Page 228, Book III from 'Forces of Nature' (Amédée Guillemin, ed. by Norman Lockyer, Macmillan & Co., London, 1877) the section on Physical Phenomenon explains and shows the 'Pinhole Image'.

POV
Without persistence of vision, we see no motion. And what we see stays on our retina for 1/14th of a second before lost.
This is why a minimum of 14 fps is required for fluid motion to be seen. Less than this and a ‘flicker’ is likely seen.

SIMON RITTER VON STAMPFER (1792-1864)
Stampfer built his ‘Stroboscope’ this year with almost exact dimensions to that of Plateau's ‘Phenakistoscope’.
So similar in construction, looks and achievement, they have oft times been mistaken as the other. https://t.co/XjC71ipC0h

The old Dutch title of a ‘Raree Show’ was ‘t Fraay Curieus’, and referred to the cries “beautiful!!!” (fraai) and “extraordinary!!!” (curieus) with which itinerant performers announced themselves when they arrived in towns & villages. https://t.co/AnINT11tH2
The ‘Raree Show’ was for the street or living room. Most were public exhibitions and hugely popular w/ children. Beginning c. 1860 it was called "in imitation of the foreign way of pronouncing rare show" [sic].
The innocent term ‘peep show’ later took on a more depraved meaning. https://t.co/KkHDtm1sli
Here is a ‘Raree Show’ with two lassies ‘peeping’ into the box, from Olive Cooks 'Movement in Two Dimensions- A Study of the Animated and Projected Pictures Which Preceded the Invention of Cinematography', Hutchinson & Co., 1963, p29. https://t.co/LVo4M1ADic
The ‘Raree Show’ was an exhibition of pictures, objects (or a combination of both), viewed through a small hole or magnifying glass into a ‘Peep Box’ operated by a travelling itinerant showman.
It was a popular form of entertainment during the 17th and 18th centuries in Europe. https://t.co/UXmIxRZhAj
