The Persian army is next day seen by Fausta and Piso, from the towers, whence the eye commanded the whole plain, to be approaching to the relief of Zenobia. They encounter the Roman army, and terrible slaughter ensues; while, at a signal from the Queen, who with half the population of Palmyra are on the walls, Zabdas, at the head of all the flower of the Palmyra cavalry, pours forth from the gates, followed closely by the infantry, the battle meanwhile raging fiercely between the walls and the Roman entrenchments, as well as beyond. But the Palmyrenes are repulsed with great slaughter; the routed army press back into the city, and the gates are closed upon the pursuers. In the evening, at the house of Gracchus, where the events of the day are discussed, Calpurnius, who had been in the thickest of the fight, but had escaped unhurt, relates the fate of Zabdas. The scene is one for the pencil: "Calpurnius had been in the thickest of the fight, but had escaped unhurt. He was near Zabdas when he fell, and revenged his death by hewing down the soldier who had pierced him with his lance. "'Zabdas,' said Calpurnius, when in the evening we recalled the sad events of the day, 'was not instantly killed by the thrust of the spear, but falling backward from his horse, found strength and life enough remaining to raise himself upon his knee, and cheer me on, as I flew to revenge his death upon the retreating Roman. As I returned to him, having completed my task, he had sunk upon the ground, but was still living, and his eye bright with its wonted fire. I raised him in my arms, and lifting him upon my horse, moved toward the gate, intending to bring him within the walls. But he presently entreated me to desist. "'I die,' said he, 'it is all in vain, noble Piso. Lay me at the root of this tree, and that shall be my bed, and its shaft my monument.' "I took him from the horse as he desired. "'Place me,' said he, 'with my back against the tree, and my face toward the entrenchments, that while I live I may see the battle--Piso, tell the Queen that to the last hour I am true to her. It has been my glory in life to live but for her, and my death is a happiness, dying for her. Her image swims before me now, and over her hovers a winged victory. The Romans fly--I knew it would be so--the dogs cannot stand before the cavalry of Palmyra--they never could--they fled at Antioch. Hark! there are the shouts of triumph--bring me my horse--Zenobia! live and reign for ever!' "'With these words his head fell upon his bosom, and he died. I returned to the conflict; but it had become a rout, and I was borne along with the rushing throng toward the gates.'"
