Juan Bautista Martínez del Mazo (possibly studio of) – Portrait of the Infante Balthasar Carlos (1629-1646) Mauritshuis

The picture has something of this: people, sword, armor, wear, veil, weapon, woman, Renaissance, royalty, man, sash, knight, monarch.
Perhaps it’s a painting of a young man dressed in armor and holding a sword in a room with red drapes and a red drape on the wall.
