This story is from the collection called The Caravan, and is told by the traveller Selim.
The Caliph Chasid of Bagdad was sitting one fine summer afternoon comfortably on his divan; he had slept a little, for it was a sultry day, and he looked quite refreshed after his nap. He smoked a long rosewood pipe, sipped now and then a little coffee which a slave poured out for him, and stroked his beard contentedly whenever he had enjoyed it. In short, it could be seen at a glance that the Caliph felt very comfortable. At such a time it was easy to approach him, as he was very good-tempered and affable, wherefore his Grand Vizier Mansor visited him every day about this time. This afternoon he came as usual, looking, however, very grave, a rare thing for him. The Caliph took the pipe out of his mouth and said: ‘Why dost thou make so grave a face, Grand Vizier?’ The Grand Vizier folded his arms across his breast, bowed to his master and answered: ‘Master! whether I assume a grave appearance I know not, but down below in the palace stands a pedlar who has such fine wares that it vexes me that I have no money to spare.’
The Caliph, who had long desired to rejoice the heart of his Grand Vizier, ordered his black slave to fetch the pedlar. In a few moments the slave returned with him. He was a stout little man, swarthy in the face, and dressed in rags. He carried a box in which he had all sorts of wares, pearls, and rings, pistols with richly inlaid stocks, goblets, and combs. The Caliph and his Vizier inspected everything, and the Caliph at last bought for himself and Vizier a pair of pistols, and for the Vizier’s wife a comb. As the pedlar was about to close his box again, the Caliph caught sight of a little drawer, and asked whether it also contained some wares. The pedlar pulled out the drawer, and exhibited a snuff-box containing a black powder and a piece of paper with peculiar writing on it, which neither the Caliph nor Mansor could read. ‘These things were given to me one day by a merchant who found them in the streets of Mecca,’ said the pedlar. ‘I know not what they are; but you may have them for a small sum, for they are of no use to me.’ The Caliph, who was very fond of having old manuscripts in his library, though unable to read them, bought both paper and box and dismissed the pedlar. Still he thought he would like to know what the writing meant, and asked the Vizier if he did not know anybody who might decipher it. ‘Most gracious lord and master,’ answered the latter, ‘near the Great Mosque lives a man called Selim the learned; he knows all languages. Send for him; perhaps he can explain these mysterious signs.’
The learned Selim soon arrived. ‘Selim,’ said the Caliph to him, ‘Selim, it is said thou art very learned. Just look at this writing whether thou canst read it; if thou canst read it, thou gettest a new robe of honour from me; if thou canst not, thou gettest twelve boxes on the ears and twenty-five lashes on the soles of thy feet, for having been called Selim the learned without cause.’ Selim bowed and said: ‘Thy will be done, O Master!’ For a long time he looked at the writing; suddenly, however, he exclaimed: ‘That is Latin, O Master, or let me be hung!’ ‘Say what it means,’ demanded the Caliph, ‘if it is Latin.’
Selim began to translate: ‘Man who findeth this, praise Allah for his goodness. He who takes a pinch of this powder in this box and therewith says “Mutabor,” can change himself into any animal, and also understand the language of animals. If he afterwards wish to resume his human form, let him bow thrice to the East and say the same word. But beware when thou art changed that thou laughest not, or the magic word will depart from thy memory for ever, and thou remainest a beast.’
When Selim the learned had read this, the Caliph was pleased beyond measure. He made the learned man swear not to reveal the secret to any one, presented him with a splendid robe, and dismissed him. Then turning to his Grand Vizier he said: ‘This I call making a bargain, Mansor! How glad I am at being able to become an animal! Come to me to-morrow morning. We will then go together into the fields, take a pinch out of the box, and then listen to what is said in the air and the water, in wood and field.’
Next morning, scarcely had the Caliph Chasid breakfasted and dressed himself, when the Grand Vizier appeared as ordered, to accompany him on his walk. The Caliph put the box with the magic powder in his girdle, and having ordered his suite to remain behind, he and the Grand Vizier set out alone on the journey. They first passed through the large gardens of the Caliph, but looked in vain for any living thing on which to try the experiment. The Vizier at last proposed to pursue their journey to a pond, where he had often seen many animals, especially storks, whose grave manners and clappings had always excited his attention.
The Caliph approved of the Vizier’s proposal, and went with him towards the pond. Having arrived there, they saw a stork soberly pacing up and down looking for frogs, and chattering something now and then to itself. At the same moment they saw far up in the sky another stork hovering in this direction.
‘I wager my beard, most gracious Master,’ said the Grand Vizier, ‘this long-legged pair are now having a pleasant talk. How would it be if we turned into storks?’
