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

The picture has something of this: portrait, people, cape, monk, saint, wear, veil, son, man, robe, book, lid, spirituality, church, cap.
Perhaps it’s a close up of a painting of a person wearing a black robe and holding a green plant in one hand and a blue sky in the background.
