Description
Late 19th -Century Polemoscope or Jealousy Glass. Invented by the German-Polish astrromer Johannes Hevelius in 1637, the polemoscope is a monocular with an oblique mirror that allows the viewer to see objects and persons not directly in front of their eyes. The term “jealousy glass”comes from the image of an infatuated person keeping an eye on the object of their affection at the theater or opera without that person being aware that that they are being watched. This unsigned example in brass is likely English in origin and late 19th-century in date. It is 7cm high and the diameter of the base is 5cm.
