"As Ahmed did not return to his house, Sittâra only heard of his elevation from common rumour. She saw with despair that her wishes for his advancement had been more than accomplished, but that all her own desires had been entirely frustrated. Her husband was chief astrologer--the very situation she had set her heart on; he was rich enough to enable his wife to surpass all the ladies of Isfahan, in the number of her slaves, and the finery of her clothes and jewels, whenever she went to the Hemmâm: but he had married a princess; and his former wife, according to custom, was banished from his house, and condemned to live on whatever pittance she might receive from a man whose love and esteem she had for ever forfeited. These thoughts distracted her mind: her envy was excited by the accounts she daily heard of Ahmed's happiness, and of the beauty of the princess; and she now became anxious only for his destruction, looking on him as the sole cause of her disappointment. "An opportunity of indulging her revengeful feelings was not long wanting. The king of Seestan had sent an emerald of extraordinary size and brilliancy as a present to the king of Irak. It was carefully enclosed in a box, to which there were three keys, and one of them was given in charge to each of the three confidential servants employed to convey it. When they reached Isfahan, the box was opened, but the emerald was gone. Nothing could exceed their consternation; each accused the other: as the lock was not broken, it was evident one of them must be the thief. They consulted what was to be done; to conceal what had happened was impossible; the very attempt would have brought death on them all. It was resolved, therefore, to lay the whole matter before the king, and beg that by his great wisdom he would detect the culprit, and that he would show mercy to the other two. "The king heard the story with astonishment, but was unable to find any clue by which he might ascertain the truth. He summoned his vizier and all the wisest men of his court; but they were as much at a loss as their master. The report spread through the city; and Sittâra thought she had now the means of working her husband's ruin. She solicited a private audience of his majesty, on the plea of having a communication of importance to make. Her request was granted. On entering the royal presence she threw herself at his feet, exclaiming, 'Pardon, O king! my having so long concealed the guilt of my husband Ahmed, whose alliance is a disgrace to the royal blood. He is no astrologer, but an associate of thieves, and by that means alone did he discover the royal treasure. If any doubts are entertained of my speaking the truth, let his majesty command Ahmed to recover the emerald which the servants of the king of Seestan have stolen. Surely the man who by his wonderful art ascertained where all the treasure of the kingdom was concealed, will find it an easy matter to discover a single precious stone.'
