Marcus Porcius Cato, also known as Cato the Censor, the Elder and the Wise, was a Roman soldier, senator, and historian known for his conservatism and opposition to Hellenization. He was the first to write history in Latin with his Origines, a now fragmentary work on the history of Rome. His work De agri cultura, a rambling work on agriculture, farming, rituals, and recipes, is the oldest extant prose written in the Latin language. His epithet "Elder" distinguishes him from his great-grandson Cato the Younger, who opposed Julius Caesar.

Marcus Porcius Cato Uticensis, also known as Cato the Younger, was an influential conservative Roman senator during the late Republic. His conservative principles were focused on the preservation of what he saw as old Roman values in decline. A noted orator and a follower of Stoicism, his scrupulous honesty and professed respect for tradition gave him a powerful political following which he mobilised against powerful generals of his day, including Julius Caesar and Pompey.
