Pietro da Cortona was active in Rome as an architect, painter, and decorator. This majestic sheet reflects his virtuosity in all these fields, approximating High Baroque ceiling frescoes in its play of light and active, sculptural forms. It probably served as a model for a painting once in the Vatican but now lost.
