The principal distinction between the lay of Horatius and the lay of the Lake Regillus is that the former is meant to be purely Roman, while the latter, though national in its general spirit, has a slight tincture of Greek learning and of Greek superstition. The story of the Tarquins, as it has come down to us, appears to have been compiled from the works of several popular poets; and one, at least, of those poets appears to have visited the Greek colonies in Italy, if not Greece itself, and to have had some acquaintance with the works of Homer and Herodotus. Many of the most striking adventures of the House of Tarquin, before Lucretia makes her appearance, have a Greek character. The Tarquins themselves are represented as Corinthian nobles of the great House of the Bacchiadæ, driven from their country by the tyranny of that Cypselus, the tale of whose strange escape Herodotus has related with incomparable simplicity and liveliness. Livy and Dionysius tell us that, when Tarquin the Proud was asked what was the best mode of governing a conquered city, he replied only by beating down with his staff all the tallest poppies in his garden. This is exactly what Herodotus, in the passage to which reference has already been made, relates of the counsel given to Periander, the son of Cypselus. The stratagem by which the town of Gabii is brought under the power of the Tarquins is, again, obviously copied from Herodotus. The embassy of the young Tarquins to the oracle at Delphi is just such a story as would be told by a poet whose head was full of the Greek mythology; and the ambiguous answer returned by Apollo is in the exact style of the prophecies which, according to Herodotus, lured Croesus to destruction. Then the character of the narrative changes. From the first mention of Lucretia to the retreat of Porsena nothing seems to be borrowed from foreign sources. The villainy of Sextus, the suicide of his victim, the revolution, the death of the sons of Brutus, the defence of the bridge, Musius burning his hand, Cloelia swimming through Tiber, seem to be all strictly Roman. But when we have done with the Tuscan wars, and enter upon the war with the Latines, we are again struck by the Greek air of the story. The Battle of the Lake Regillus is in all respects a Homeric battle, except that the combatants ride astride on their horses, instead of driving chariots. The mass of fighting men is hardly mentioned. The leaders single each other out, and engage hand to hand. The great object of the warriors on both sides is, as in the Iliad, to obtain possession of the spoils and bodies of the slain; and several circumstances are related which forcibly remind us of the great slaughter round the corpses of Sarpedon and Patroclus.
