Dates undetermined, between 150 BC and 300 AD

The mathematician and inventor Hero is believed to have lived in Alexandria. His writings in Greek, thought to be compilations from works of ancient philosophers and mechanicians, concern studies of mechanics and pneumatics. They include nearly 80 ingenious inventions (such as siphons, fountains, and engines) which, “by the union of [compressed] air, earth, fire, and water, and the concurrence of … elementary principles … supply the most pressing wants of human life, [or] produce amazement and alarm.” His book on pneumatics describes many gadgets and magical tricks and includes the first suggestion of a steam engine, which his book on mechanics demonstrates knowledge of multiple pulleys, cogwheels, levers, and the like.
