The adoration of the Arabians consisted chiefly in the worship of the heavenly luminaries; but they had a great variety of deities, these being personifications of certain powers in nature, or passions in mankind. They were represented by idols of every variety of shape, which were gathered around the ancient temple of Caaba, at Mecca, a large square edifice, considered as the central point of religion, and the favorite seat of divinity. Their worship was attended with the most horrid rites and shocking ceremonies: even children were sacrificed to the idols, and one of the tribes was accustomed to bury their daughters alive. Except that they fancied the souls of the departed to be transformed into owls, hovering in gloom around the grave, it does not appear that they had the least idea of a future state of existence. Such was the state of religion among the native Arabians. Among the foreign settlers in the towns there were a few followers of the Greek and Roman philosophy; the Christians were never numerous. These latter were divided into a variety of sects, and those belonging to the Greek church, advocated monasteries, and were addicted to the worship of images, martyrs and relics. Some of these, even elevated the Virgin Mary into a deity, and addressed her as the third person in the Trinity. Mohammed, while he no doubt looked with horror upon this state of things, having studied the Bible, and clearly comprehended its sublime revelation of one God, conceived the idea of uniting the people of his native land under a religion of which this fundamental principle should constitute the basis. His purpose was to crush idolatry, and restore the lost worship of the true God. How far he was sincere, and how far he was an impostor, we cannot venture to affirm. It is probable that he was a religious enthusiast, deceived by his own fancies, and, perhaps, really believing his own visions. At the outset of his career, it is likely that he acted in good faith, while he was himself deluded. When he had advanced so far as to see power and dominion offered to his grasp, it is probable that his integrity gave way, and that thenceforward we are to consider him as under the alternate guidance of craft and fanaticism. Several of the nobles citizens of Mecca were finally converted by Mohammed. Khadijah was now dead, and the prophet had married Ayesha, the daughter of Abubeker, a man of great influence, and who exercised it in favor of his son-in-law. Yet the new faith made little progress, and a persecution of its votaries arose, which drove them to Abyssinia, and caused Mohammed himself to fly for safety to Medina. This flight is called the Hegira, and, taking place in the year 622, is the epoch from which Mohammedan chronology is computed, as is ours from the birth of Christ.
