Sextus Julius Frontinus

Sextus Julius Frontinus

The Roman magistrate, soldier, and engineer Sextus Julius Frontinus (ca. 35-ca. 104) is known primarily as a technical writer.

Frontinus seems to have been of patrician descent, and his writings indicate that he had some knowledge of Alexandrian mathematics. In his role as magistrate, Frontinus served as praetor urbanus of Rome in the year 70 and as consul suffectus in 73. From 74 to 78 he served as governor of Britain, during which time he subdued the Silures, a powerful and warlike tribe from Wales. His instinct for public improvements, which dominated his whole career, led him to begin the construction of a public highway (Via Julia) in the conquered territory. Returning to Rome in 78, Frontinus served as consul suffectus in 98 and again in 100. It was during this latter period that most of his writings seem to have been composed.

Appointed curator aquarum (superintendent of the aqueducts) of Rome in 97, Frontinus embodied his knowledge of the water supply in a treatise, On the Aqueducts of Rome, a valuable source of information on the historical, legal, and technical life of the times. In this work Frontinus lists the names of the aqueducts, when and by whom they were constructed, and their size, height, and distribution, and he collects the many laws and penalties regulating their proper employment. The treatise portrays Frontinus as a faithful public servant who openly boasts that his reforms have made the city cleaner and the water and the air purer and removed the causes of pestilence which had formerly given Rome a bad reputation. In this work Frontinus shows himself aware of the relationship between the speed of outflow of water and its height.

Frontinus composed two treatises on military tactics. The first, The Stratagems, is a manual on military stratagems compiled from Greek and Roman military history. The book is divided into three parts—stratagems for use before the battle begins, those concerned with the battle itself, and those concerned with sieges and the raising of sieges. The other military treatise, De re militari, has not survived except in fragments quoted by other authorities.

Frontinus also composed a treatise on the art of surveying, of which only fragments are extant. It appears that this work was a pioneering effort in Roman surveying and that it was used as a standard authority for some years.

Further Reading

An early edition of Frontinus's work is The Two Books on the Water Supply of the City of Rome, translated and with explanatory chapters by Clemens Herschel (1899). A revised version of Herschel's work is The Stratagems, and the Aqueducts of Rome, edited by Mary B. McElwain (1925). Further information can be found in Thomas Ashby, The Aqueducts of Ancient Rome, edited by I. A. Richmond (1935). J. N. L. Myres, Roman Britain (1939), provides information on the political career of Frontinus as well as background information. □

Frontinus

Frontinus (Sextus Julius Frontinus) (frŏntī´nəs), fl. AD 74, Roman administrator and writer. As governor of Britain from AD 74 or AD 75 to AD 78, he reduced the Silures, a rebellious tribe in SE Wales, and pacified Britain within its borders; it was this work, successfully done, that probably rendered possible the achievements of Frontinus' successor, Agricola. From his experience as curator aquarum, or water commissioner, he wrote De aquis urbis Romae, which treats exhaustively of the water supply of Rome, with complete descriptions and history of the aqueducts. He also wrote the Strategematica, which is important as a guide to Roman military tactics and strategy.

Technical Writing. Sextus Julius Frontinus served successfully as a governor and general in Britain during the 70s C.E. In the more difficult days under the Emperor Domitian he turned to technical writing. His book on military strategy, Strategemata, survives, which collects techniques employed by military commanders throughout history, including some relatively recent ones from his own day. Only parts of his work on land surveying survive, which covered measuring, categorizing, marking of land, along with resolution of property disputes. His most famous and popular work, however, is De aquis urbis Romae (The Water Supply of Rome). In it he collects and synthesizes a vast amount of technical information about building, administering, and maintaining one of Rome’s architectural wonders, the aqueduct system. Included among his topics is keeping the system secure from those who tried to build illegal siphons into the aqueducts and acquire free water. Throughout, Frontinus displays the sort of the expertise and pride which Roman officials used to keep the empire, at its peak, running on a daily basis.
