Emanuel Swedenborg’s Glider Sketch
The earliest examples of flying machines are from one of two sources. The first are fictional sources, such as myths or epics, and the second are exploratory sketches from great thinkers of their time, such as Leonardo da Vinci. The sketch above is an example of the latter, and it was sketched in 1714 by Emanuel Swedenborg, a Swedish polymath known for his theological works. The design is a combination of a glider and an ornithopter, and he sketched it in one of his notebooks with full knowledge that it could never fly.
