Brutus saw Aruns drawing near, and he also spurred his horse forward and couched his spear.
Onward flew the two warriors until at length they met. Then each, pierced by the other’s spear, fell from his horse and moved no more.
All day the battle raged, and still when night fell the victory was uncertain.
But, during the night, while both armies were encamped on the battlefield, a loud voice was heard coming from the direction of the wood.
It was Silvanus, the god of the wood, who was speaking. ‘The victory belongs to the Romans,’ said the god, ‘for they have slain one more than their enemy.’
Obedient to the voice of Silvanus, the Etruscans on the following morning withdrew their army, while the Romans marched back to Rome.
In spite of their victory they were sad, for they carried with them the dead body of their leader.
Brutus was mourned by all the people. But the Roman matrons lamented more than others, setting aside a whole year in which to grieve for his death, because he had so bravely avenged the matron Lucretia.
