CONJURING  , the See also:

art, sometimes called See also:White or Natural Magic, and See also:long associated with the profession of " magician," consisting of the performance of tricks and illusions, with or without apparatus . Historically this art has taken many forms, and has been mixed up with the use of what now are regarded as natural though obscure See also:physical phenomena . The employment of purely See also:manual dexterity without See also:mechanical apparatus may be distinguished as See also:legerdemain, See also:prestidigitation or sleight of See also:hand . Whether or not the See also:book of See also:Exodus makes the earliest See also:historical reference to this See also:form of natural " magic " when it records how the magicians of See also:Egypt imitated certain miracles of See also:Moses "by their enchantments," it is known that the See also:Egyptian hierophants, as well as the magicians of See also:ancient See also:Greece and See also:Rome, were accustomed to astonish their dupes with See also:optical illusions, visible representations of the divinities and subdivinities passing before the spectators in dark subterranean See also:chambers . The See also:principal optical illusion employed in these effects was the throwing of spectral images upon the See also:smoke of burning See also:incense by means of See also:concave See also:metal mirrors . But according to See also:Hippolytus (Ref . Om . Haer. iv . 35), the desired effect was often produced in a simpler way, by causing the dupe to look into a cellar through a See also:basin of See also:water with a See also:glass bottom See also:standing under a See also:sky-See also:blue See also:ceiling, or by figures on a dark See also:wall See also:drawn in inflammable material and suddenly ignited . The flashes of See also:lightning and the See also:rolling thunders which sometimes accompanied these manifestations were easy tricks, now See also:familiar to everybody as the ignition of See also:lycopodium and the shaking of a See also:sheet of metal . The ancient methods described by Hippolytus (iv . 32) were very similar .

Judging from the accounts which See also:

history has handed down to us, the marvels performed by the thaumaturgists of antiquity were very skilfully produced, and must have required a considerable See also:practical knowledge of the art . The See also:Romans were in the See also:habit of giving conjuring exhibitions, the most favourite feat being that of, the " cups and balls," the performers of which were called acetabularii, and the cups themselves acetabula . The balls used, however, instead of being the convenient See also:light See also:cork ones employed by See also:modern conjurors, were simply See also:round white pebbles which must have added greatly to the difficulty of performing the See also:trick . The art survived the barbarism and See also:ignorance of the See also:middle ages; and the earliest professors of the modern school were Italians such as See also:Jonas, Androletti and See also:Antonio Carlotti . But towards the See also:close of See also:Elizabeth's reign conjurors were classed with "ruffians, blasphemers, thieves, vagabonds, See also:Jews, See also:Turks, heretics, pagans and sorcerers." The history of conjuring by mechanical effects and inventions is full of curious detail . Spectral pictures or reflections of moving See also:objects, similar to those of the See also:camera or magic See also:lantern, were described in the 14th and 16th centuries . Thus, in the See also:House of Fame, bk. iii., See also:Chaucer speaks of " appearances such as the subtil tregetours perform at feasts "—pictorial representations of See also:hunting, See also:falconry and knights jousting, with the persons and objects instantaneously disappearing; exhibitions of the same See also:kind are mentioned by See also:Sir See also:John See also:Mandeville, as seen by him at the See also:court of " the See also:Great Chan " in See also:Asia; and in the middle of the 16th See also:century Benvenuto See also:Cellini saw phantasmagoric spectres projected upon smoke at a nocturnal See also:exhibition in the Colosseum at Rome . The existence of a camera obscura at this latter date is a fact; for the See also:instrument is described by Baptista Porta, the Neapolitan philosopher, in his Magia Naturalis (1558) . And the doubt how magic lantern effects could have been produced in the 14th century, when the lantern itself is alleged to have been invented by See also:Athanasius See also:Kircher in the middle of the 17th century, is set at See also:rest by the fact that glass lenses were constructed at the earlier of these See also:dates,—See also:Roger See also:Bacon, in his See also:Discovery of the Miracles of Art, Nature and Magic (about 126o), See also:writing of glass lenses and perspectives so well made as to give See also:good telescopic and microscopic effects, and to be useful to old men .and those who have weak eyes . Towards the end of the 18th century See also:Comus, a See also:French conjuror, included in his entertainment a figure which suddenly appeared and disappeared about three ft. above a table,—a trick explained by the circumstance that a concave See also:mirror was among his properties; and a contemporary performer, See also:Robert, exhibited the raising of the dead by the same agency . See also:Early in the 19th century Philipstal gave a sensation to his magic lantern entertainment by lowering unperceived between the See also:audience and the See also:stage a sheet of See also:gauze upon which See also:fell the vivid moving shadows of See also:phantasmagoria . A new era in optical tricks began in 1863 when John Nevil See also:Maskelyne (b .

