According to Wikipedia: "Titus Livius (59 BC – AD 17) — known as Livy in English — was a Roman historian who wrote a monumental history of Rome and the Roman people. Ab Urbe Condita Libri, "Books from the Foundation of the City," covering the period from the earliest legends of Rome well before the traditional foundation in 753 BC through the reign of Augustus in Livy's own time." "The Discourses on Livy (Italian: Discorsi sopra la prima deca di Tito Livio, literally "Discourses on the First Decade of Titus Livy") is a work of political history and philosophy written in the early 16th century (ca. 1517) by the Italian writer and political theorist Niccolò Machiavelli, best known as the author of The Prince. Where the latter is nominally devoted to advising the ruler of a principality, in other words a type of monarchy, the Discourses purport to explain the structure and benefits of a republic, a form of government based on some level of popular consent and control."
