Gaulli executed his first major commission, of four large frescoes for the Pamphili family, between 1666 and 1672 in the church of Sant’Agnese in the Piazza Navona, Rome. When the original artist chosen for the project died, Gaulli was one of several invited to take over the work, and this appears to be one of his early studies for the project. It depicts saints and angels seated among the clouds, an illusionistic scene intended to connect the heavenly realm with the world of the faithful.
