particularly appreciated by the wealthy classes passionate about science, who had a cabinet of curiosities where they can be projected in the dark. They were in fact expensive objects: in London, around 1760, they cost between 18 shillings and 2 pounds, considering that 1 shilling was the price of a day's work for a London worker!
They were also a way to familiarize oneself with the laws of optics and to introduce young people to geography. The image could be viewed with various tools. The most common is the zograscope, consisting of a wooden foot that supports a biconvex lens and a mirror inclined at 45 °. Positioned just below, the print is reflected in the mirror and the viewer observes it through the lens. The mirror creates a distance - hence the effect of depth of field - and the lens a distortion, which emphasizes the perspective. The illustrations could also be viewed in special optical boxes, equipped with an inclined mirror, but the image was hidden inside the device, making the experience more "magical". Hence the epithet of "ancestors" of modern cinema.
