Self-Portrait with Easel Cornelis Saftleven (1607-1681)

The picture has something of this: people, wear, man, sword, armor, woman, veil, weapon, knight, two, portrait, lid, Renaissance, helmet, seat, music.
Perhaps it’s a painting of a man sitting in front of a easel with a paintbrush in his hand and an easel in his other hand next to him.
