discerning in what way the different animals were made to vanish into the air, in the mysterious manner above described. This, I may venture to affirm, was beyond measure strange and surprising.” Ibn Batuta (the celebrated traveller, who has been called the Mahometan Marco Polo of the fourteenth century), to whom a reference has already been made, narrates delusions of the same kind, of which he was an eye-witness. He informs us that, when he was once in the presence of the Emperor of Hindustan, two Yogees came in, whom the monarch desired to show him what he had never yet seen. They said, “‘We will.’ One of them then assumed the form of a cube, and arose from the earth, and, in this cubic shape, he occupied a place in the air over our heads. I was so much astonished and terrified at this, that I fainted and fell to the earth. The emperor then ordered me some medicine which he had with him, and, upon taking this, I recovered and sat up; this cubic figure still remaining in the air just as it had been. His companion then took a sandal, belonging to one of those who had come out with him, and struck it upon the ground as if he had been angry. The sandal then ascended until it became opposite in situation with the cube. It then struck it upon the neck, and the cube gradually descended to the earth, and at last rested in the place it had left. The emperor then told me that the man who took the form of a cube was a disciple to the owner of the sandal. ‘And,’ continued he, ‘had I not entertained fears for the safety of thy intellect, I should have ordered him to show thee greater things than these.’ From this, however, I took a palpitation of the heart, until the emperor ordered me a medicine, which restored me.”
