The emperor embraced the more generous resolution of defending, in a siege and battle, the country of his ancestors. When the armies drew near, the front of the Mahometan line appeared to a Roman eye more closely planted with spears and javelins; but the event of the action was not glorious on either side to the national troops. The Arabs were broken, but it was by the swords of thirty thousand Persians, who had obtained service and settlement in the Byzantine empire. The Greeks were repulsed and vanquished, but it was by the arrows of the Turkish cavalry; and had not their bowstrings been damped and relaxed by the evening rain, very few of the Christians could have escaped with the emperor from the field of battle. They breathed at DorylÊum, at the distance of three days; and Theophilus, reviewing his trembling squadrons, forgave the common flight both of the prince and people. After this discovery of his weakness, he vainly hoped to deprecate the fate of Amorium: the inexorable caliph rejected with contempt his prayers and promises; and detained the Roman ambassadors to be the witnesses of his great revenge. They had nearly been the witnesses of his shame. The vigorous assaults of fifty-five days were encountered by a faithful governor, a veteran garrison, and a desperate people; and the Saracens must have raised the siege, if a domestic traitor had not pointed to the weakest part of the wall, a place which was decorated with the statues of a lion and a bull. The vow of Motassem was accomplished with unrelenting rigor: tired, rather than satiated, with destruction, he returned to his new palace of Samara, in the neighborhood of Bagdad, while the _unfortunate_ Theophilus implored the tardy and doubtful aid of his Western rival the emperor of the Franks. Yet in the siege of Amorium about seventy thousand Moslems had perished: their loss had been revenged by the slaughter of thirty thousand Christians, and the sufferings of an equal number of captives, who were treated as the most atrocious criminals. Mutual necessity could sometimes extort the exchange or ransom of prisoners: but in the national and religious conflict of the two empires, peace was without confidence, and war without mercy. Quarter was seldom given in the field; those who escaped the edge of the sword were condemned to hopeless servitude, or exquisite torture; and a Catholic emperor relates, with visible satisfaction, the execution of the Saracens of Crete, who were flayed alive, or plunged into caldrons of boiling oil. To a point of honor Motassem had sacrificed a flourishing city, two hundred thousand lives, and the property of millions. The same caliph descended from his horse, and dirtied his robe, to relieve the distress of a decrepit old man, who, with his laden ass, had tumbled into a ditch. On which of these actions did he reflect with the most pleasure, when he was summoned by the angel of death?
