Concert given by Cardinal de La Rochefoucauld at the Argentina Theatre in Rome, 1747 Giovanni Paolo Panini (1691-1765)

The picture has something of this: temple, sculpture, church, architecture, monastery, ancient, castle, people, ceiling, decoration, god, group, turning point, spirituality.
Perhaps it’s a painting of a large auditorium with a stage full of people and a man standing in the center of the room with his hands in his pockets.
