Шампень, Филипп де (1602 Брюссель - 1674 Париж) – Парижские прево и финансисты Part 6 Louvre

The picture has something of this: people, group, woman, wear, priest, leader, veil, man, portrait, many, Mary, ceremony, music, Easter, performance.
Perhaps it’s a painting of a group of men in red robes standing in front of a crucifix with one holding a book.
