There can be little doubt that among those parts of early Roman history which had a poetical origin was the legend of Horatius Cocles. We have several versions of the story, and these versions differ from each other in points of no small importance. Polybius, there is reason to believe, heard the tale recited over the remains of some Consul or Prætor descended from the old Horatian patricians; for he introduces it as a specimen of the narratives with which the Romans were in the habit of embellishing their funeral oratory. It is remarkable that, according to him, Horatius defended the bridge alone, and perished in the waters. According to the chronicles which Livy and Dionysius followed, Horatius had two companions, swam safe to shore, and was loaded with honors and rewards. These discrepancies are easily explained. Our own literature, indeed, will furnish an exact parallel to what may have taken place at Rome. It is highly probably that the memory of the war of Porsena was preserved by compositions much resembling the two ballads which stand first in the Relics of Ancient English Poetry. In both those ballads the English, commanded by the Percy, fight with the Scots, commanded by the Douglas. In one of the ballads the Douglas is killed by a nameless English archer, and the Percy by a Scottish spearman; in the other, the Percy slays the Douglas in single combat, and is himself made prisoner. In the former, Sir Hugh Montgomery is shot through the heart by a Northumbrian bowman; in the latter he is taken and exchanged for the Percy. Yet both the ballads relate to the same event, and that event which probably took place within the memory of persons who were alive when both the ballads were made. One of the Minstrels says:-- "Old men that knowen the grounde well yenoughe Call it the battell of Otterburn: At Otterburn began this spurne Upon a monnyn day. Ther was the dougghte Doglas slean: The Perse never went away." The other poet sums up the event in the following lines: "Thys fraye bygan at Otterborne Bytwene the nyghte and the day: Ther the Doglas lost hys lyfe, And the Percy was lede away." It is by no means unlikely that there were two old Roman lays about the defence of the bridge; and that, while the story which Livy has transmitted to us was preferred by the multitude, the other, which ascribed the whole glory to Horatius alone, may have been the favorite with the Horatian house.
