The Arabian tribes were confounded by the Greeks and Romans under the indiscriminate appellation of Saracens; a name whose etymology has been variously, but never satisfactorily, explained. This was their general name when Mohammed appeared in the beginning of the seventh century. Their religion at this time was Sabianism, or the worship of the sun, moon, &c; variously transformed by the different tribes, and intermingled with some Jewish and Christian maxims and traditions. The tribes themselves were generally at variance, from some hereditary and implacable animosities; and their only warfare consisted in desultory skirmishes arising out of these feuds, and in their predatory excursions, where superiority of numbers rendered courage of less value than activity and vigilance. Yet of such materials Mohammed constructed a mighty empire; converted the relapsed Ishmaelites into good Musselmen; united the jarring tribes under one banner; supplied what was wanting in personal courage by the ardour of religious zeal; and out of a banditti, little known and little feared beyond their own deserts, raised an armed multitude, which proved the scourge of the world. Mohammed was born in the year 569, of the noble tribe of the Koreish, and descended, according to eastern historians, in a direct line from Ishmael. His person is represented as beautiful, his manners engaging, and his eloquence powerful; but he was illiterate, like the rest of his countrymen, and indebted to a Jewish or Christian scribe for penning his Koran. Whatever the views of Mohammed might have been in the earlier part of his life, it was not till the fortieth year of his age that he avowed his mission as the Apostle of God: when so little credit did he gain for his pretensions, that in the first three years he could only number fourteen converts; and even at the end of ten years his labours and his friends were alike confined within the walls of Mecca, when the designs of his enemies compelled him to fly to Medina, where he was favourably received by a party of the most considerable inhabitants, who had recently imbibed his doctrines at Mecca. This flight, or _Hegira_, was made the Mohammedan æra, from which time is computed, and corresponds with the 16th of July, 622, of the Christian æra. Mohammed now found himself sufficiently powerful to throw aside all reserve; declared that he was commanded to compel unbelievers by the sword to receive the faith of one God, and his prophet Mohammed; and confirming his credulous followers by the threats of eternal pain on the one hand, and the allurements of a sensual paradise on the other, he had, before his death, which happened in the year 632, gained over the whole of Arabia to his imposture. His death threw a temporary gloom over his cause, and the disunion of his followers threatened its extinction. Any other empire placed in the same circumstances would have crumbled to pieces; but the Arabs felt their power; they revered their founder as
