During medieval times, the diffusion of Indian and Persian irrigation technologies gave rise to an advanced irrigation system which bought about economic growth and also helped in the growth of material culture.

The earliest clear evidence of a Water wheel comes from the ancient Greece and Asia Minor, being recorded in the work of Apollonius of Perge of c. In the 1st century BC, the Greek epigrammatist Antipater of Thessalonica was the first to make a reference to the waterwheel, which Lewis has recently argued to be a vertical wheel. Antipater praised it for its use in grinding grain and the reduction of human labour.

Modest numbers of water wheels have been identified in various parts of the Greek and Roman World, and they may have once been much more extensive than historians have recognised. Most towns and cities had good aqueducts, and it would not have been difficult to harness part of the supply to driving water wheels for milling, fulling, crushing and sawing wood and stone such as marble.

The Romans used both fixed and floating water wheels and introduced water power to other parts of the Roman Empire. The basic construction is described by the engineer Vitruvius writing in 25 BC in his work De Architectura. The Romans were known to use waterwheels extensively in mining projects, with enormous Roman-era waterwheels found in places like modern-day Spain. They were reverse overshot water-wheels designed for removing water from mines. A series of overshot mills existed at Barbegal near Arles in southern France where corn was milled for the production of bread. Floating mills were also known from the later Empire, where a wheel was attached to a boat moored in a fast flowing river.

Two types of hydraulic-powered chain pumps from the Tiangong Kaiwu of , written by the Ming Dynasty encyclopedist Song Yingxing Chinese water wheel history almost certainly has a separate origin. Early waterwheels were invariably horizontal waterwheels. By at least the 1st century AD, the Chinese of the Eastern Han Dynasty began to use waterwheels to crush grain in mills and to power the piston-bellows in forging iron ore into cast iron. In the text known as the Xin Lun written by Huan Tan about 20 AD during the usurpation of Wang Mang , it states that the legendary mythological king known as Fu Xi was the one responsible for the pestle and mortar, which evolved into the tilt-hammer and then trip hammer device.

Although the author speaks of the mythological Fu Xi, a passage of his writing gives hint that the waterwheel was in widespread use by the 1st century AD in China. Researchers believe that the wheelbarrow first appeared in classical Greece, sometime between the sixth and fourth centuries B. Although wheelbarrows were expensive to purchase, they could pay for themselves in just 3 or 4 days in terms of labor savings. In fact, the wheel, which the goddess Fortuna spins to determine the fate of those she looks upon, is an ancient concept of either Greek or Roman origin, depending on which academic you talk to.

And William Shakespeare alludes to it in a few of his plays. Camels supplanted the wheel as the standard mode of transportation in the Middle East and northern Africa between the second and the sixth centuries A. Richard Bulliet cites several possible reasons in his book, The Camel and the Wheel , including the decline of roads after the fall of the Roman Empire and the invention of the camel saddle between and B. Despite abandoning the wheel for hauling purposes, Middle Eastern societies continued to use wheels for tasks such as irrigation, milling and pottery. This type of execution was medieval even by medieval standards. In another variation, Saint Catherine of Alexandria was wrapped around the rim of a spiked wheel and rolled across the ground in the early fourth century.

Catherine was named the patron saint of wheelwrights. The oldest, most common design for a perpetual motion device is the overbalanced wheel. For centuries, tinkerers, philosophers, mathematicians and crackpots have tried to design perpetual motion devices that, once set in motion, would continue forever, producing more energy than they consume. One common take on this machine is a wheel or water mill that uses changes in weight to continually rotate. The overbalanced wheel, for example, has weighted arms attached to the rim of the wheel that fold down or extend out. But no matter what the design, they all violate the first and second laws of thermodynamics, which state, respectively, that energy cannot be created or destroyed and that some energy is always lost in converting heat to work.
