+35.+ This event conveys many useful lessons to a thoughtful observer. Above all, the disaster of Regulus gives the clearest possible warning that no one should feel too confident of the favours of Fortune, especially in the hour of success. Here we see one, who a short time before refused all pity or consideration to the fallen, brought incontinently to beg them for his own life. Again, we are taught the truth of that saying of Euripides— One wise man’s skill is worth a world in arms. For it was one man, one brain, that defeated the numbers which were believed to be invincible and able to accomplish anything; and restored to confidence a whole city that was unmistakably and utterly ruined, and the spirits of its army which had sunk to the lowest depths of despair. I record these things in the hope of benefiting my readers. There are two roads to reformation for mankind—one through misfortunes of their own, the other through those of others: the former is the most unmistakable, the latter the less painful. One should never therefore voluntarily choose the former, for it makes reformation a matter of great difficulty and danger; but we should always look out for the latter, for thereby we can without hurt to ourselves gain a clear view of the best course to pursue. It is this which forces us to consider that the knowledge gained from the study of true history is the best of all educations for practical life. For it is history, and history alone, which, without involving us in actual danger, will mature our judgment and prepare us to take right views, whatever may be the crisis or the posture of affairs. [Sidenote: Xanthippus quits Carthage.] +36.+ To return to our narrative. Having obtained this complete success the Carthaginians indulged in every sign of exultation. Thanksgivings were poured out to God, and joyful congratulations interchanged among themselves. But Xanthippus, by whose means such a happy change had been brought about and such an impulse been given to the fortunes of Carthage, did not remain there long, but took ship for home again. In this he showed his wisdom and discernment. For it is the nature of extraordinary and conspicuous achievements to exasperate jealousies and envenom slander; against which a native may perhaps stand with the support of kinsfolk and friends, but a foreigner when exposed to one or the other of them is inevitably overpowered before long and put in danger. There is however another account sometimes given of the departure of Xanthippus, which I will endeavour at a more suitable opportunity to set forth.
