 After this failure, Tarquin turned to Lars Porsena, the king of Clusium.Porsena's march on Rome and the valiant defense of the Romans achieved legendary status, giving rise to the story of Horatius at the bridge, and the bravery of Gaius Mucius Scaevola.Accounts vary as to whether Porsena finally entered Rome, or was thwarted, but modern scholarship suggests that he was able to occupy the city briefly before withdrawing.
