Portrait of Thomas Howard, 2nd Earl of Arundel – 1629-1630 Peter Paul Rubens (1577-1640)

The picture has something of this: armor, weapon, sword, helmet, knight, people, skirmish, war, soldier, man, warrior, military, shield, veil, Renaissance.
Perhaps it’s a close up of a painting of a man wearing a suit of armor with a sword in his hand and a helmet on his head and a cane.
