GREAT many years ago there dwelt in a city of the East, of which you have never heard the name, a wise and holy man. He was highly esteemed by his fellow citizens, for he was kind and benevolent, never refusing good counsel to those in earnest to profit by it, so that by degrees the fame of his sagacity spread far and wide, and many came from great distances to consult him. One day he was sitting in front of his modest dwelling, enjoying the soft breeze that stirred the trees hard by, reading from time to time short passages of an ancient volume open upon his knees, when a shadow fell across its pages, and looking up, he perceived that a stranger stood before him, who saluted him with the greatest respect and courtesy. The sage returned the customary greetings, and then inquired in what he could be of service to the new-comer.
