His forces were held off at the Pons Sublicius by Horatius Cocles.
He's not Servius Tullius, but this leader was syncretized with the Etruscan hero Mastarna whom the wall-paintings of Vulci attest as rescuing Caelius Vibenna and killing the Tarquins. One person who confronted him stated that he was the first of three hundred who had volunteered for suicide missions to assassinate him, and along with his son Arruns he attacked the city of Aricia but was defeated by the Latin League. In another story a female hostage who escaped from his camp by swimming across a river amidst a hail of spears later returned to captivity as a matter of honor. Her name was Cloelia. Another story about him includes a young Roman named Mucius Scaevola holding his hand inside a fire to demonstrate his determination to defeat him, after which he broke off his siege of Rome. His forces were held off at the Pons Sublicius by Horatius Cocles. For 10 points, name this legendary Etruscan king of Clusium, a frequent antagonist of Rome in the early days of the Republic.
