Pot, Hendrik Gerritsz. – Portret van een man, gekleed als herder, 1630-1645 Rijksmuseum: part 3

The picture has something of this: weapon, man, soldier, armor, portrait, people, warrior, military, wear, war, sword, army, retro, gun, skirmish, helmet.
Perhaps it’s a painting of a man in a green dress with a staff in his hand and a crown on his head and a cane in his other hand.
