In the beginning of the 15th century, there lived at Bagdad an aged merchant who had grown wealthy in his business, and who had an only son to whom he was tenderly attached. He resolved to marry him to the daughter of another merchant, a girl of considerable fortune, but without any personal attractions. Abul-Hassan, the merchant’s son, on being shown the portrait of the lady, requested his father to delay the marriage till he could reconcile his mind to it. Instead, however, of doing this, he fell in love with another girl, the daughter of a sage, and he gave his father no peace till he consented to the marriage with the object of his affections. The old man stood out as long as he could, but finding that his son was bent on acquiring the hand of the fair Nadilla, and was equally resolute not to accept the rich and ugly lady, he did what most fathers, under such circumstances, are constrained to do, he acquiesced. The wedding took place with great pomp and ceremony, and a happy honeymoon ensued, which might have been happier but for one little circumstance which led to very serious consequences. Abul-Hassan noticed that his bride quitted the nuptial couch as soon as she thought her husband was asleep, and did not return to it, till an boar before dawn. Filled with curiosity, Hassan one night feigned sleep, and saw his wife rise and leave the room as usual. He followed cautiously, and saw her enter a cemetery. By the straggling moonbeams he beheld her go into a tomb; he stepped in after her. The scene within was horrible. A party of ghouls were assembled with the spoils of the graves they had violated., and were feasting on the flesh of the long-buried corpses. His own wife, who, by the way, never touched supper at home, played no inconsiderable part in the hideous banquet. As soon as he could safely escape, Abul-Hassan stole back to his bed. He said nothing to his bride till next evening when supper was laid, and she declined to eat; then he insisted on her partaking, and when she positively refused, he exclaimed wrathfully,—“Yes, you keep your appetite for your feast with the ghouls!” Nadilla was silent; she turned pale and trembled, and without a word sought her bed. At midnight she rose, fell on her husband with her nails and teeth, tore his throat, and having opened a vein, attempted to suck his blood; but Abul-Hassan springing to his feet threw her down, and with a blow killed her. She was buried next day. Three days after, at midnight, she re-appeared, attacked her husband again, and again attempted to suck his blood. He fled from her, and on the morrow opened her tomb, burned her to ashes, and cast them into the Tigris. This story connects the ghoul with the vampire. As will be seen by a former chapter, the were-wolf and the vampire are closely related.
