The Romans had a citadel on the Capitoline Hill, and Tatius desired to win it. The guardian was named Tarpeius, and he had a daughter, Tarpeia, who was so much attracted by the golden ornaments worn by the Sabines, that she promised to open the citadel to them if each soldier would give his bracelet to her. This was promised, and as each entered he threw his golden ornament upon the poor maiden, until she fell beneath the weight and died, for they wished to show that they hated treachery though willing to profit by it. Her name was fixed upon the steep rock of the Capitoline Hill from which traitors were in after years thrown. We now have the Sabines on one hill and the Romans on another, with a swampy plain of small extent between them, where the forum was afterward built. The Romans wished to retake the Capitoline Hill (which was also called the Hill of Saturn), and a battle was fought the next day in the valley. It is said that two men began the fight, Mettus Curtius, representing the Sabines, and Hostus Hostilius, the Romans, and that though the Roman was killed, Curtius was chased into the swamp, where his horse was mired, and all his efforts with whip and spur to get him out proving ineffectual, he left the faithful beast and saved himself with difficulty. The swamp was ever after known as _Lacus Curtius_, and this story might be taken as the true origin of its name (for _lacus_ in Latin meant a marsh as well as a lake), if it were not that there are two other accounts of the reason for it. One story is that in the year 362 B.C.--that is, some four centuries after the battle we have just related, the earth in the forum gave way, and all efforts to fill it proving unsuccessful, the oracles were appealed to. They replied that the spot could not be made firm until that on which Rome's greatness was based had been cast into the chasm, but that then the state would prosper. In the midst of the doubting that followed this announcement, the gallant youth, Curtius, came forward, declaring that the city had no greater treasure than a brave citizen in arms, upon which he immediately leaped into the abyss with his horse. Thereupon the earth closed over the sacrifice. This is the story that Livy prefers. The third is simply to the effect that while one Curtius was consul, in the year 445 B.C., the earth at the spot was struck by lightning, and was afterwards ceremoniously enclosed by him at the command of the senate. This is a good example of the sort of myth that the learned call _ætiological_--that is, myths that have grown up to account for certain facts or customs. The story of the carrying off of the Sabine women is one of this kind, for it seems to have originated in a desire to account for certain incidents in the marriage ceremonies of the Romans. We cannot believe either, though it is reasonable to suppose that some event occurred which was the basis of the tradition told in connection with the history of different periods.
