St. Louis (Polyptych of St. Bartholomew) Bergognone (Ambrogio da Fossano) (1453-1523)

The picture has something of this: people, wear, gold, antique, ancient, traditional, crown, Gothic, man, cape, culture, Renaissance.
Perhaps it’s a painting of a man in a black and gold outfit with a cross and fleur - de - lis on his left arm and a sword in his right hand.
