from 'Arabian Nights':
...Aladdin's mother took the lamp and said to her son, "Here it is, but it is very dirty. If it were a little cleaner I believe it would bring something more."
She took some fine sand and water to clean it. But she had no sooner begun to rub it, than in an instant a hideous genie of gigantic size appeared before her, and said to her in a voice of thunder, "What wouldst thou have? I am ready to obey thee as thy slave, and the slave of all those who have that lamp in their hands; I, and the other slaves of the lamp."
Aladdin's mother, terrified at the sight of the genie, fainted; when Aladdin ... snatched the lamp out of his mother's hand, and said to the genie boldly, "I am hungry. Bring me something to eat."
