Sacchi, Andrea (ändrĕˈä säkˈkē) [key], 1599–1661, Italian baroque painter, b. Rome. He studied in Rome and in Bologna under Francesco Albani. His masterpiece, an allegory of Divine Wisdom (c.1629–33; ceiling fresco, Barberini Palace, Rome) typifies his classical treatment of composition. Inspired by Raphael's ideal art, Sacchi was associated with Poussin and Algardi in the championing of classical theory, in contrast to the dynamic approach of Pietro da Cortona and Bernini. Sacchi's foremost pupil was Maratti.
