Vittore Carpaccio (c. 1460-c. 1526) – Sermon of Saint Stephen Outside the Walls of Jerusalem Part 1 Louvre

The picture has something of this: people, monk, prayer, group, worship, many, spirituality, wear, religious, holy, god, ceremony, Easter, priest, ritual, temple.
Perhaps it’s a painting of a group of people standing in front of a castle with a man in a red robe.
