Portrait of a knight of St. James Eberhard (Monsu Bernardo) Keilhau (1624-1687)

The picture has something of this: people, man, portrait, veil, wear, lid, pants, two, exploration, facial hair, leader, sword, scientist, woman.
Perhaps it’s a painting of a man in a black outfit holding a piece of paper in one hand and a glove in the other hand in his other hand.
