The one which Laenas waged against the Tiburtines presented little difficulty; after driving them into their city he ravaged their fields. The other consul, who was operating against the Faliscans and Tarquinians, met with a defeat in the first battle.
What mainly contributed to it and produced a real terror amongst the Romans was the extraordinary spectacle presented by their priests who, brandishing lighted torches and with what looked like snakes entwined in their hair, came on like so many Furies.
At this sight the Romans were like men distraught or thunderstruck and rushed in a panic-stricken mass into their entrenchments. The consul and his staff officers and the military tribunes laughed at them and scolded them for being terrified by conjuring tricks like a lot of boys.
