Frontinus

Sextus Julius Frontinus (ca. 40–103 AD) was one of the most distinguished Roman aristocrats of the late 1st century AD: he was grandson of Aulus Julius Frontinus and Cornelia Africana, the only child of Publius Cornelius Scipio. He is best known to the post-Classical world as an author of technical treatises, especially one dealing with the aqueducts of Rome.
