El príncipe Baltasar Carlos, a caballo Diego Rodriguez De Silva y Velazquez (1599-1660)

The picture has something of this: cavalry, seated, mammal, veil, woman, people, action energy, sword, two, wear, recreation, motion, man, lid, water.
Perhaps it’s a painting of a young boy riding on the back of a brown horse in a mountainous landscape with mountains in the distance and clouds in the sky.
