San Domenico Altarpiece – Saint Romulus Fra Angelico (1400-1455)

The picture has something of this: saint, aura, church, spirituality, veil, god, symbol, people, crown, pope, book, coat of arms, cross, holy, prayer.
Perhaps it’s a close up of a painting of a man wearing a priest’s robe and holding a book in one hand and a cross in the other hand.
