Concerning this last, European writers add, that whenever he mounted his horse, he placed his foot on the neck of the Ottoman sultan, as, it is said, the Persian king, Shabur (Sapor), had done a thousand years before, to his captive, the Roman emperor, Valerian. Valerian and Bajazet perished in the captivity of Shabur and Timur; but Sandjar had the good fortune to make his escape from his barbarous conquerors, and returned to Khorassan, where he died the following year, from melancholy, caused by his bad fortune, and the desolation of his states; after a reign of fifty-one years, and a life of nearly a hundred, as he had before he became sole ruler, acted, for twenty-one years, as viceroy of his brothers, in Khorassan. His brilliant exploits, and the encomiums of the poets, have caused his name to shine among those of the most illustrious princes of the east; and have not undeservedly gained him the surname of Alexander the Second. The greatest poets of his time, Selmar and Ferideddin Katib, sang his praise; but, above all, Enweri, the Persian Pindar. Unequalled in his panegyrics, either by his predecessor, Khakani, or his follower, Farjabi, who, with him, form the astral triangle of Persian panegyrists, he raised the name of Sandjar high above the regions of earth in the light of the milky way, and to the highest heavens, in the midst of the music of the spheres. While Enweri thus bestowed immortality on Sandjar in his works, the poet Sabir did him a no less essential service in prolonging his sublunary existence, by protecting him from the murderous dagger. When Itsis, the governor of Khowaresm, rebelled against Sandjar, the latter sent the poet, one of the most faithful and respected in his court, secretly to Khorassan, as a spy upon the designs of the rebellious governor. He succeeded in ascertaining that Itsis had engaged an Assassin (Fedavi), to murder the sultan, in the mosque, on a Friday. The murderer was discovered, by means of the exact description sent by Sabir to Sandjar, and, after confessing every thing, he was put to death. Itsis, however, who was aware that Sabir had caused his design to fail, had him drowned in the Oxus.[138] Sabir thus gained an immortal name, in the ranks of great poets and faithful servants, not only by his encomiastic poems, but also by his praiseworthy deeds. Sandjar, who, at first, had been favourably inclined towards the Assassins, seems to have had his eyes opened by this attempt, and to have been urged to the severity with which, as we have already related, in his latter years, he pursued the order who had caused the irruption of the Turcomans.
