It is well known that proper names in the East, and especially among the Mohammadans, follow no such simple rule as that which has long prevailed in modern Europe, where the Christian name or names conferred in infancy and the family name or surnames are usually borne through life, and where it is a matter of suspicion to have an alias. In the East, on the other hand, we hear of persons gathering up in the course of their career a variety of names, and being popularly known by one or other of them at different periods, and to an extent that gives rise to perplexity. This was notably the case among the Arabs in the height of their preeminence. A person might receive a name in his infancy (usually conferred on his birth or at his circumcision), and to this might be added a patronymic, or a name expressive of his paternal or family relations. He might then receive a title expressive of his zeal for the faith, and soubriquets descriptive of his personal qualities or appearance, or the country or town in which he was born or had settled, or the religious sect to which he belonged ; and if he played a part in public life, to all these might be added, as in Europe, a title or titles of dignity; and if he had acquired a reputation as an author, he might assume some name of fancy. These various names or titles might never be united in the same individual, but the combinations are numerous and shifting. Certain rules are observed in their formation or application, but it was a matter of accident by which of these designations a person might be known to his contemporaries, or his name transmitted to modern times.
