The grand vizier endeavoured to divert the sultan from this design; he represented to him the danger to which he might be exposed, and that all his labour might perhaps be in vain; but it was to no purpose; the sultan was resolved. He put on a suit fit for walking and took his cimeter; and as soon as he found that all was quiet in the camp, went out alone, and passed over one of the hills without much difficulty; he found the descent still more easy, and when he came to the plain, walked on till the sun arose, and then he saw before him, at a considerable distance, a vast building. He rejoiced at the sight, in hopes of receiving there the information he sought. When he drew near, he found it was a magnificent palace, or rather a strong castle, of black polished marble, and covered with fine steel, as smooth as glass. Being highly pleased that he had so speedily met with something worthy his curiosity, he stopped before the front of the castle, and considered it with attention.
