Lars Tolumnius

Lars Tolumnius (Etruscan: Larth Tulumnes, d. 437 BC) was the most famous king of the wealthy Etruscan city-state of Veii. He is best remembered for instigating, and decisively losing, a war with the neighboring Roman Republic.

Background 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.

Tolumnius 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.

Marshaling his troops, the dictator fortified a position at the confluence of the Anio and the Tiber, and waited for Tolumnius to offer battle. Tolumnius, whose army was reinforced by a contingent from Falerii, was content to let the Romans make the first move, but the men of Falerii were eager for battle, so the king agreed to take the field on the following day. He sent a contingent of Veientes through the hills to attack the Romans from the rear, and the Battle of Fidenae commenced.

In recognition of his victory, the dictator Mamercus was granted a triumph, although the most famous hero of the battle was Cossus, who claimed the spolia opima, stripping the arms and armor from the fallen king, and dedicating them at the temple of Jupiter Feretrius. Meanwhile, four statues were erected on the rostra in the forum, in memory of the murdered ambassadors.
