In the fifth year of the caliph Omar, only seventeen years from the Prophet’s flight from Mecca, the conquest of Syria was completed.  The Christians were forbidden to build churches, or speak openly of their religion, or sit in the presence of a Mohammedan, or to sell wine, or bear arms, or use the saddle in riding, or have a domestic who had been in the Mohammedan service.  The utter prostration of all civil and religious liberty took place in the old scenes of Christian triumph.  This was an instance in which persecution proved successful; and because it was successful it is a proof, in the eyes of Carlyle, that the persecuting religion was the better, because it was outwardly the stronger.

The conquest of Egypt rapidly followed that of Syria; and with the fall of Alexandria perished the largest library of the world, the thesaurus of all the intellectual treasures of antiquity.

Then followed the conquest of Persia.  A single battle, as in the time of Alexander, decided its fate.  The marvel is that the people should have changed their religion; but then, it was Mohammedanism or death.  And a still greater marvel it is,—­an utter mystery to me,—­why that Oriental country should have continued faithful to the new religion.  It must have had some elements of vitality almost worth fighting for, and which we do not comprehend.

Nor did Saracenic conquests end until the Arabs of the desert had penetrated southward into India farther than had Alexander the Great, and westward until they had subdued the northern kingdoms of Africa, and carried their arms to the Pillars of Hercules; yea, to the cities of the Goths in Spain, and were only finally arrested in Europe by the heroism of Charles Martel.

Such were the rapid conquests of the Saracens—­and permanent conquests also—­in Asia and Africa, under the stimulus of religious fanaticism, until they had reduced thirty-six thousand cities, towns, and castles, and built fourteen thousand mosques.

Now what are the deductions to be logically drawn from these stupendous victories and the consolidation of the various religions of the conquered into the creed of Mohammed,—­not repudiated when the pressure was removed, but apparently cherished by one hundred and eighty millions of people for more than a thousand years?

We must take the ground that the religion of Mohammed has marvellous and powerful truths, which we have overlooked and do not understand, which appeal to the heart and conscience, and excite a great enthusiasm,—­so great as to stimulate successive generations with an almost unexampled ardor, and to defend which they were ready to die; a religion which has bound diverse nations together for nearly fourteen hundred years.  If so, it cannot be abused, or ridiculed, or sneered at, any more than can the dominion of the popes in the Middle Ages, but remains august in impressive mystery to us, and even to future ages.
