Jacopo di Antonio (Master of Pratovecchio) – Gabriel – Frame Roundel (left) Part 4 National Gallery UK

The picture has something of this: architecture, sculpture, ancient, ornate, church, gold, retro, people, sky, cathedral, metalwork, antique, museum, outdoors.
Perhaps it’s a close up of a clock with a painting of an angel on it’s face and a clock on the back of it’s face.
