The British Deck Prism Ornament

In the days before electricity, light below vessels decks was provided by candles, oil lamps and kerosene lamps. All were dangerous aboard the wooden ships. Small deck prisms were an innovative solution. Laid flush into the deck, they drew light below without weakening the planks. Deck prisms have been found in rivers, streams and oceans of the world. Each sold separately.
