Compagnia di San Francesco Altarpiece, predella – Saint Francis Receives the Stigmata Fra Angelico (1400-1455)

The picture has something of this: god, people, veil, Renaissance, man, wear, saint, book, reclining, war, tree, skirmish, cross.
Perhaps it’s a painting of a man kneeling down next to a man with a bird on his head and another man reaching out.
