sommewalker Posted February 12, 2015 Share Posted February 12, 2015 STANHOPES............ were invented in France ,Stanhopes or Stanho-scopes are optical devices that enable the viewing of microphotographs without using a microscope. They were invented by René Dagron in 1857. Dagron bypassed the need for an expensive microscope to view the microscopic photographs by attaching the microphotograph at the end of a modified Stanhope lens. He called the devices bijoux photo-microscopiques or microsco...pic photo-jewelry. In 1862, Dagron displayed the devices at the Exhibition in London, where he got an "Honourable Mention" and presented them to Queen Victoria. In 1864 Dagron became famous when he produced a stanhope optical viewer which enabled the viewing of a microphotograph 1 square millimetre (0.0016 sq in), (equivalent in size to the head of a pin), that included the portraits of 450 peoplethis particular one shows 4 churches adjacent to the main battlefields in France,the photos were taken using a digital microscope ,they are much clearer when viewed with the naked eye ,the main cross is hand carved from animal bone as are the plain beads and the intricately carved other beads,France being mainly a catholic country its easy why they chose a rosary ,what it does show is the technical skill of the carvers and the usage of materials to hand , as animal bones were easier to come by than say ivory,at a fraction of the cost,another way of collecting ww1 militaria , and something different from the mainstream items like bombs and bullets 3 Quote Link to comment Share on other sites More sharing options...
