luxury and science; but, in a reign of three-and-twenty years, Harun repeatedly visited his provinces from Chorasan to Egypt; nine times he performed the pilgrimage of Mecca; eight times he invaded the territories of the Romans; and as often as they declined the payment of the tribute, they were taught to feel that a month of depredation was more costly than a year of submission. But when the unnatural mother of Constantine was deposed and banished, her successor, Nicephorus, resolved to obliterate this badge of servitude and disgrace. The epistle of the emperor to the caliph was pointed with an allusion to the game of chess, which had already spread from Persia to Greece. "The queen (he spoke of Irene) considered you as a rook, and herself as a pawn. That pusillanimous female submitted to pay a tribute, the double of which she ought to have exacted from the Barbarians. Restore therefore the fruits of your injustice, or abide the determination of the sword." At these words the ambassadors cast a bundle of swords before the foot of the throne. The caliph smiled at the menace, and drawing his cimeter, _samsamah_, a weapon of historic or fabulous renown, he cut asunder the feeble arms of the Greeks, without turning the edge, or endangering the temper, of his blade. He then dictated an epistle of tremendous brevity: "In the name of the most merciful God, Harun al Rashid, commander of the faithful, to Nicephorus, the Roman dog. I have read thy letter, O thou son of an unbelieving mother. Thou shalt not hear, thou shalt behold, my reply." It was written in characters of blood and fire on the plains of Phrygia; and the warlike celerity of the Arabs could only be checked by the arts of deceit and the show of repentance. The triumphant caliph retired, after the fatigues of the campaign, to his favorite palace of Racca on the Euphrates: but the distance of five hundred miles, and the inclemency of the season, encouraged his adversary to violate the peace. Nicephorus was astonished by the bold and rapid march of the commander of the faithful, who repassed, in the depth of winter, the snows of Mount Taurus: his stratagems of policy and war were exhausted; and the perfidious Greek escaped with three wounds from a field of battle overspread with forty thousand of his subjects. Yet the emperor was ashamed of submission, and the caliph was resolved on victory. One hundred and thirty-five thousand regular soldiers received pay, and were inscribed in the military roll; and above three hundred thousand persons of every denomination marched under the black standard of the Abbassides. They swept the surface of Asia Minor far beyond Tyana and Ancyra, and invested the Pontic Heraclea, once a flourishing state, now a paltry town; at that time capable of sustaining, in her antique walls, a month's siege against the forces of the East. The ruin was complete, the spoil was ample; but if Harun had been conversant with Grecian
