King Tarquin and his son Lucius (for he only remained to him of the three) fled to Lars Porsenna, king of Clusium, and besought him that he would help them. "Suffer not," they said, "that we, who are Tuscans by birth, should remain any more in poverty and exile. And take heed also to thyself and thine own kingdom if thou permit this new fashion of driving forth kings to go unpunished. For surely there is that in freedom which men greatly desire, and if they that be kings defend not their dignity as stoutly as others seek to overthrow it, then shall the highest be made even as the lowest, and there shall be an end of kingship, than which there is nothing more honorable under heaven." With these words they persuaded King Porsenna, who judging it well for the Etrurians that there should be a king at Rome, and that king an Etrurian by birth, gathered together a great army and came up against Rome. But when men heard of his coming, so mighty a city was Clusium in those days, and so great the fame of King Porsenna, there was such fear as had never been before. Nevertheless they were steadfastly purposed to hold out. And first all that were in the country fled into the city, and round about the city they set guards to keep it, part thereof being defended by walls, and part, for so it seemed, being made safe by the river. But here a great peril had well-nigh overtaken the city; for there was a wooden bridge on the river by which the enemy had crossed but for the courage of a certain Horatius Cocles. The matter fell out in this wise.
