Glass (pre-1845)

Originally installed in the upper deck of HMS Erebus, this rectangular glass prism had one important purpose: to distribute much-needed daylight to the ship’s lower deck. It was set flush to the decking with the flat side up, making it easy for sailors to walk over it and ensuring that as much light as possible was captured and directed below deck.
