The Indian rope trick is a magic trick said to have been performed in and around India during the 19th century. Sometimes described as "the world’s greatest illusion", it reputedly involved a magician, a length of rope, and one or more boy assistants.
In the 1990s the trick was said by some historians to be a hoax perpetrated in 1890 by John Wilkie of the Chicago Tribune newspaper.Peter Lamont has argued that there are no accurate references to the trick predating 1890, and later stage magic performances of the trick were inspired by Wilkie's account.
There are old accounts from the 9th century (by Adi Shankara), the 14th century (by Ibn Battuta), and the 17th century (by the Mughal Emperor Jahangir), of versions of the trick, but this is denied by Lamont as the accounts described are different from the "classic" Indian rope trick. See explanation below.
There are three variants of the trick, which differ in the degree of theatricality displayed by the magician and his helper:
Robert Elliot of the London Magic Circle, when offering a substantial reward in the 1930s for an outdoor performance, found it necessary to define the trick. He demanded that "the rope must be thrown into the air and defy the force of gravity, while someone climbs it and disappears."
In his commentary on Gaudapada's explanation of the Mandukya Upanishad, the 9th-century Hindu teacher Adi Shankara, illustrating a philosophical point, wrote of a juggler who throws a thread up into the sky; he climbs up it carrying arms and goes out of sight; he engages in a battle in which he is cut into pieces, which fall down; finally he arises again. A few words further on Shankara referred to the principle underlying the trick, saying that the juggler who ascends is different from the real juggler who stands unseen, "veiled magically", on the ground. In Shankara's commentary on the Vedanta Sutra (also called the Brahma Sutra) he mentioned that the juggler who climbs up the rope to the sky is illusory, and so is only fancied to be different from the real juggler, who is hidden on the ground. The fact that Shankara referred to the trick's method was pointed out in 1934 in a discussion of the Indian rope trick in the Indian press. These Sanskrit texts of Shankara are the basis for the claim that the trick is of great antiquity in India.
