Jacopo di Cione and workshop – The Trinity – Central Pinnacle Panel Part 4 National Gallery UK

The picture has something of this: god, saint, aura, church, book, people, holy, spirituality, gold, cross, crown, symbol, prayer, sculpture, sacred, worship, ancient.
Perhaps it’s a painting of a crucifix with a man holding a cross and a snake wrapped around the edge of the crucififix.
