Lanterns were usually made from a metal frame, commonly with a hook or hoop of metal on top. Though some lanterns had up to eight sides, five or six was not uncommon but four was the standard. These would be made of some translucent material, now usually glass or plastic but formerly thin sheets of animal horn or tinplate punched with holes or, more ornately, in decorative patterns; though some antique lanterns have only a metal grid.
