The popularity of sorcery in Paris towards the end of the sixteenth century is easily accounted for by the fact that kings, queens, and nobles habitually consulted astrologers. Catherine de Medicis was one of the chief believers in all kinds of superstitious practices; and a column used to be shown in the flower-market from which she observed at night the course of the stars. This credulous and cruel queen wore round her waist a skin of vellum, or, as some maintained, the skin of a child, inscribed with figures, letters, and other characters in different colours, as well as a talisman, prepared for her by the astrologer Regnier, an engraving of which may be found in the _Journal of Henry III_. By this talisman, composed as it was of human blood, goats' blood, and several kinds of metals melted and mixed together, under certain constellations associated with her birth, Catherine imagined that she could rule the present and foresee the future. Magic was employed not only for self-preservation, but with the most murderous intentions. When it was used to destroy an enemy, his effigy was prepared in wax; and the thrusts and stabs inflicted upon the figure were supposed to be felt by the original. A gentleman named Lamalle, having been executed on the Place de Grève in 1574, and a wax image, made by the magician Cosmo Ruggieri, having been found upon him, Catherine de Medicis, who patronised this charlatan, feared that the wax figure might have been designed against the life of Charles IX., and that Ruggieri would therefore be condemned to death. Lamalle had maintained that the figure was meant to represent the "Great Princess": Queen Marguerite, that is to say. But Cosmo Ruggieri was condemned, all the same, to the galleys; though his sentence--thanks, no doubt, to the personal influence of Catherine de Medicis--was never executed. Nicholas Pasquier, who gives a long account of Ruggieri in his _Public Letters_, declares that he died "a very wicked man, an atheist, and a great magician," adding that he made another wax figure, on which he poured all kinds of venoms and poisons in order to bring about the death of "our great Henry." But he was unable to attain his end; and the king, "in his sweet clemency, forgave him."
