Antique Maritime Deck Prism

This antique deck prism comes complete with both sides of the frame, which are solid brass.

Deck prisms serve as a safe source of natural sunlight to illuminate below decks. This invention precedes electricity; it allowed illumination of spaces without using candles or lamps, which created a fire risk on the wooden shifts. The prism would lay flush with the deck, with its prism shape acting to disperse light efficiently under the deck.

Considering its age, this is prism is in fantastic shape. The prism itself measures 9.75 x 2.5 x 3. The brass frames measure 11.25 x .25 x 4.5.

A really cool piece of maritime / nautical history!
