Mengs, Anton Rafael – Los archiduques Fernando y María Ana de Austria Part 6 Prado Museum

The picture has something of this: people, child, furniture, baby, wear, portrait, two, costume, woman, son, god, reclining, decoration, family, monk.
Perhaps it’s a painting of two children sitting on a chair in front of a red curtain and a gold chair with a red satin drape on the floor.
