13. When it was announced that Syphax was being brought into the camp¹ all the rank and file poured out, as though they were to witness a triumph. [2] First came Syphax himself in chains, followed by a company of noble Numidians. Then all the soldiers in enlarging upon their own victory did their best to magnify Syphax and the [3??] fame of his race, saying [p. 413]that he was the king to whose majesty the two most² powerful peoples in the world, the Roman and the Carthaginian, paid such honour that Scipio, their own general, left his province of Spain and his army and with two quinqueremes sailed to Africa to court his friendship,³ [4??] [5??] while Hasdrubal, a general of the Carthaginians, not only came himself to him in his kingdom but also gave him his daughter in marriage. [6] They said that he had at the same time had two generals,⁴ a Carthaginian and a Roman, in his power; that just as both sides had sought the favour of the immortal gods by offering sacrifices, so had his friendship been sought at the same time by both sides. [7] Moreover, so great, they said, had been his power that when Masinissa had been driven out of his kingdom, Syphax brought him so low that his life was protected only by the report of his death and by hiding-places where he lived in the forest like wild animals on what they caught.⁵

[8] Honoured by such utterances of the bystanders the king was brought before Scipio at headquarters. Even Scipio was moved by the comparison of the man's former estate with his present condition, but especially by the memory of their guest-friendship and the clasp of hands, and of the compact made for the state and of that made in his own name. [9] The same considerations gave Syphax also spirit in addressing the victor. For when Scipio repeatedly asked him what he had meant by not only rejecting a Roman alliance but also taking the aggressive in war, he would admit that he had indeed done wrong and lost his reason, but not then for the first time when he had taken up arms against the Roman people. [10] That had been the culmination, not the beginning, [p. 415]of his madness. [11] The time when he lost his reason,⁶ when he put out of his head all private guest-friendships and public treaties, was when he admitted a noble Carthaginian lady to his house. [12] From those nuptial torches his palace had taken fire; that baneful fury by all her blandishments had unbalanced and unhinged his mind, and she had never rested until with her own hands she had herself put on him guilt-stained arms against a guest-friend and a personal friend. [13] Yet for himself, ruined and crushed, there was this consolation in his misfortunes, to see that the same baneful fury had passed into the house and home of the greatest enemy he had in the world. [14] Masinissa was neither wiser, he said, nor more steadfast than Syphax; he was even more imprudent owing to his youth. Certainly there had been -more folly and lack of self-control in Masinissa's marriage to her than in his own.⁷
