Re: Thursday trivia extra
I can guess what it is used for, but I'm drawing a blank on the 10-letter name. Is it also known by a two word name (6+6)?
On reflection
(not to mention some refraction) this can't be a "camera lucida" or "graph-o-scope" as I originally thought. The front element is a lens.
I'm guessing that it is a viewer for small prints or photographs.
sorta, but not quite close enough;-)
Aha!
It's a "zograscope" - for viewing "vue d'optiques" (hand colored engravings). The lens/mirror assembly gave the pictures an illusion of depth.
Thanks for the question.
