There was once upon a time a man whom other men called Aben Hassen the Wise. He had read a thousand books of magic, and knew all that the ancients or moderns had to tell of the hidden arts.
The King of the Demons of the Earth, a great and hideous monster, named Zadok, was his servant, and came and went as Aben Hassen the Wise ordered, and did as he bade. After Aben Hassen learned all that it was possible for man to know, he said to himself, "Now I will take my ease and enjoy my life." So he called the Demon Zadok to him, and said to the monster, "I have read in my books that there is a treasure that was one time hidden by the ancient kings of Egypt--a treasure such as the eyes of man never saw before or since their day. Is that true?"
"It is true," said the Demon.
"Then I command thee to take me to that treasure and to show it to me," said Aben Hassen the Wise.
"It shall be done," said the Demon; and thereupon he caught up the Wise Man and transported him across mountain and valley, across land and sea, until he brought him to a country known as the "Land of the Black Isles," where the treasure of the ancient kings was hidden. The Demon showed the Magician the treasure, and it was a sight such as man had never looked upon before or since the days that the dark, ancient ones hid it. With his treasure Aben Hassen built himself palaces and gardens and paradises such as the world never saw before. He lived like an emperor, and the fame of his doings rang through all the four corners of the earth.
