Pierre Le Gros was a French sculptor, active almost exclusively in Baroque Rome where he was the pre-eminent sculptor for nearly two decades.

The Church of the Gesù is the mother church of the Society of Jesus (Jesuits), a Catholic religious order. Officially named Chiesa del Santissimo Nome di Gesù, its façade is "the first truly baroque façade", introducing the baroque style into architecture. The church served as a model for innumerable Jesuit churches all over the world, especially in the central Europe and then in the Portuguese colonies. Its paintings in the nave, crossing, and side chapels became models for Jesuit churches throughout Italy and Europe, as well as those of other orders. The Church of the Gesù is located in the Piazza del Gesù in Rome.
