Zahn's important work on the telescope treats the subject of optics in detail at the moment of its great flourishing. Grinding lenses with precision and compounding their power brought everything from distant galaxies to microscopic lifeforms into focus. Imagine the excitement of discovery in this period. Even as modern people, we marvel at the world we see at the other end of the lens. Zahn also describes the camera obscura, lantern slides, and projection. With the right arrangement of lenses and mirrors, he showed how to project the image seen through a telescope or microscope onto a wall, along with other inventions, including a plan for a portable camera 150 years before a practical model was built.
