_Mervan II., the last caliph of the race, &c._
This Ommiade was surnamed _Alhemar_, that is to say, _The Ass_: an appellation which, in the East, is considered highly honourable, from the singular regard there entertained for that patient and indefatigable animal. Ariosto derived his touching episode of Isabella of Gallicia from the history of this prince. Mervan, being at one time in Egypt, became enamoured of a religious recluse whom he chanced to see there, and endeavoured to persuade her to break her monastic vows. Effectually to relieve herself from his persecutions, the young devotee promised him an ointment which would render him invulnerable, and volunteered to prove its efficacy on her own person. After having anointed her neck with the mixture, she requested the caliph to test the keenness of his cimeter on it, which the barbarian did; and the result may be easily imagined.
Haroun al Raschid (which signifies Haroun the Just) was { 210} greatly renowned in the East. He undoubtedly, in part, owed his fame, as well as his surname, to the protection he afforded to men of letters. His military exploits and his love of science prove this caliph to have been no ordinary man; but then the glory of his achievements was tarnished by his cruelty to the Barmacides. These were a distinguished tribe or family, descended from the ancient kings of Persia. They had rendered the most signal services to the successive caliphs, and won the respect and affection of the whole empire. Giaffar Barmacide, who was considered the most virtuous of Mussulmans and the most eminent author of the age, was the vizier of Haroun. He entertained a passionate regard for Abassa, the beautiful and accomplished sister of the caliph, and the princess reciprocated his affection; but the sovereign made the most unreasonable opposition to the celebration of their nuptials. This they effected, however, without his knowledge; and for some time Haroun remained ignorant of the union of the lovers. But, at the end of some years, the caliph made a pilgrimage to Mecca, to which city, the more effectually to secure the inviolability of his secret, the Bermacide had sent his infant son to be reared. There the representative of the Prophet, through the instrumentality of a perfidious slave, became acquainted with all the circumstances of the deception that had been practised on him. It would be difficult to believe the account of what followed, but that the facts were so well authenticated throughout Asia. Haroun caused his sister to be thrown into a well, commanded that Giaffar should lose his head, and ordered every relative of the unfortunate Bermacide to be put to death. The father of the vizier, a venerable old man, respected throughout the empire, which he had long governed, met his fate with the most heroic firmness. Before he expired, he wrote these { 211} words to the sanguinary despot: "_The accused departs first; the accuser will shortly follow. Both will appear in the presence of a Judge whom no arguments can deceive!_"
