In 56 BC, the Roman army laid siege to Larignum. Vitruvius stands as the only surviving source for this specific battle. He served as an artilleryman within the Roman military structure known as the third class of arms. His role involved constructing ballista and scorpio war machines designed for sieges. These weapons required precise engineering to function during combat operations. He likely worked alongside Lucius Cornelius Balbus, the chief engineer under Julius Caesar. Their work took them across north Africa, Hispania, Gaul, and Pontus. At Avaricum in 52 BC, forty thousand residents faced a massacre ordered by Roman forces. Vercingetorix noted that Romans conquered through skill rather than raw valor. The siege at Gergovia ended in failure for the Roman legions. Later, at Alesia, women and children were evicted from the city walls to conserve food supplies. They starved to death between opposing fortifications. Vitruvius documented these events while serving with Legio VI Ferrata. This legion included auxiliary units equipped with ballistae. He described battles at Dyrrhachium, Pharsalus, Zela, and Thapsus. Each location represents a chapter in his military career spanning decades.
Ten Books On Architecture
Vitruvius dedicated his treatise De architectura to Emperor Augustus. The work survives today as the only major book on architecture from classical antiquity. It consists of ten volumes written in Latin. Book I addresses the education of an architect who must master drawing, geometry, optics, history, philosophy, music, theatre, medicine, and law. Book III discusses human proportions inscribed within a circle and square. Renaissance artists later used this text to create famous illustrations like Leonardo da Vinci's Vitruvian Man. The original Greek texts influenced Vitruvius' compilation of rules. He recorded elaborate sets of guidelines taken from earlier authors over preceding centuries. His dedication to Augustus aimed to provide personal knowledge about building quality. Frontinus referenced Vitruvius regarding standard pipe sizes for aqueducts. The text remained well known throughout the Middle Ages despite its age. Dozens of manuscripts survived until 1414 when Poggio Bracciolini rediscovered it in Saint Gall Abbey. Translations followed into Italian, French, English, German, and Spanish. Fra Giovanni Giocondo published the first illustrated edition in Venice during 1511 using woodcuts based on textual descriptions.
