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 honour 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 proper 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 bird-lime 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.
It may be observed, in general, that when young men arrive early at fame and repute, if they are of a nature but slightly touched with emulation, this early attainment is apt to extinguish their thirst and satiate their appetite; whereas the first distinctions of more and solid and weighty characters do but stimulate and quicken them and take them away like a wind in the pursuit of honour; they look upon these marks and testimonies to their virtue not as a recompense received for what they have already done, but as a pledge given by themselves of what they will perform hereafter, ashamed now to forsake or underlive the credit they have won, or, rather, not to exceed and obscure all that is gone before by the lustre of their following actions. Marcius, having a spirit of this noble make, was ambitious always to surpass himself, and did nothing how extraordinary soever, but he thought he was bound to outdo it at the next occasion; and ever desiring to give continual fresh instances of prowess, he added one exploit to another, and heaped up trophies upon trophies, so as to make it matter of contest also among his commanders, the latter still vying with the earlier, which should pay him the greatest honour and speak highest in his commendation.
Of all the numerous wars and conflicts in those days there was not one from which he returned without laurels and rewards. And, whereas others made glory the end of their daring, the end of his glory was his mother's gladness; the delight she took to hear him praised and to see him crowned, and her weeping for joy in his embraces rendered him in his own thoughts the most honoured and most happy person in the world. Epaminondas is similarly said to have acknowledged his feeling, that it was the greatest felicity of his whole life that his father and mother survived to hear of his successful generalship and his victory of Leuctra. And he had the advantage, indeed, to have both his parents partake with him, and enjoy the pleasure of his good fortune. But Marcius, believing himself bound to pay his mother Volumnia all that gratitude and duty which would have belonged to his father, had he also been alive, could never satiate himself in his tenderness and respect to her. He took a wife, also, at her request and wish, and continued, even after he had children, to live still with his mother, without parting families.
