The nucleus, around which aggregated those countless multitudes, was a small band of valiant warriors who unfurled in their native deserts the standard of a new creed. They were not, before Mohammed's time, a new or unknown people. They had frequently come in contact with the Jews and Phenicians, and had in their veins the blood of both these nations. Taking advantage of their favorable situation for commerce, they had performed the carrier trade of the Red Sea, and the eastern coast of Africa and India, for the most celebrated nations of ancient times, the Jews and the Phenicians, later still, for the Romans and Persians. They had the same traditions in common with the Shemitic and Hamitic families from which they sprung.[183] They had even taken an active part in the political life of neighboring nations. Under the Arsacides and the sons of Sassan, some of their tribes exerted great influence in the politics of the Persian empire. One of their adventurers[184] had become Emperor of Rome; one of their princes protected the majesty of Rome against a conqueror before whom the whole east trembled, and shared the imperial purple with the Roman sovereign;[185] one of their cities had become, under Zenobia, the centre and capital of a vast empire that rivalled and even threatened Rome.[186] It is evident, therefore, that the Arab nation had never ceased, from the remotest antiquity, to entertain intimate relations with the most powerful and celebrated ancient societies. It had taken part in their political and intellectual[187] activity; and it might not inappropriately be compared to a body half-plunged into the water, and half exposed to the sun, as it partook at the same time of an advanced state of civilization and of complete barbarism. Mohammed invented the religion most conformable to the ideas of a people, among whom idolatry had still many zealous adherents, but where Christianity, though having made numerous converts, was losing favor on account of the endless schisms and contentions of its followers.[188] The religious dogma of the Koreishite prophet was a skilful compromise between the various contending opinions. It reconciled the Jewish dispensation with the New Law better than could the Church at that time, and thus solved a problem which had disquieted the consciences of many of the earlier Christians, and which, especially in the east, had given rise to many heretical sects. This was in itself a very tempting bait, and, besides, any theological novelty had decided chances of success among the Syrians and Egyptians.[189] Moreover, the new religion appeared with sword in hand, which in those times of schismatical propagandism seemed a warrant of success more relied upon by the masses to whom it addressed itself, than peaceful persuasion.
