A Saint Monk Moretto da Brescia (Alessandro Bonvicino) (c.1498-1554)

The picture has something of this: people, man, portrait, music, wear, musician, monk, leader, sword, priest, veil, singer, side view, weapon.
Perhaps it’s a close up of a painting of a man wearing a crown and holding a crucifix in one hand and a book in the other hand.
