The ancient Greeks and Romans pictured many of their gods with winged feet, and imagined mythological winged animals. According to the legend of Daedalus and Icarus, the father and son escaped prison by attaching wings made of wax and feathers to their bodies. Unfortunately, Icarus flew too near the sun, and the heat caused the wax and feathers to melt. The feathers fell off, and Icarus plummeted to the sea. Daedalus landed safely in Sicily. Hero’s Engine About 100 BC, a Greek inventor known as Hero of Alexandria came up with a new invention that depended on the mechanical interaction of heat and water. He invented a rocket-like device called an aeolipile. It used steam for propulsion. Hero mounted a sphere on top of a water kettle. A fire below the kettle turned the water into steam, and the gas traveled through the pipes to the sphere. Two L-shaped tubes on opposite sides of the sphere allowed the gas to escape, giving a thrust to the sphere, causing it to rotate.
