and insufficiency of my guides. The Greeks, so loquacious in controversy, have not been anxious to celebrate the triumphs of their enemies. After a century of ignorance, the first annals of the Mussulmans were collected in a great measure from the voice of tradition. Among the numerous productions of Arabic and Persian literature, our interpreters have selected the imperfect sketches of a more recent age. The art and genius of history have ever been unknown to the Asiatics; they are ignorant of the laws of criticism; and our monkish chronicle of the same period may be compared to their most popular works, which are never vivified by the spirit of philosophy and freedom. The Oriental library of a Frenchman would instruct the most learned mufti of the East; and perhaps the Arabs might not find in a single historian so clear and comprehensive a narrative of their own exploits as that which will be deduced in the ensuing sheets.

I. In the first year of the first caliph, his lieutenant Caled, the Sword of God, and the scourge of the infidels, advanced to the banks of the Euphrates, and reduced the cities of Anbar and Hira. Westward of the ruins of Babylon, a tribe of sedentary Arabs had fixed themselves on the verge of the desert; and Hira was the seat of a race of kings who had embraced the Christian religion, and reigned above six hundred years under the shadow of the throne of Persia. The last of the Mondars * was defeated and slain by Caled; his son was sent a captive to Medina; his nobles bowed before the successor of the prophet; the people was tempted by the example and success of their countrymen; and the caliph accepted as the first-fruits of foreign conquest an annual tribute of seventy thousand pieces of gold. The conquerors, and even their historians, were astonished by the dawn of their future greatness: "In the same year," says Elmacin, "Caled fought many signal battles: an immense multitude of the infidels was slaughtered; and spoils infinite and innumerable were acquired by the victorious Moslems." But the invincible Caled was soon transferred to the Syrian war: the invasion of the Persian frontier was conducted by less active or less prudent commanders: the Saracens were repulsed with loss in the passage of the Euphrates; and, though they chastised the insolent pursuit of the Magians, their remaining forces still hovered in the desert of Babylon.

The indignation and fears of the Persians suspended for a moment their intestine divisions. By the unanimous sentence of the priests and nobles, their queen Arzema was deposed; the sixth of the transient usurpers, who had arisen and vanished in three or four years since the death of Chosroes, and the retreat of Heraclius. Her tiara was placed on the head of Yezdegerd, the grandson of Chosroes; and the same æra, which coincides with an astronomical period, has recorded the fall of the Sassanian dynasty and the religion of Zoroaster. The youth and inexperience of the prince (he was only fifteen years of age) declined a perilous encounter: the royal standard was delivered into the hands of his general Rustam; and a remnant of thirty thousand regular troops was swelled in truth, or in opinion, to one hundred and twenty thousand subjects, or allies, of the great king. The Moslems, whose numbers were reënforced from twelve to thirty thousand, had pitched their camp in the plains of Cadesia: and their line, though it consisted of fewer men, could produce more soldiers, than the unwieldy host of the infidels. I shall here observe, what I must often repeat, that the charge of the Arabs was not, like that of the Greeks and Romans, the effort of a firm and compact infantry: their military force was chiefly formed of cavalry and archers; and the engagement, which was often interrupted and often renewed by single combats and flying skirmishes, might be protracted without any decisive event to the continuance of several days. The periods of the battle of Cadesia were distinguished by their peculiar appellations. The first, from the well-timed appearance of six thousand of the Syrian brethren, was denominated the day of succor. The day of concussion might express the disorder of one, or perhaps of both, of the contending armies. The third, a nocturnal tumult, received the whimsical name of the night of barking, from the discordant clamors, which were compared to the inarticulate sounds of the fiercest animals. The morning of the succeeding day * determined the fate of Persia; and a seasonable whirlwind drove a cloud of dust against the faces of the unbelievers. The clangor of arms was reechoed to the tent of Rustam, who, far unlike the ancient hero of his name, was gently reclining in a cool and tranquil shade, amidst the baggage of his camp, and the train of mules that were laden with gold and silver. On the sound of danger he started from his couch; but his flight was overtaken by a valiant Arab, who caught him by the foot, struck off his head, hoisted it on a lance, and instantly returning to the field of battle, carried slaughter and dismay among the thickest ranks of the Persians. The Saracens confess a loss of seven thousand five hundred men; and the battle of Cadesia is justly described by the epithets of obstinate and atrocious. The standard of the monarchy was overthrown and
