The Ghost of Clytemnestra Awakening the Furies John Downman (1750-1824)

The picture has something of this: people, baby, woman, group, Renaissance, man, kneeling, reclining, saint, room, furniture, Mary, god, veil, interaction.
Perhaps it’s a painting of a man standing in front of a group of people with one hand up in the air and the other hand out.
