A trader has arrived by ship and he offers his wares to the natives in exchange for fruit and horns. He has cellarman's corkscrews and a funnel. The deal is done. One native is wearing the funnel as a hat and three natives are wearing the corkscrews on necklaces and as earrings.

So what is a magic lantern?:

In The Book of the Lantern published in 1889, author Thomas Cradock Hepworth attributes the conception of projecting images to Athanasius Kircher, a Jesuit of the 17th Century. He notes "... For in one of these books, Ars Magna Lucis et Umbre, we not only find descriptions and diagrams of numerous optical contrivances, but several which show that Kircher quite understood the main principle upon which the optical lantern depends." Others attribute the idea to a much earlier time citing the work Liber Instrumentorum by Giovanni de Fontana from the early 15th Century. And in 1589 Giovanni Baptista della Porta published Magiae Naturalis Libri Viginti which outlined his method of projecting images.

Whoever had the original idea can certainly be recognized as the one who created the forerunner to the modern slide projector. The early instruments used a glass slide which could have multiple images. The "show" was projected on a wall or screen by sliding the glass past the light source (oil lamps early on) which illuminates it through the lens.
