At length Aurelian, the Roman emperor, entered the field against her; and the loss of two great battles, the former near Antioch, the latter at Emesa, reduced her to the necessity of taking shelter within the walls of her own capital. Aurelian besieged her there; but the enterprise was exceedingly difficult. “The Roman people,” said Aurelian, “speak with contempt of the war, which I am waging against a woman. They are ignorant both of the character and power of Zenobia. It is impossible to enumerate her warlike preparations, of stones, of arrows, and of every species of missile weapons. Every part of the walls is provided with two or three balistæ[59], and artificial fires are thrown from her military engines. The fear of punishment has armed her with a desperate courage. Yet I still trust to the protecting deities of Rome, who have hitherto been favourable to all my undertakings.” In another letter he writes to the senate in the following terms:—“I hear, Conscript Fathers, that it hath been urged against me, that I have not accomplished a manly task, in not triumphing over Zenobia. But my very blamers themselves would not know how to praise me enough, if they knew that woman; her firmness of purpose; the dignity she preserves towards her army; her munificence when circumstances require it; her severity, when to be severe is to be just. I may say, that the victory of Odenatus over the Persians, and his putting Sapor to flight, and his reaching Ctesiphon, were due to her. I can assert that such was the dread entertained of this woman among the nations of the East and of Egypt, that she kept in check the Arabians, the Saracens, and the Armenians; nor would I have preserved her life, if I had not thought she would much benefit the Roman state.” This was written after her defeat. Tired of making unsuccessful attempts, Aurelian determined to try the effects of negotiation, and accordingly wrote to Zenobia. The style he adopted, however, rather commanded terms than proposed them:— “_Aurelian, emperor of the Roman world, to Zenobia, and the others united together in hostile alliance._ “You ought to do that of your own accord, which is commanded by my letters. I charge you to surrender, on your lives being spared; and you, Zenobia, may pass your life in some spot where I shall place you, in pursuance of the distinguished sentence of the senate; your gems, silver, gold, silk, horses, and camels, being given up to the Roman treasury. The laws and institutions of the Palmyrenes shall be respected.” To this letter Zenobia returned the following answer:— “_Zenobia, Queen of the East, to the Roman Emperor, Aurelian._
