The war that followed was marked by two romantic incidents. Near the Tiber is a hill,--afterwards known as the Capitoline Hill,--which was divided from the Palatine Hill by a low and swampy valley. On this hill Romulus had built a fortress, as a sort of outwork of his new city. It happened that Tarpeius, the chief who held this fortress, had a daughter named Tarpeia, who was deeply affected by that love of finery which has caused abundant mischief since her day. When she saw the golden collars and bracelets which many of the Sabines wore, her soul was filled with longing, and she managed to let them know that she would betray the fortress into their hands if they would give her the bright things which they wore upon their arms. They consented, and she secretly opened to them a gate of the fortress. But as they marched through the gate, and the traitress waited to receive her reward, the Sabine soldiers threw on her the bright shields which they wore on their arms, and she was crushed to death beneath their weight. The steep rock of the Capitoline Hill from which traitors were afterwards thrown was called, after her, the Tarpeian Rock. [Illustration: ROME FROM THE DOME OF ST. PETER'S.] The fortress thus captured, the valley between the hill and the city became the scene of battle. Here the Sabines repulsed the Romans, driving them back to one of their gates, through which the fugitives rushed in confusion, shutting it hastily behind them. But--if we may trust the legend--the gate refused to stay shut. It opened again of its own accord. They closed it twice more, and twice more it swung open. The victorious Sabines, who had now reached it, began to rush in; but just then, from the Temple of Janus, near by, there burst forth a mighty stream of water, which swept the Sabines away and saved Rome from capture. Therefore, in after-days, the gates of the Temple of Janus stood always wide open in time of war, that the god might go out, if he would, to fight for the Romans. Another battle took place in the valley, and the Romans again began to flee. Romulus now prayed to Jupiter, and vowed to erect to him a temple as Jupiter Stator,--that is, the "stayer,"--if he would stay the Romans in their flight. Jupiter did so, or, at any rate, the Romans turned again to the fight, which now waxed furious. What would have been its result we cannot tell, for it was brought to an end by the other romantic incident of which we have spoken. In fact, while the fathers of the Sabine virgins retained their anger against the Romans, the virgins themselves, who had now long been brides, had become comforted, most of them being as attached to their husbands as they had been to their parents before; and in the midst of the furious battle between their nearest relatives the lately abducted damsels were seen rushing down the Palatine Hill, and forcing their way, with appealing eyes and dishevelled hair, in between the combatants.
