Light Raypaths through Lenses and Prisms C017 / 3485
Plate from 18th century encyclopedia showing light raypaths through lenses and prisms, a magic lantern and a camera. Also shown is a method for calculating the height of buildings by using the shadows it casts by the sun. Also shown are 2 illustrations of catoptric cistulas, a box with several sides lined with mirrors, so as to magnify or multiply images of any object placed inside the box. Of these, there are various kinds for various purposes, such as magnification, deformation, or multiplication of images

EDITORS COMMENTS
This print from the 18th-century encyclopedia takes us on a journey through the fascinating world of optics and visual perception. The intricate illustration showcases an array of lenses, prisms, and devices like the magic lantern and camera obscura, which were instrumental in shaping our understanding of light. Intriguingly, this image also reveals a method for calculating building height using shadows cast by the sun. It highlights how early scientists ingeniously utilized natural phenomena to solve practical problems. The two illustrations of catoptric cistulas steal the spotlight with their unique ability to magnify or multiply images placed inside these mirrored boxes. These versatile contraptions served various purposes such as magnification, deformation, or multiplication of images – a testament to human curiosity and ingenuity. As we delve into this visual feast encompassing concepts like convexity, focus, concavity, prisms, lenses - it becomes evident that this plate encapsulates centuries' worth of optical knowledge passed down through generations. It reminds us of humanity's relentless pursuit to unravel the mysteries surrounding light and vision. David Parker's remarkable capture from Science Photo Library transports us back in time while simultaneously celebrating our collective scientific heritage. This print serves as a reminder that even today we continue to build upon these foundations laid centuries ago by pioneers who paved the way for modern advancements in optics and imaging technology.
