The author is then patently not a telescope maker! The article states:


              Made from rock-crystal, the lenses have an
              accurate shape that betrays the work of a
              master craftsman. The best example of the
              lenses measures 50 mm (2 inches) in diameter
              and 30 mm (1 inch) thick at its centre. 

              "The surface of some of the lenses have an
              almost perfect elliptical shape," Dr Schmidt
              said. "They were obviously made on a turning
              lathe." 

Do I need to say more?
