Sextus Iulius Frontinus (c. 35-103) describes the origin of the aqueducts of the city of Rome as well as their sources. The standardization of pipe sizes for the pipes and precise measurements of inflows and outflows are particularly important to him. He also deals with the distribution of water and the improvement of water quality. The copper shows, among other things, architectural representations of water pipes and various plans with the course of the line. Frontinus was commander in the Roman army, governor in Britain and consul. From 97 he was Curator Aquarum, supervising the water supply in Rome. Edited and commented "with excellent grades" (Ebert), this edition was edited by Italian mathematician Giovanni Poleni (1683-1761), who taught astronomy and physics at the University of Padua. – The double-leaf text copper is missing.
