Sextus Julius Frontinus (c. 40 – 103 AD) was a Roman civil engineer, author, soldier and senator of the late 1st century AD. He was a successful general under Domitian, commanding forces in Roman Britain, and on the Rhine and Danube frontiers. A novus homo, he was consul three times. Frontinus ably discharged several important administrative duties for Nerva and Trajan. However, he is best known to the post-Classical world as an author of technical treatises, especially De aquaeductu, dealing with the aqueducts of Rome.

Sextus Julius Frontinus in the context of De aquaeductu
De aquaeductu (English: On aqueducts) is a two-book official report given to the emperor Nerva or Trajan on the state of the aqueducts of Rome, and was written by Sextus Julius Frontinus at the end of the 1st century AD. It is also known as De Aquis or De Aqueductibus Urbis Romae. It is the earliest official report of an investigation made by a distinguished citizen on Roman engineering works to have survived. Frontinus had been appointed Water Commissioner by the emperor Nerva in AD 96.
With the recovery of Frontinus' manuscript from the library at Monte Cassino in 1425, effected by the tireless humanist Poggio Bracciolini, details of the construction and maintenance of the Roman aqueduct system became available once more, just as Renaissance Rome began to revive and require a dependable source of pure water.
