The Greek historian Dionysius of Halicarnassus describes him as a highly decorated revolutionary who was involved in the expulsion of Rome's last king Lucius Tarquinius Superbus.
He was a suffect consul in the first year of the Republic in 509 BC, elected to replace Spurius Lucretius Tricipitinus who died in office.
His colleague was Publius Valerius Publicola, with whom he also held his second consulship in 507 BC.
[citation needed] Horatius consecrated the newly built Temple of Jupiter Optimus Maximus on the Capitoline Hill during his first consulship in 509 BC.
[4] His surname appears as Pulvillus for the first time in Cicero's treatise De Domo Sua.
