Portrait of Stefano IV Colonna Agnolo Bronzino (1503-1572)

The picture has something of this: armor, knight, sword, helmet, people, man, warrior, weapon, portrait, shield, Gothic, Renaissance, soldier, skirmish, war, hero, ancient.
Perhaps it’s a close up of a painting of a man with a beard wearing a suit of armor and holding a helmet in one hand and a glove in the other hand.
