Water-Powered Mills

Timeline

1. c. -100–400Mediterranean region · MediterraneanVitruvius described horizontal water wheel mills in De Architectura, and the Roman Empire built large mill complexes at places like Barbegal; China's Han dynasty also has documentary records of water mills, marking the independent origins of hydraulic technology.
2. c. 900–1300Western Europe · Western EuropeThe Domesday Book (1086) records over 5,600 water mills in England; monasteries actively promoted water mill technology, and cam and gear transmission techniques for vertical water wheel mills continued to improve, with hydraulic applications expanding from grain grinding to industrial production such as iron forging and fulling.
3. 1400–1500Europe and East Asia · AsiaIn the 1451–1460s, water-powered mills were the primary power source for grain processing throughout Europe; Ming China and the Ottoman Empire also made extensive use of water power to drive mills and metalworking at the same time, with hydraulic technology becoming the core infrastructure of agricultural civilizations.
