Roman consul Agrippa Menenius Lanatus celebrates a triumph for a military victory over the Sabines.

The consuls were the two highest elected public officials of the Roman Republic. Romans considered the consulship the second-highest level of the cursus honorum—an ascending sequence of public offices to which politicians aspired—after that of the censor, which was reserved for former consuls. Each year, the centuriate assembly elected two consuls to serve jointly for a one-year term. The consuls alternated each month holding fasces when both were in Rome. A consul's imperium extended over Rome and all its provinces.

Agrippa Menenius Lanatus was a consul of the Roman Republic in 503 BC, with Publius Postumius Tubertus. He was victorious over the Sabines and was awarded a triumph which he celebrated on 4 April 503 BC. According to Livy, he also led Roman troops against the Latin town of Pometia. In some traditions he and his colleague also completed a census during their consulship.

The Roman triumph was a civil ceremony and religious rite of ancient Rome, held to publicly celebrate and sanctify the success of a military commander who had led Roman forces to victory in the service of the state or, in some historical traditions, one who had successfully completed a foreign war.

The Sabines were an Italic people who lived in the central Apennine Mountains of the ancient Italian Peninsula, also inhabiting Latium north of the Anio before the founding of Rome.

April 4 is the 94th day of the year in the Gregorian calendar; 271 days remain until the end of the year.
