This is a very nice 4-spout grease lamp, Circa 1680-1780. 4 wick lamps are one of the oldest style hanging lighting fixtures. These lamps are a squared version of the crusie lamp in which the pan was filled with grease, fat scraps, fish oil or vegetable oil. Whale oil was used after 1760. Then a simple wick or rag was placed in the spouts feeding from the oil. This lamp has a chain attached for hanging. Features a very unique tooth like design on two sides. Made from blacksmith made rolled wrought iron. Great piece that would look great in any period home or as a decorator piece. 3-1/2" H without hook.
