Geertgen tot Sint Jans – Saint John’s Altar, detail; wing, outer side, fate of the bones of Saint John the Baptist Kunsthistorisches Museum

The picture has something of this: people, many, wear, group, shopping, crowd, woman, festival, ceremony, man, market, stock, street, city, dress, celebration, priest.
Perhaps it’s a painting of a group of people standing in front of a body of water and a crowd of people.
