The patrician house of the Marcii in Rome produced many men of distinction, and among the rest, Ancus Marcius, grandson to Numa by his daughter, and king after Tullus Hostilius. Of the same family were also Publius and Quintus Marcius, which two conveyed into the city the best and most abundant supply of water they have at Rome. As likewise Censorinus, who, having been twice chosen censor by the people, afterwards himself induced them to make a law that nobody should bear that office twice. But Caius Marcius, of whom I now write, being left an orphan, and brought up under the widowhood of his mother, has shown us by experience, that, although the early loss of a father may be attended with other disadvantages, yet it can hinder none from being either virtuous or eminent in the world, and that it is no obstacle to true goodness and excellence; however bad men may be pleased to lay the blame of their corruptions upon that misfortune and the neglect of them in their minority. Nor is he less an evidence to the truth of their opinion, who conceive that a generous and worthy nature without proper discipline, like a rich soil without culture, is apt, with its better fruits, to produce also much that is bad and faulty. While the force and vigor of his soul, and a persevering constancy in all he undertook, led him successfully into many noble achievements, yet, on the other side, also, by indulging the vehemence of his passion, and through all obstinate reluctance to yield or accommodate his humors and sentiments to those of people about him, he rendered himself incapable of acting and associating with others. Those who saw with admiration how proof his nature was against all the softnesses of pleasure, the hardships of service, and the allurements of gain, while allowing to that universal firmness of his the respective names of temperance, fortitude, and justice, yet, in the life of the citizen and the statesman, could not choose but be disgusted at the severity and ruggedness of his deportment, and with his overbearing, haughty, and imperious temper. Education and study, and the favors of the muses, confer no greater benefit on those that seek them, than these humanizing and civilizing lessons, which teach our natural qualities to submit to the limitations prescribed by reason, and to avoid the wildness of extremes.

Those were times at Rome in which that kind of worth was most esteemed which displayed itself in military achievements; one evidence of which we find in the Latin word for virtue, which is properly equivalent to manly courage. As if valor and all virtue had been the same thing, they used as the common term the name of the particular excellence. But Marcius, having a more passionate inclination than any of that age for feats of war, began at once, from his very childhood, to handle arms; and feeling that adventitious implements and artificial arms would effect little, and be of small use to such as have not their native and natural weapons well fixed and prepared for service, he so exercised and inured his body to all sorts of activity and encounter, that, besides the lightness of a racer, he had a weight in close seizures and wrestlings with an enemy, from which it was hard for any to disengage himself; so that his competitors at home in displays of bravery, loath to own themselves inferior in that respect, were wont to ascribe their deficiencies to his strength of body, which they said no resistance and no fatigue could exhaust.

The first time he went out to the wars, being yet a stripling, was when Tarquinius Superbus, who had been king of Rome and was afterwards expelled, after many unsuccessful attempts, now entered upon his last effort, and proceeded to hazard all as it were upon a single throw. A great number of the Latins and other people of Italy joined their forces, and were marching with him toward the city, to procure his restoration; not, however, so much out of a desire to serve and oblige Tarquin, as to gratify their own fear and envy at the increase of the Roman greatness, which they were anxious to check and reduce. The armies met and engaged in a decisive battle, in the vicissitudes of which, Marcius, while fighting bravely in the dictator's presence, saw a Roman soldier struck down at a little distance, and immediately stepped in and stood before him, and slew his assailant. The general, after having gained the victory, crowned him for this act, one of the first, with a garland of oaken branches; it being the Roman custom thus to adorn those who had saved the life of a citizen; whether that the law intended some special honor to the oak, in memory of the Arcadians, a people the oracle had made famous by the name of acorn-eaters; or whether the reason of it was because they might easily, and in all places where they fought, have plenty of oak for that purpose; or, finally, whether the oaken wreath, being sacred to Jupiter, the guardian of the city, might, therefore, be thought a propel ornament for one who preserved a citizen. And the oak, in truth, is the tree which bears the most and the prettiest fruit of any that grow wild, and is the strongest of all that are under cultivation; its acorns were the principal diet of the first mortals, and the honey found in it gave them drink. I may say, too, it furnished fowl and other creatures as dainties, in producing mistletoe for birdlime to ensnare them. In this battle, meantime, it is stated that Castor and Pollux appeared, and, immediately after the battle, were seen at Rome just by the fountain where their temple now stands, with their horses foaming with sweat, and told the news of the victory to the people in the Forum. The fifteenth of July, being the day of this conquest, became consequently a solemn holiday sacred to the Twin Brothers.
