Conjurers in the seventeenth century were frequently known as _Hocus Pocus_. These curious words first occur in a pamphlet printed in 1641, in which the author, speaking of the sights of Bartholomew fair, mentions “_Hocus Pocus_, with three yards of tape or ribbon in his hand, showing his art of legerdemain.” The seventeenth century is the age of the strolling mountebank, who performed wherever he could get an audience—in the stable, barnyard, street or fair. From him to the prestidigitateur of the theatre is a long step, but no longer than from the barnstorming actor to the artist of the well-appointed playhouse. There is evolution in everything. It was not until the eighteenth century that conjuring became a legitimate profession. This was largely owing to the fact that men of gentle birth, well versed in the science of the age, took up the magic wand, and gave the art dignity and respectability. It was not until the eighteenth century that natural magic was shorn of charlatanism, but even then the great Pinetti pretended to the occult in his exhibition of so-called “second sight.” He always avoided the Papal States, taking warning from the fate of Cagliostro. Magic and spiritism were in bad odor in the dominions of the Pope. Towards the middle of the century we hear of Jonas, Carlotti, Katerfelto, Androletti, Philadelphia, Rollin, Comus I and II. Comus II was famous for coining hard words. He advertised in London, “various uncommon experiments with his Enchanted Horologium, Pyxidees Literarum, {19} and many curious operations in Rhabdology, Steganography and Phylacteria, with many wonderful performances on the grand Dodecahedron, also Chartomantic Deceptions and Kharamatic Operations. To conclude with the performance of the Teretopaest Figure and Magical House; the like never seen in this kingdom before; and will astonish every beholder.” These magical experiments were doubtless very simple. What puzzled the spectators must have been the names of the tricks. Rollin, a Frenchman, after accumulating a fortune, purchased the chateau of Fontenoy-aux-Roses, in the department of the Seine. He was denounced under the Red Terror, and suffered death by the guillotine, in 1793. When the warrant for his execution was read to him, he remarked, with a smile, “That is the first paper I cannot conjure away.” III. I now come to the Count Edmond de Grisy, Pinetti’s great rival in the field of conjuring.
