Sextus Julius Frontinus

Sextus Julius Frontinus (c. 40 – 103 AD) was one of the most distinguished Roman senators of the late 1st century AD. He is best known to the post-Classical world as an author of technical treatises, especially De aquaeductu, dealing with the aqueducts of Rome.

In AD 70, he participated in the suppression of the Rhineland revolt, and later recorded that he received the surrender of 70,000 Lingones. Between that date and being appointed governor of Britain to succeed Quintus Petillius Cerialis a few years later, Frontinus was appointed suffect consul. While governor of Britain, he subjugated the Silures of South Wales and is thought to have likewise campaigned against the Brigantes. He was succeeded by Gnaeus Julius Agricola, the father-in-law of the famous historian Tacitus, in 77. Birley believes it "is fair to speculate" that Frontinus was with Domitian during the German campaign of 83. An inscription at Hieropolis in Phrygia, as well as a number of coins of Smyrna, attests that he was proconsul of Asia in AD 86.

In 97, he was appointed Water Commissioner of the aqueducts (curator aquarum) at Rome by the emperor Nerva, an office only conferred upon persons of very high standing. He was also a member of the College of Augurs. In this capacity, he followed another distinguished Roman statesman, Agrippa, the friend, ally and son-in-law of Augustus, who organised in 34 BC a campaign of public repairs and improvements, including renovation of the aqueduct Aqua Marcia and an extension of its pipes to cover more of the city.
