rome, Pino worked with Perino del Vaga on the Sala Paolina of Castle Saint Angelo and would also have come into contact with Salviati, Michelangelo and Taddeo Zuccaro. According to G.P. Lomazzo, Michelangelo advised Pino on the most effective method of constructing his compositions. This drawing depicts St. George, the mythical Roman tribune from Cappadocia, slaying the evil dragon. Pino’s drawings have been little studied, making it difficult to date this work, though it is a strong example of the elegance and delicacy of his draftsmanship.
