An old engraving of a man inside a large treadwheel working to raise water from a well in medieval times. It is from a Victorian mechanical engineering book of the 1880s. A treadwheel or treadmill is a form of engine typically powered by humans. It may resemble a water wheel in appearance, and can be worked either by a human treading paddles set onto its exterior circumference (treadmill), or by a human (or animal) doing the same inside it (treadwheel – as here). These devices were sometimes used as a punishment. The term ‘treadmill’ has come to refer to an exercise machine.
