Corculum was a talented military commander, who played a decisive role during the Battle of Pydna in 168 BC; he later won a triumph over the Dalmatae in 155 BC. He was remembered as a staunch conservative, defender of the ancestral Roman customs against political and cultural innovations, notably Hellenism, in contradiction with the policies of his famous father-in-law Scipio Africanus and cousin Scipio Aemilianus. This conservatism led him to order the destruction of the first stone theatre in Rome in 151 BC and to oppose the final war against Carthage, advocated by his rival Cato the Censor. In spite of his political influence, Corculum could not prevent the war from being voted in 149 BC, with the probable support of his cousin Scipio Aemilianus, who destroyed Carthage in 146 BC.
