62. The Romans, not departing from the bank of the Peneüs, transferred their camp to a safer place. [2] There Misagenes the Numidian arrived with a thousand cavalry, an equal number of infantry, and in addition twenty-two elephants. [3] As during these days the king was holding a council concerning his general policy, now that his overboldness resulting from success had subsided, some of his friends took courage to advise him to use his good fortune as a basis for an honourable peace rather than, led astray by idle hope, to throw himself into irrevocable disaster. To impose restraint on success and not to trust too much to the calm of his present fortune, they said, was the way of a wise man and one who was deservedly fortunate. [4] Let him send to the consul men to renew the treaty on the same terms as those on which his father Philip had received peace from the victorious Titus Quinctius.¹ [5] The war could not be ended more gloriously than with so memorable a fight, nor could a [6??] more well-founded hope of lasting peace present itself than that which would make the Romans, shaken by the loss of a battle, more moderate in framing the treaty. But [p. 485]if then too the innate stubbornness of the Roman² should scorn fair terms, gods and men would be witnesses both of Perseus' moderation and of his opponents' stiff-necked haughtiness. [7] The king's mind was never averse to such counsels. [8] And so as the opinion was approved by the assent of the majority, envoys were sent to the consul; they were heard in the presence of a full council. They asked for peace, promising that Perseus would pay the Romans as much tribute³ as [9??] Philip had promised, and that he would yield with all speed the cities, land and places which Philip had yielded. [10] So far the envoys. When after the withdrawal of the envoys the matter was discussed, Roman steadfastness⁴ carried the day in the council. [11] The custom of that age was to wear in misfortune the aspect of success and to be of temperate disposition in successes. It was decided to reply that peace would be granted on condition that the king should give to the senate the unconditional right of deciding on a general policy concerning the king himself and concerning all Macedonia.⁵ [12] When the envoys reported these terms, to those ignorant of the Roman character their obstinacy was portentous, and many advised against any further reference to peace; [13] for soon, they said, the Romans would of their own accord seek what they scorned when offered. [14] Perseus [p. 487]feared this very haughtiness —thinking that it⁶ sprang from confidence in their strength-and, increasing the sum of money, if perchance he might buy peace for a price, he did not cease to test the purpose of the consul. [15] After the latter would make no change in the terms of his first answer, Perseus, giving up hope of peace, returned to Sycurium from whence he had set out, intending to try anew the fortunes of war.
