The Alfred Jewel and Bertrand Russell

Given the camera and the lighting, it was impossible to get a good photograph but the details are here https://en.wikipedia.org/wiki/Alfred_Jewel The piece underneath it in the museum says that "it is thought to be a representation of the sense of sight". Is that possible? It reminded me of what Bertrand Russell says about light in The Problems of Philosophy. He says that when physicists tell us that light is a wave motion, that tells you little about what you experience. He says that if you put a person blind from birth onto a ship, you could get them to experience a wave motion, but that would not let them experience light. So a representation of the sense of sight is an amazing idea. https://www.sparknotes.com/philosophy/problems/section3/
