The first battle was indecisive, with heavy losses on both sides. The enemy then withdrew into their camp, affording the Romans an opportunity to renew their preparations for the war. Tarquinius believed that cavalry was what he chiefly lacked. To the Ramnes, Titienses, and Luceres, the centuries which Romulus had enrolled, he therefore determined to add others, and to give them his own name as a permanent distinction.  But since this was a matter in which Romulus had obtained the sanction of augury before acting, it was asserted by Attus Navius, a famous augur of those days, that no change or innovation could be introduced unless the birds had signified their approval.  The king's ire was aroused by this, and he is reported to have said, in derision of the science, “Come now, divine seer! Inquire of your augury if that of which I am now thinking can come to pass.” When Attus, having taken the auspices, replied that it would surely come to pass, the king said, “Nay, but this is what I was thinking of, that you should cleave a whetstone with a razor. Take them, and accomplish what your birds declare is possible!” Whereupon, they say, the augur, without a sign of hesitation, cut the whetstone in two.  There was a statue of Attus standing, with his head covered, on the spot where the thing was done, in the comitium, even at the steps on the left of the senate-house; tradition adds that the whetstone also was deposited in the same place, to be a memorial of that miracle to posterity.
