Crusader warrior Raffaele Deleidi (1823-1865)

The picture has something of this: armor, sword, knight, portrait, helmet, people, weapon, soldier, man, tunic, wear, Renaissance, warrior, war, shield, Gothic, veil.
Perhaps it’s a painting of a man with a beard wearing a suit of armor and holding a sword in one hand and wearing a helmet with a feather on the other hand.
