The Sabines adopted the Roman months, of which whatever is remarkable is mentioned in the Life of Numa. Romulus, on the other hand, adopted their long shields, and changed his own armour and that of all the Romans, who before wore round targets of the Argive pattern. Feasts and sacrifices they partook of in common, not abolishing any which either nation observed before, and instituting several new ones; of which one was the Matronalia, instituted in honour of the women, for their extinction of the war; likewise the Carmentalia. This Carmenta some think a deity presiding over human birth; for which reason she is much honoured by mothers. Others say she was the wife of Evander, the Arcadian, being a prophetess, and wont to deliver her oracles in verse, and from carmen, a verse, was called Carmenta; her proper name being Nicostrata. Others more probably derive Carmenta from carens mente, or insane, in allusion to her prophetic frenzies. Of the feast of Palilia we have spoken before. The Lupercalia, by the time of its celebration, may seem to be a feast of purification, for it is solemnised on the dies nefasti, or non-court days, of the month February, which name signifies purification, and the very day of the feast was anciently called Februata; but its name is equivalent to the Greek Lycaea; and it seems thus to be of great antiquity, and brought in by the Arcadians who came with Evander. Yet this is but dubious, for it may come as well from the wolf that nursed Romulus; and we see the Luperci, the priests, begin their course from the place where they say Romulus was exposed. But the ceremonies performed in it render the origin of the thing more difficult to be guessed at; for there are goats killed, then, two young noblemen's sons being brought, some are to stain their foreheads with the bloody knife, others presently to wipe it off with wool dipped in milk; then the young boys must laugh after their foreheads are wiped; that done, having cut the goats' skins into thongs, they run about naked, only with something about their middle, lashing all they meet; and the young wives do not avoid their strokes, fancying they will help conception and childbirth.
Another thing peculiar to this feast is for the Luperci to sacrifice a dog. But, as a certain poet who wrote fabulous explanations of Roman customs in elegiac verses, says, that Romulus and Remus, after the conquest of Amulius, ran joyfully to the place where the wolf gave them suck; and that, in imitation of that, this feast was held, and two young noblemen ran-"Striking at all, as when from Alba town, With sword in hand, the twins came hurrying down;"and that the bloody knife applied to their foreheads was a sign of the danger and bloodshed of that day; the cleansing of them in milk, a remembrance of their food and nourishment. Caius Acilius writes, that, before the city was built, the cattle of Romulus and Remus one day going astray, they, praying to the god Faunus, ran out to seek them naked, wishing not to be troubled with sweat, and that this is why the Luperci run naked. If the sacrifice be by way of purification, a dog might very well be sacrificed, for the Greeks, in their illustrations, carry out young dogs, and frequently use this ceremony of periscylacismus, as they call it. Or if again it is a sacrifice of gratitude to the wolf that nourished and preserved Romulus, there is good reason in killing a dog, as being an enemy to wolves. Unless, indeed, after all, the creature is punished for hindering the Luperci in their running.
They say, too, Romulus was the first that consecrated holy fire, and instituted holy virgins to keep it, called vestals; others ascribe it to Numa Pompilius; agreeing, however, that Romulus was otherwise eminently religious, and skilled in divination, and for that reason carried the lituus, a crooked rod with which soothsayers describe the quarters of the heavens, when they sit to observe the flights of birds. This of his, being kept in the Palatium, was lost when the city was taken by the Gauls; and afterwards, that barbarous people being driven out, was found in the ruins, under a great heap of ashes, untouched by the fire, all things about it being consumed and burnt.
He instituted also certain laws, one of which is somewhat severe, which suffers not a wife to leave her husband, but grants a husband power to turn off his wife, either upon poisoning her children or counterfeiting his keys, or for adultery; but if the husband upon any other occasion put her away, he ordered one moiety of his estate to be given to the wife, the other to fall to the goddess Ceres; and whoever cast off his wife, to make an atonement by sacrifice to the gods of the dead. This, too, is observable as a singular thing in Romulus, that he appointed no punishment for real parricide, but called all murder so, thinking the one an accursed thing, but the other a thing impossible; and, for a long time, his judgment seemed to have been right; for in almost six hundred years together, nobody committed the like in Rome; and Lucius Hostius, after the wars of Hannibal, is recorded to have been the first parricide. Let this much suffice concerning these matters.
