Lars Tolumnius

Lars Tolumnius (Etruscan: Larth Tulumnes, d. 437 BC), was the most famous king of the wealthy Etruscan city-state of Veii, roughly ten miles northwest of Rome, best remembered for instigating a war with Rome that ended in a decisive Roman victory.

Very little is known of Tolumnius outside of his involvement in Roman legend. His family was evidently part of the Veientine aristocracy, and its nomen is found on a number of inscriptions from votive offerings.

Tolumius enters history when the Roman colony of Fidenae revolted against the Republic in 438 BC, and allied itself with Veii, giving Tolumnius control of the Fidenate army. The Romans sent four envoys (Tullus Cloelius, Gaius Fulcinius, Spurius Antius, and Lucius Roscius) to Fidenae to demand an explanation, but they were murdered by the Fidenates, apparently on the king's orders.

A popular story held that Tolumnius had not intended this breach of decorum: supposedly he was playing at dice when the Fidenates asked whether they should kill the ambassadors, and having just rolled fortuitously, the king exclaimed, "excellent!", which the Fidenates interpreted as an order to put the Romans to death. Livy is skeptical of this tradition, disbelieving that Tolumnius would have allowed himself to become so easily distracted on an occasion of such importance. Rather, he suggests, Tolumnius intended the execution of the emissaries to involve the Fidenates in a deed that would make it impossible for them to repair the breach with Rome.

Outraged by Tolumnius' actions, the Roman Senate declared war against Veii, and the following year dispatched a consular army under the command of Lucius Sergius, which met Tolumnius and the Fidenates south of the Anio. Sergius won the day despite brutal fighting, and earned the surname Fidenas, but the Roman losses were so high that a state of emergency was declared, and the Senate appointed Mamercus Aemilius Mamercinus dictator to meet the threat posed by Tolumnius' forces.
