Watermill Windmill

Rome (750 B.C. – 500 A.D.): 

Rome (750 B.C. – 500 A.D.) Sophisticated agriculture Laws of individual ownership Advanced stone masonry technology Road building exceeded only in 19th century Military engineering, civil engineering Spinning and weaving Mechanical reaper (forgotten in dark ages) First to build amphitheatre, aquaducts, public baths Stone bridges, vaults and domes

Rome (cont’d): 

Rome (cont’d) Concentrated sand which contained cystalline grains and some buildings have lasted over 2,000 years Urban Roman life included multi storey apartment blocks street paving, public flush toilets, glass windows and floor and wall heating Some technologies lost in middle ages and reinvented in 19th and 20th centuries
