Then Marcus Valerius, the brother of Publius, levelled his lance and rode fiercely against Titus Tarquinius, who was the leader of the band of the Tarquinii. But Titus drew back, and sheltered himself amidst his band: and Marcus rode after him in his fury, and plunged into the midst of the enemy, and a Latin ran his lance into his side as he was rushing on; but his horse stayed not in his career, till Marcus dropped from him dead upon the ground. Then the Romans feared yet more, and the Tarquinii charged yet more vehemently, till Aulus, the leader of the Romans, rode up with his own chosen band; and he bade them level their lances, and slay all whose faces were towards them, whether they were friends or foes. So the Romans turned from their flight, and Aulus and his chosen band fell upon the Tarquinii; and Aulus prayed, and vowed that he would raise a temple to Castor and to Pollux, the twin heroes, if they would aid him to win the battle; and he promised to his soldiers that the two who should be the first to break into the camp of the enemy should receive a rich reward. When behold there rode two horsemen at the head of his chosen band, and they were taller and fairer than after the stature and beauty of men, and they were in the first bloom of youth, and their horses were white as snow. Then there was a fierce battle, when Octavius, the leader of the Latins, came up with aid to rescue the Tarquinii; for Titus Herminius rode against him, and ran his spear through his body, and slew him at one blow; but as he was spoiling him of his arms, he himself was struck by a javelin, and he was borne out of the fight and died. And the two horsemen on white horses rode before the Romans; and the enemy fled before them, and the Tarquinii were beaten down and slain, and Titus Tarquinius was slain among them; and the Latins fled, and the Romans followed them to their camp, and the two horsemen on white horses were the first who broke into the camp. But when the camp was taken, and the battle was fully won, Aulus sought for the two horsemen to give them the rewards which he had promised; and they were not found either amongst the living or amongst the dead, only there was seen imprinted on the hard black rock, the mark of a horse’s hoof, which no earthly horse had ever made; and the mark was there to be seen in after ages. And the battle was ended, and the sun went down.
