He also did great works in peace; for he made vast drains to carry off the water from between the Palatine and the Aventine, and from between the Palatine and the Capitoline hills. And in the space between the Palatine and the Aventine, after he had drained it, he formed the Circus, or great race-course, for chariot and for horse races. Then in the space between the Palatine and the Capitoline he made a forum or market-place, and divided out the ground around it for shops or stalls, and made a covered walk round it. Next he set about building a wall of stone to go round the city; and he laid the foundations of a great temple on the Capitoline Hill, which was to be the temple of the gods of Rome. He also added a hundred new senators to the senate, and doubled the number of the horsemen in the centuries of the Ramnes, Tities, and Luceres, for he wanted to strengthen his force of horsemen; and when he had done so, his horse gained him great victories over his enemies. Now he first had it in his mind to make three new centuries of horsemen, and to call them after his own name. But Attus Navius, who was greatly skilled in augury, forbade him. Then the king mocked at his art, and said, “Come now, thou augur, tell me by thy auguries, whether the thing which I now have in my mind may be done or not.” And Attus Navius asked counsel of the gods by augury, and he answered, “It may.” Then the king said, “It was in my mind that thou shouldst cut in two this whetstone with this razor. Take them, and do it, and fulfil thy augury if thou canst.” But Attus took the razor and the whetstone, and he cut, and cut the whetstone asunder. So the king obeyed his counsels, and made no new centuries; and in all things afterwards he consulted the gods by augury, and obeyed their bidding.
