of the Christians themselves. That venerable Arab, one of the last of the companions of Mahomet, was numbered among the ansars, or auxiliaries, of Medina, who sheltered the head of the flying prophet. In his youth he fought, at Beder and Ohud, under the holy standard: in his mature age he was the friend and follower of Ali; and the last remnant of his strength and life was consumed in a distant and dangerous war against the enemies of the Koran. His memory was revered; but the place of his burial was neglected and unknown, during a period of seven hundred and eighty years, till the conquest of Constantinople by Mahomet the Second. A seasonable vision (for such are the manufacture of every religion) revealed the holy spot at the foot of the walls and the bottom of the harbor; and the mosch of Ayub has been deservedly chosen for the simple and martial inauguration of the Turkish sultans.

The event of the siege revived, both in the East and West, the reputation of the Roman arms, and cast a momentary shade over the glories of the Saracens. The Greek ambassador was favorably received at Damascus, a general council of the emirs or Koreish: a peace, or truce, of thirty years was ratified between the two empires; and the stipulation of an annual tribute, fifty horses of a noble breed, fifty slaves, and three thousand pieces of gold, degraded the majesty of the commander of the faithful. The aged caliph was desirous of possessing his dominions, and ending his days in tranquillity and repose: while the Moors and Indians trembled at his name, his palace and city of Damascus was insulted by the Mardaites, or Maronites, of Mount Libanus, the firmest barrier of the empire, till they were disarmed and transplanted by the suspicious policy of the Greeks. After the revolt of Arabia and Persia, the house of Ommiyah was reduced to the kingdoms of Syria and Egypt: their distress and fear enforced their compliance with the pressing demands of the Christians; and the tribute was increased to a slave, a horse, and a thousand pieces of gold, for each of the three hundred and sixty-five days of the solar year. But as soon as the empire was again united by the arms and policy of Abdalmalek, he disclaimed a badge of servitude not less injurious to his conscience than to his pride; he discontinued the payment of the tribute; and the resentment of the Greeks was disabled from action by the mad tyranny of the second Justinian, the just rebellion of his subjects, and the frequent change of his antagonists and successors. Till the reign of Abdalmalek, the Saracens had been content with the free possession of the Persian and Roman treasures, in the coins of Chosroes and Cæsar. By the command of that caliph, a national mint was established, both for silver and gold, and the inscription of the Dinar, though it might be censured by some timorous casuists, proclaimed the unity of the God of Mahomet. Under the reign of the caliph Walid, the Greek language and characters were excluded from the accounts of the public revenue. If this change was productive of the invention or familiar use of our present numerals, the Arabic or Indian ciphers, as they are commonly styled, a regulation of office has promoted the most important discoveries of arithmetic, algebra, and the mathematical sciences.

Whilst the caliph Walid sat idle on the throne of Damascus, whilst his lieutenants achieved the conquest of Transoxiana and Spain, a third army of Saracens overspread the provinces of Asia Minor, and approached the borders of the Byzantine capital. But the attempt and disgrace of the second siege was reserved for his brother Soliman, whose ambition appears to have been quickened by a more active and martial spirit. In the revolutions of the Greek empire, after the tyrant Justinian had been punished and avenged, an humble secretary, Anastasius or Artemius, was promoted by chance or merit to the vacant purple. He was alarmed by the sound of war; and his ambassador returned from Damascus with the tremendous news, that the Saracens were preparing an armament by sea and land, such as would transcend the experience of the past, or the belief of the present age. The precautions of Anastasius were not unworthy of his station, or of the impending danger. He issued a peremptory mandate, that all persons who were not provided with the means of subsistence for a three years' siege should evacuate the city: the public granaries and arsenals were abundantly replenished; the walls were restored and strengthened; and the engines for casting stones, or darts, or fire, were stationed along the ramparts, or in the brigantines of war, of which an additional number was hastily constructed. To prevent is safer, as well as more honorable, than to repel, an attack; and a design was meditated, above the usual spirit of the Greeks, of burning the naval stores of the enemy, the cypress timber that had been hewn in Mount Libanus, and was piled along the sea-shore of Phnicia, for the service of the Egyptian fleet. This generous enterprise was defeated by the cowardice or treachery of the troops, who, in the new language of the empire, were styled of the Obsequian Theme. They murdered their chief, deserted their standard in the Isle of Rhodes,
