- Leonardo da Vinci's Glider and Parachute Idea
Leonardo da Vinci, the great Italian artist and scientist, who lived in the fifteenth century, spent years experimenting with the idea of flying. He made a number of sketches of wings to be fitted to the arms and legs of man. His plan for a parachute was soundly worked out and his idea that the wings of a flying machine should be patterned after the wings of the bat found expression in the doped fabric covering of our early airplanes. - Principle of the parachute, drawing by Leonardo da Vinci
If Leonardo da Vinci's aerial flight experiments do not seem to have been carried out on a large scale, it is perhaps not the same with the parachute, the use of which is much safer. The description of Leonardo da Vinci was reproduced later, not without a notable improvement in the mode of representation of the apparatus, in a collection of machines, due to Fauste Veranzio and published in Venice in 1617. - Principle of the helicopter, drawing by Leonardo da Vinci

The examination of the original drawings of the great Italian artist is intersting. We reproduce by heliogravure a complete plate; it makes it possible to follow the thought which presided over its execution. We let Dr. Hureau de Villeneuve interpret it. We see in the second row on the right a small character quite similar to a demon or a genie, for he wears a flame on his head and, next to this flame, a Latin cross. His arms end with the fingers of a bat. The figure is not yet finished when Leonardo already recognizes its insufficiency and, guessing the little muscular action of the arms, thinks of using the force of the legs. So we see a little higher, in the same plank, a vigorous man placed on his stomach, his legs bent and about to launch a violent kick. The protruding muscles, traced by an anatomist's pencil, reveal the great painter in an unassuming drawing.
