Sextus Julius Frontinus (c. A.D. 35—103) was one of the most capable administrators in the Roman Empire’s long history. During his distinguished career, he served at least six emperors in a variety of prestigious offices, including general, consul, governor, proconsul of Asia, and supervisor of aqueducts. He may have been the longest-serving Roman governor of Britain, a position he held for five years.

Frontinus’s military handbook, Stratagems, was likely composed towards the end of the first century A.D. Intended as a practical manual for military leaders, and drawing from the rich history of Greece and Rome, Stratagems offers a wealth of tactical ruses, ploys, and maneuvers that have been used to gain victory. His focus is entirely practical: what must a leader do to win? Because Frontinus grasps the psychological and moral factors of conflict, his work retains a timeless importance that modern readers will find applicable to nearly every field of endeavor.

This new, annotated translation by Quintus Curtius returns to the original Latin text to present Frontinus in a contemporary idiom to a modern audience. Containing an explanatory introduction, a discussion of the text, hundreds of footnotes, a bibliography, and an extensive index, this translation aims to assist a new generation of readers in rediscovering an essential classic of strategic thought.
