Gradually, however, a change came over the victorious Arab race. The warriors lost their intense religious inspiration. They fought among themselves for place and power. The enormous wealth which they had conquered, with its resulting temptations to luxury and ease and empty vanity, weakened them, lured them from both the high moral strength which they had really attained, and from the fanatic frenzy of faith which had been their pride. They removed the capital of their empire from the holy cities of Arabia, first to Damascus and then to Bagdad, the wonderful dream-city of splendor which they built upon the banks of the ancient Tigris river. Under these gorgeous Caliphs of Bagdad, such as Haroun al Raschid of "Arabian Nights'" fame, a civilization developed which Mohammed would never have recognized as his own, which he would indeed have been the first to repudiate. Unrestrained power bred a callous indifference to the sufferings of its victims, and even a barbarous delight in inflicting torture. The tyranny of the ruling classes bred a corresponding falsity in their helpless but supple servitors. Truth, the chief virtue in Mohammed's teaching, became unknown in human intercourse, except as a poetic ideal. From their priest-king down, through all the ranks of society, men talked much of the virtues, while surrendering themselves almost wholly to the passions. One might of course speak cynically of mankind's having found this somewhat true in every age, but seldom has the tragic contrast between the ideal and the actual been brought into such sharp and visible form as in the medieval world of Bagdad. From this fertile though unhealthy soil a new literature sprang up, typical of the time and place. Here were centered the wealth and leisure and most of what survived of the culture of ancient Asia and Africa. So wit and learning journeyed there as well. At first the new literature found voice mainly as history or biography, or as a rather crude form of these collections of anecdotes purporting to give the virtues and chief events in the lives of former caliphs. Among the writers of these semi-biographic tales, by far the most noted and most noteworthy is Masoudi (died A.D. 957). His huge work, the "Golden Meadows," fills many volumes, from which we give the most attractive anecdotes. While such tales must not be taken as genuine history, they teach us very clearly the spirit of their age.
