Later on Nostradamus conjured up a vision of the future king of France in a magic mirror, for the benefit of Marie de Medeci. This illusion was effected by mirrors adroitly concealed amid hanging draperies. In the sixteenth century conjurers wandered from place to place, exhibiting their tricks at fairs, in barns, and at the castles of noblemen. They were little more than strolling gypsies or vagabonds. Reginald Scott, in his _Discoverie of Witchcraft_ (1584), enumerates some of the stock feats of these mountebanks. The list includes, “swallowing a knife; burning a card and reproducing it from the pocket of a spectator; passing a coin from one pocket to another; converting money into counters, or counters into money; conveying money into the hand of another person; making a coin pass through a table or vanish from a handkerchief; tying a knot and undoing it ‘by the power of words’; taking beads from a string, the ends of which are held fast by another person; making a coin to pass from one box to another; turning wheat into flour ‘by the power of {17} words’; burning a thread and making it whole again; pulling ribbons from the mouth; thrusting a knife into the head of a man; putting a ring through the cheek, and cutting off a person’s head and restoring it to its former position.” Conjuring with cups and balls belongs to this list. [Illustration: EIGHTEENTH CENTURY CONJURER PERFORMING THE CUP-AND-BALL TRICK. (From an Old Print, Ellison Collection.)] The conjurer of the sixteenth century, and even of later date, wore about his waist a sort of bag, called _gibécière_, from its resemblance to a game bag, ostensibly to hold his paraphernalia. While delving into this bag for various articles to be used in his tricks, the magician succeeded in making substitutions and secretly getting possession of eggs, coins, balls, etc. It was a very clumsy device, but indispensable for an open-air {18} performer, who usually stood encircled by the spectators. Finally, the suspicious-looking _gibécière_ was abandoned by all save strolling mountebanks, and a table with a long cloth substituted. This table concealed an assistant, who made the necessary transformations required in the act, by means of traps and other devices. Comus, the elder, in the eighteenth century, abandoned the long table covers and the concealed assistant for the _servante_. But his immediate competitors still adhered to the draped tables, and a whole generation of later conjurers, among whom may be mentioned Comte, Bosco and Phillippe, followed their example. Robert-Houdin struck the keynote of reform in 1844. He sarcastically called the suspiciously draped table a _boite à compère_ (wooden confederate).
