Tullus Hostilius, the third king of Rome, said to have reigned from about 673 to about 641 B. C. The most memorable event of his reign, according to the legend, is the war with Alba, celebrated by the combat between the Horatii and the Curiatii, and the consequent acknowledgment by the Albans of Roman supremacy. In the war against Fidenae, an Al-ban army was led to the assistance of Rome by Mettus Fuffetius, the Alban dictator, who intended to go over to the enemy at the critical moment. Tullus discovered the treachery, had the traitor torn in pieces from chariot wheels, razed Alba to the ground, and transferred the inhabitants to Rome, where the great mass of them became the Roman plebs. After these successes Rome was afflicted with a pestilence, and the king himself was seized with the disease. Having found the formula with which Numa had sacrificed to Jupiter Elicius, he attempted to call down the god, but fell into an error, and the god destroyed the king and his household by lightning.
