Santi Onofrio. Nicola da Tolentino and a holy bishop Domenico Panetti (1460-1530)

The picture has something of this: people, man, facial hair, god, cross, saint, portrait, mustache, book, Renaissance, crown, beard, priest, Gothic, holy.
Perhaps it’s a painting of three men with long white hair and beards, one of them is holding a book and the other one.
