After this King Ancus died, having reigned twenty and four years, and left two sons, not yet old enough to reign, yet nearly grown to manhood. And some would have delayed the choosing of a king till these should be come to full age, but Tarquinius counselled that he should be chosen forthwith. And when the day for this choosing was appointed, having sent out the lads to hunt, he spake to the people after this manner. "This is no new thing that I seek the kingdom at your hands; for Tatius the Sabine became your king, having been before not a stranger only but also an enemy; and Numa also was called to this dignity, though he sought not for it. As for me, I came hither so soon as I was master of myself; and of the years of my manhood, I have lived in Rome more than in my own country; nor have I been ill taught the ways of a King, ministering to Ancus both at home and abroad."
With these words he persuaded the people that they chose him to be king. Being so chosen he did many things that pleased the people; for having waged war with the Latins, and taken one of their cities and with it much booty, he built the great circus, and fetched horses and boxers from the land of Etruria to make sport. This became a custom year by year; and they called these games the Great Games of Rome.
Afterwards he would have compassed the city with a wall of stone; but while he was busy with the building of it the Sabines came upon him. And this they did with such speed that they had crossed the Anio before ever the Romans were ready to meet them; and when they fought many were slain on both sides, but neither had the victory. Now when the King, the enemy having returned to their camp, had space to consider how he might best make his army the stronger, it seemed that it would profit him most if he should increase the number of his horsemen, of whom there were three companies only. But when he was minded to add others to them, and to call them after his own name, one Attus Navius, that was a famous soothsayer in those days, withstood him. "For," said he, "King Romulus made these companies in due form, and thou mayest not add to their number, unless the gods permit, signifying their will by the voices of birds." But the King was wroth to hear these words, and mocked the soothsayers art, saying, "Come now, thou wise man, divine unto me, can that which I think in my heart be done, or no?" Attus answered, having first made trial of his art, "Of a surety it can be done." Then said the King, "I thought this thing in my heart, that thou shouldest cut asunder this whetstone with a razor. Take it, therefore, and cut it asunder; for thy birds will have it that thou canst." And straightway Attus took the whetstone and cut it asunder. So they made a statue of him, standing with his head covered, in the place where the thing was done; even in the place of assembly, on the right hand of the steps by which a man goes up to the senate-house. And by his side they laid the stone to be a memorial of this miracle to them that should come after. Certainly there came such honour to the soothsayers that nothing thereafter was done at home or abroad except they first allowed it; and if an assembly of the people was called or the army gathered together, it must be dispersed again unless the birds should signify that it was according to the pleasure of the gods. King Tarquin, therefore, changed not the number or the name of the companies. Only he added to each as many more horsemen as it had at the first.
