d. 104
A Roman senator, general, and engineer, this practical-minded writer is best remembered for books that turn warfare and public works into vivid, usable knowledge. His surviving works offer a rare close-up view of how Rome fought, planned, and kept a vast city running.

by Sextus Julius Frontinus

Living in the late 1st century AD, Frontinus built a remarkable career in public life as a soldier, senator, and administrator. Ancient and modern sources alike remember him as a successful general in Roman Britain and later as a trusted official under emperors including Nerva and Trajan.
He is especially famous today for De aquis urbis Romae, a detailed account of Rome’s aqueduct system. That work is valuable not just for its engineering detail, but for the clear, practical way it shows how Roman government managed water, maintenance, and urban life.
Frontinus also wrote the Strategemata, a collection of military examples and tactics drawn from earlier history. Together, his books have kept his name alive as one of the most readable Roman authors on strategy, infrastructure, and the everyday mechanics of empire.