1839), of See also:

Cheltenham, invented a See also:wood See also:cabinet in which persons vanished and were made to reappear, although it was placed upon high feet, with no passage through which a See also:person could pass from the cabinet to the stage See also:floor, the scenes, or the ceiling; and this cabinet was examined and measured for concealed space, and watched round by persons from the audience during the whole of the transformations . The See also:general principle was this: if a looking-glass be set upright in the corner of a See also:room, bisecting the right See also:angle formed by the walls, the See also:side wall reflected will appear as if it were the back, and hence an See also:object may be hidden behind the glass, yet the space seem to remain unoccupied . This principle, however, was so carried out that no sign of the existence of any mirror was discernible under the closest inspection . Two years later the same See also:simple principle appeared in " The Cabinet of See also:Proteus," patented by See also:Tobin and See also:Pepper of the See also:Polytechnic Institution, in which two mirrors were employed, See also:meeting in the middle, where an upright See also:pillar concealed their edges . In the same See also:year Stodare exhibited the illusion in an extended form, by placing the pair of mirrors in the centre of the stage, supported between the legs of a three-legged table having the See also:apex towards the audience; and as the side walls of his stage were draped exactly like the back, reflection showed an apparently clear space below the table See also:top, where in reality a See also:man in a sitting position was hidden behind the glasses and exhibited his See also:head (" The See also:Sphinx ") above the table . The See also:plane mirror illusion is so effective that it has been reproduced with modifications by various performers . In one See also:case a living bust was shown through an See also:aperture in a looking-glass sloping upward from the front towards the back of a curtained cabinet; in another a person stood See also:half-hidden by a See also:vertical mirror, and See also:imitation limbs placed in front of it were sundered and removed; and in another case a large vertical mirror was pushed forward from a back corner of the stage at an angle of 45 degrees, to See also:cover the entrance of a living " phantom," and then withdrawn . Maskelyne improved upon his See also:original cabinet by taking out a shelf which, in See also:conjunction with a mirror, could enclose a space, and thus See also:left no apparent See also:place in which a person could possibly be hidden . He introduced a further mystification by secretly conveying a person behind a See also:curtain See also:screen, notwithstanding that, during the whole See also:time, the existence of a clear space under the See also:stool upon which the screen is placed is proved by performers continually walking round . The principle of reflecting by means of transparent See also:plate-glass the images of highly-illuminated objects placed in front, so that they appear as if among less brilliantly lighted objects behind the glass, was employed in the " See also:ghost " illusions of See also:Sylvester, of Dircks and Pepper, of See also:Robin, and of some other inventors,—the transparent plate-glass being, in some cases, inclined forwards so as to reflect a See also:lime-lighted object placed below the front of the stage, and in other arrangements set vertically at an angle so as to reflect the object, from a lateral position . Among the acoustic wonders of antiquity were the speaking head of See also:Orpheus, the See also:golden virgins, whose voices resounded through the See also:temple of See also:Delphi, and the like . Hippolytus (iv .

4) explains the trick of the speaking head as practised in his See also:

day, the See also:voice being really that of a concealed assistant who spoke through the flexible gullet of a See also:crane . Towards the close of the loth century See also:Gerbert (See also:Pope See also:Silvester II.) constructed (says See also:William of See also:Malmesbury) a brazen head which answered questions; and similar inventions are ascribed to Roger Bacon, Albertus See also:Magnus, and others . In the first half of the 17th century the philosopher See also:Descartes made a speaking figure which he called his daughter Franchina; but the superstitious See also:captain of a See also:vessel had it thrown overboard . In the latter See also:part of the same century See also:Thomas Irson, an Englishman, exhibited at the court of See also:Charles II. a wooden figure with a speaking-See also:trumpet in its mouth; and questions whispered in its See also:ear were answered through a See also:pipe secretly communicating with an apartment wherein was a learned See also:priest able to converse in various See also:languages . Johann See also:Beckmann, in his History of Inventions (about 1770, Eng. transi. by W . See also:Johnston, 4th ed.,1846), relates his inspection of a speaking figure, in which the words really came through a See also:tube from a confederate who held a card of signs by which he received intelligence from the exhibitor . Somewhat later was shown in See also:England the figure of an See also:infant suspended by a ribbon, having a speaking-trumpet in its mouth,—an illusion in which two concave mirrors were employed, one of them concentrating the rays of See also:sound into a See also:focus within the head of the figure; and the mirror nearest the figure was hidden by a portion of the wall-See also:paper which was perforated with See also:pin-holes . In 1783 Giuseppe Pinetti de Wildalle, an See also:Italian conjuror of great originality, exhibited among his many wonders a See also:toy See also:bird perched upon a See also:bottle, which fluttered, blew out a See also:candle, and warbled any See also:melody proposed or improvised by the audience,—doing this also when removed from the bottle to a table, or when held in the performer's hand upon any part of the stage . The sounds were produced by a confederate who imitated See also:song-birds after Rossignol's method by aid of the inner skin of an See also:onion in the mouth; and speaking-trumpets directed the sounds to whatever position was occupied by the bird . About the year 1825 Charles, a Frenchman, exhibited a See also:copper globe, carrying four speaking-trumpets, which was suspended in a light See also:frame in the centre of a room . Whispers uttered near to this apparatus were heard by a confederate in an adjoining room by means of a tube passing through the frame and the floor, and answers issued from the trumpets in a loud See also:tone . Subsequently appeared more than one illusion of a similar See also:order, in which the talking and singing of a distant person issued from an isolated head or figure by aid of ear-trumpets secretly contained within parts in which, from their outside form, the presence of such See also:instruments would not be suspected .

