Prayer in the House of an Arnaut Chief Jean-Léon Gérôme (1824-1904)

The picture has something of this: people, group, wear, ceremony, woman, man, priest, many, room, leader, indoors, veil, music, education, furniture, wedding, prayer, school.
Perhaps it’s a painting of a group of people standing next to each other in front of a wall with a bunch of knives hanging from it’s hooks.
