Zograscope
A zograscope is an optical trinket with a lens that makes a picture placed behind the lens appear very large and far away, giving the perception of being immersed in an environment.
The lens is a convex lens.
It consists of a large magnifying lens through which the picture is viewed. Devices containing only the lens are sometimes referred to as graphoscopes.
It increases the focal length of the image.
Some zograscopes have a mirror at an angle so the image can be placed flat on a table.
Zograscopes were used in the 1700s and 1800s.[1]
The etymology of zograscope comes from "zography", which comes from the Greek zōē meaning "life", and the Greek graph, referring to a written image. The name means a recorded image that appears to look life-like. This shares the same root of the word as zoetrope.[2]
Images meant to be viewed with mirror zograscopes had text written right-to-left, so that when viewed through the mirror optics, it would read the right way.