It is probable that the See also:

automaton trumpeters of See also:Friedrich See also:Kaufmann and of Johann See also:Nepomuk Malzel were See also:clever deceptions of the same kind . As described in the See also:Journal de Mode, 1809, Malzel's See also:life-See also:size figure had the musical instrument fixed in its mouth; the mechanism was See also:wound up, and a set See also:series of See also:marches, See also:army calls, and other compositions was performed, accompaniments being played by a real See also:band . Mechanical counterparts of the human lips, See also:tongue and breath, both in speech and in playing certain musical instruments, have, however, been constructed, as in Jacques de Vaucanson's celebrated automaton See also:flute-player, which was completed in 1736; the same mechanician's See also:tambourine and See also:flageolet player, which was still more ingenious, as, the flageolet having only three holes, some of the notes were produced by half-stopping; See also:Abbe Mical's heads which articulated syllables, and his automata playing upon instruments; Kempelen's and Kratzenstein's speaking-See also:machines, in the latter part of the 18th century; the speaking-See also:machine made by Fabermann of See also:Vienna, closely imitating the human voice, with a fairly good See also:pronunciation of various words; the automaton clarionet-player constructed by See also:Van Oeckelen, a Dutchman, and exhibited in New See also:York in 186o, which played airs from a See also:barrel like that of a See also:crank-See also:organ, and could take the clarion( from its mouth and replace it, and Maskelyne's two automata, " Fanfare " (1878) playing a See also:cornet, and " Labial " (1879) playing a See also:euphonium, both operated by mechanism inside the figures and supplied with See also:wind from a See also:bellows placed separately upon the stage . See also:Lucian tells of the magician See also:Alexander in the 2nd century that he received written questions enclosed in sealed envelopes, and a few days afterwards delivered written responses in the same envelopes, with the See also:seals apparently unbroken; and both he and Hippolytus explain several methods by which this could be effected . In this deception we have the germ of " spirit-See also:reading " and " spirit-writing," which, introduced in 1840 by John See also:Henry See also:Anderson, " The Wizard of the See also:North," became See also:common in the repertoire of modern conjurors,—embracing a variety of effects from an instantaneous substitution which allows the performer or his confederate to see what has been secretly written by the audience . The so-called "second-sight" trick depends upon a See also:system of signalling between the exhibitor, who moves among the audience See also:collecting questions to be answered and articles to be described, and the performer, who is See also:blind-folded on the stage . As already stated, the speaking figure which Stock showed to See also:Professor Beckmann, at See also:Gottingen, about 1770, was instructed by a See also:code of signals . In 1783 Pinetti had an automaton figure about 18 in. in height, named the See also:Grand See also:Sultan or See also:Wise Little Turk, which answered questions as to chosen See also:cards and many other things by striking upon a See also:bell, intelligence being communicated to a confederate by an ingenious ordering of the words, syllables or vowels in the questions put . The teaching of See also:Mesmer and the feats of See also:clairvoyance suggested to Pinetti a more remarkable performance in 1785, when Signora Pinetti, sitting blindfold in a front See also:box of a See also:theatre, replied to questions and displayed her knowledge of'articles in the See also:possession of the audience . Half a century later this was See also:developed with greater elaboration, and the system of telegraphing cloaked by intermixing signals on other methods, first by Robert-Houdin in 1846, then by See also:Hermann in 1848, and by Anderson at a later See also:period . Details of the system of indicating a very large number of answers by slight and unperceived See also:variations in the form of question are given by F . A .

