(consul 43 bc), since c.54 an officer of Caesar, who sent him as envoy to Pompey in December 50. In the Civil Wars he served in Spain, and was at Antioch in spring 47; in 46 he was praetor and next year governed Transalpine Gaul. After Caesar's murder he was consul designate, and Cicero induced him to take up arms against Antony (Marcus Antonius) (43). With Octavian he raised Antony's siege of Mutina, but was killed in the victory, receiving with his colleague Pansa a public funeral. Hirtius added to Caesar's Gallic War an eighth book, and probably also wrote the Alexandrian War; his correspondence with Cicero, published in nine books, and the draft for Caesar's Anticato have not survived. A notorious epicure, Hirtius was also a fluent and reasonably painstaking writer.
