Magnifier Glass


Within the concretion SCW791 a Nuremberg style magnifier glass was recovered [SCW888]. This consisted of a single strip of copper wire looped around the lens and tied with a wire thread, this was typical of the later 17th century Nuremburg design but due its simplicity it would hardly be surprising if local optical manufacturers may have independently come up with similar techniques, similar designs can be seen in contemporary spectacles (Science Museum, London, 2017). These would have been mass produced with dozens of pairs turned out daily..