Gandon, La seconde vue devoilee (See also:

Paris, 1849) . See also:Fire tricks, such as walking on burning coals, breathing See also:flame and smoke from a See also:gall-See also:nut filled with an inflammable See also:composition and wrapped in See also:tow, or dipping the hands in boiling See also:pitch, were known in early times, and are explained by Hippolytus (iv . 33) . At the close of the 17th century See also:Richard-son astonished the See also:English public by chewing ignited coals, pouring melted See also:lead (really quicksilver) upon his tongue and swallowing melted glass . See also:Strutt, in See also:Sports and Pastimes of the See also:People of England, relates how he saw Powel the fireeater, in 1762, broil a piece of beefsteak laid upon his tongue,—a piece of lighted See also:charcoal being placed under his tongue which a spectator blew upon with a bellows till the See also:meat was sufficiently done . This man also drank a melted mixture of pitch, See also:brimstone and lead out of an See also:iron See also:spoon, the stuff blazing furiously . These performers anointed their mouths and See also:tongues with a protective composition . See also:Galen speaks of a person in the 2nd century who relighted a blown-out candle by holding it against a wall or a See also:stone which had been rubbed with See also:sulphur and See also:naphtha; and the instantaneous See also:lighting of candles became a famous feat of later times . Baptista Porta gave directions for performing a trick entitled " many candles shall be lighted presently." See also:Thread is boiled in oil with brimstone and See also:orpiment, and when dry See also:bound to the wicks of candles; and, one being lighted, the flame runs to them all . He says that on festival days they are wont to do this among the Turks . " Some See also:call it See also:Hermes his ointment." In 1783 Pinetti showed two figures sketched upon a wall, one of which put out a candle, and the other relighted the hot See also:wick, when the candle was held to their mouths . By wafers he had applied a few grains of See also:gunpowder to the mouth of the first, and a See also:bit of See also:phosphorus to that of the other .

A striking trick of this conjuror was to extinguish two See also:

wax candles and simultaneously light two others at a distance of 3 ft., by firing a See also:pistol . The candles were placed in a See also:row, and the pistol fired from the end where the lighted candles were placed; the sudden blast of hot See also:gas from the pistol blew out the flames and lighted the more distant candles, because in the wick of each was placed a See also:millet-See also:grain of phosphorus . A more See also:recent conjuror showed a See also:pretty illusion by appearing to carry a flame invisibly between his hands from a lighted to an unlighted candle . What he did was to hold a piece of See also:wire for a second or two in the flame of the first candle, and then See also:touch with the heated wire a bit of phosphorus which had been inserted in the See also:turpentine-wetted wick of the other . But in 1842 See also:Ludwig Dobler, a See also:German conjuror of much originality, surprised his audience by lighting two See also:hundred candles instantaneously upon the firing of a pistol . This was the earliest application of See also:electricity to stage illusions . The candles were so arranged that each wick, See also:black from previous burning, stood a few inches in front of a See also:fine nozzle gas-burner projecting horizontally from a pipe of See also:hydrogen gas, and the two hundred jets of gas passed through the same number of gaps in a conducting-wire . An electric current leaping in a spark through each See also:jet of gas ignited all simultaneously, and the gas flames fired the candle wicks . J . E . Robert-Houdin (1805-1871), who opened his " Temple of Magic " at Paris in 1845, originated the application of See also:electromagnetism for secretly working or controlling mechanical apparatus in stage illusions . His Soirees fantastiques at Paris gave him such a reputation that the French See also:government actually sent him to See also:Algiers in order to show his superiority to the See also:local marabouts; and he ranks as the founder of modern conjuring .

He first exhibited in 1845 his light and heavy See also:

chest, which, when placed upon the broad See also:plank or " See also:rake " among the spectators, and exactly over a powerful electromagnet hidden under the See also:cloth covering of the plank, was held fast at See also:pleasure . In order to divert suspicion, Houdin showed a second experiment with the same box, suspending it by a rope which passed over a single small See also:pulley attached to the ceiling; but any person in the audience who took hold of the rope to feel the sudden increase in the See also:weight of the box was unaware that the rope, while appearing to pass simply over the pulley, really passed upward over a winding-barrel worked as required by an assistant . Remarkable ingenuity was displayed in concealing a small electromagnet in the handle of his glass bell, as well as in his See also:drum, the electric current passing through wires hidden within the See also:
