A chain of events—unrelated yet not accidental—led to the Roman patrician Mark Sidonius Falx compiling this manual and guide for an antique top manager. In all ages (and from the times described in the book, more than two millennia separate us) the main thing in the art of managing is managing people. Falx’s work is dedicated to precisely this, and the wisdom of the Roman is useful to us, even though most workers’ relationships with most employers have changed significantly. A modern leader is unlikely to find knowledge about where in the Italian capital to buy eunuch employees—and how, when hiring, to distinguish a candidate who has been starved for a long time from a well-fed and healthy one captured after losing a battle. Every word, every detail in the author’s narration (from the Roman’s perspective, Falx wrote the book down, and a well-known British historian, Jerry Toner, recorded it) has been verified against dozens of historical sources—from Aristotle to Cato.
