Our garden prisms are exact reproductions of those found aboard the Charles W. Morgan, America 39;s last All-Wooden whaleship, a national historic landmark preserved at mystic seaport. In the days before electricity, light below a vessels deck was limited to candles, oil and kerosene lamps. A clever solution for the light problem was the deck prism. Laid flush into the deck, the prism point drew light down below deck without weakening the planks.
