All four were murdered on the orders of the Veientine king, Lars Tolumnius.
To honor their sacrifice for the Republic, the Romans later erected half-sized statues of Gaius Fulcinius and his colleagues Tullus Cloelius, Spurius Antius, and Lucius Roscius on the Rostra, in the Roman Forum.
The Fidenese leaders of the revolution offered Tolumnius control over their city, which the king gladly accepted, and when Rome sent the four emissaries (Tullus Cloelius, Gaius Fulcinius, Spurius Antius, and Lucius Roscius) to Veii to demand the hegemony of Fidenae back, Tolumnius had them executed.
