Resumo
Frontispiece from Athanasius Kircher's (1602-1680) 'Ars Magna Lucis Et. Umbrae', (1646). Rays of Light Are Shown Bouncing off Mirrors, Together with Heavenly Bodies and Classical Symbols. Kircher Demonstrated That by Placing a Lens between a Screen and a Mirror Which Had Been Written on, a Sharp but Inverted Image of the Text Would Appear on the Screen. By Using a Spherical Water-Filled Flask as a Condenser to Concentrate the Light, Kircher Found That Texts Painted on the Mirror's Surface Could Be Projected by Light from a Candle after Dark. These Demonstrations Eventually Resulted in the Development of the Magic Lantern as a New Form of Entertainment. Science Museum Library / Science & Society Picture Library.
