This list of ancient watermills presents an overview of water-powered grain-mills and industrial mills in classical antiquity from their Hellenistic beginnings through the Roman imperial period.
The watermill is the earliest instance of a machine harnessing natural forces to replace human muscular labour (apart from the sail).[3] As such, it holds a special place in the history of technology and also in economic studies where it is associated with growth.[4]
The initial invention of the watermill appears to have occurred in the hellenized eastern Mediterranean in the wake of the conquests of Alexander the Great and the rise of Hellenistic science and technology.[5] In the subsequent Roman era, the use of water-power was diversified and different types of watermills were introduced. These include all three variants of the vertical water wheel as well as the horizontal water wheel.[6] Apart from its main use in grinding flour, water-power was also applied to pounding grain,[7] crushing ore,[8] sawing stones[9] and possibly fulling and bellows for iron furnaces.[10]
An increased research interest has greatly improved our knowledge of Roman watermill sites in recent years. Numerous archaeological finds in the western half of the empire now complement the surviving documentary material from the eastern provinces; they demonstrate that the breakthrough of watermill technology occurred as early as the 1st century AD and was not delayed until the onset of the Middle Ages as previously thought.[11] The data shows a wide spread of grain-mills over most parts of the empire, with industrial mills also being in evidence in both halves.[12] Although the prevalence of grain-mills naturally meant that watermilling remained a typically rural phenomenon, it also rose in importance in the urban environment.[13]
The data below spans the period until ca. 500 AD. The vast majority dates to Roman times.
Below the earliest ancient evidence for different types of watermills and the use of water-power for various industrial processes. This list is continued for the early Middle Ages here.

Although more rare than the massive millstones, finds of wooden and iron parts of the mill machinery can also point to the existence of ancient watermills.[102] Large stone mortars have been found at many mines; their deformations suggest automated crushing mills worked by water wheels.[103]
