Pisanello (Italian, 1395-1455)3 Antonio (Antonio Pisano) Pisanello (1395-1455)

The picture has something of this: people, Renaissance, baroque, saint, nude, group, mammal, cavalry, god, allegory, baby, mythology, museum, woman, sheep.
Perhaps it’s a painting of a woman riding on the back of a horse surrounded by deer and other animals in a wooded area with a banner in the foreground.
