For the more famous Latin poet, see Catullus.Quintus Lutatius Catulus (149-87 BC) was consul of the Roman Republic in 102 BC, and the leading public figure of the gens Lutatia of the time. His colleague in the consulship was Gaius Marius, but the two feuded and Catulus sided with Sulla in the civil war of 88–87 BC. When the Marians regained control of Rome in 87, Catulus committed suicide rather than face prosecution.
