Alexander Nevsky Receives Envoys. Henryk Semiradsky (1843-1902)

The picture has something of this: saint, people, church, spirituality, man, god, religious, worship, group, temple, sculpture, priest, Mary, monastery, prayer, monk, gold.
Perhaps it’s a painting of a group of people standing in front of a throne with two men and a woman sitting on one of the men’s legs.
