Polyptych for S. Pietro in Perugia, predella – Saint Benedict Pietro Perugino (1445-1523)

The picture has something of this: people, sword, man, saint, portrait, cross, prayer, weapon, facial hair, god, woman, armor, spirituality, Renaissance.
Perhaps it’s a painting of a man with a long white beard holding a book and a staff in his right hand and a red book in his left hand.
