Follower of Cimabue – Christ between Saint Peter and Saint James Major * National Gallery of Art (Washington)

The picture has something of this: saint, people, god, book, church, spirituality, holy, aura, veil, facial hair, symbol, man, antique, ancient.
Perhaps it’s a painting of a man with white hair and a beard wearing a yellow robe and holding a crucifix in one hand and a cross in the other hand.
