Antonio Exili, an Italian, like many other alchemists of that period, had spent years in search of the philosopher's stone and the elixir of life. His vain experiments to transmute the baser metals into gold reduced him to poverty and want. His quest after these secrets had led him to study deeply the nature and composition of poisons and their antidotes. He had visited the great universities and other schools of the continent, finishing his scientific studies under a famous German chemist named Glaser. But the terrible secret of the agua tofana and of the poudre de succession, Exili learned from Beatrice Spara, a Sicilian, with whom he had a liaison, one of those inscrutable beings of the gentle *** whose lust for pleasure or power is only equalled by the atrocities they are willing to perpetrate upon all who stand in the way of their desires or their ambition.
To Beatrice Spara, the secret of this subtle preparation had come down like an evil inheritance from the ancient Candidas and Saganas of imperial Rome. In the proud palaces of the Borgias, of the Orsinis, the Scaligers, the Borromeos, the art of poisoning was preserved among the last resorts of Machiavellian statecraft; and not only in palaces, but in streets of Italian cities, in solitary towers and dark recesses of the Apennines, were still to be found the lost children of science, skilful compounders of poisons, at once fatal and subtle in their operation,--poisons which left not the least trace of their presence in the bodies of their victims, but put on the appearance of other and more natural causes of death.
Exili, to escape the vengeance of Beatrice Spara, to whom he had proved a faithless lover, fled from Naples, and brought his deadly knowledge to Paris, where he soon found congenial spirits to work with him in preparing the deadly poudre de succession, and the colorless drops of the aqua tofana.
With all his crafty caution, Exili fell at last under suspicion of the police for tampering in these forbidden arts. He was arrested, and thrown into the Bastile, where he became the occupant of the same cell with Gaudin de St. Croix, a young nobleman of the Court, the lover of the Marchioness de Brinvilliers, for an intrigue with whom the Count had been imprisoned. St. Croix learned from Exili, in the Bastile, the secret of the poudre de succession.
The two men were at last liberated for want of proof of the charges against them. St. Croix set up a laboratory in his own house, and at once proceeded to experiment upon the terrible secrets learned from Exili, and which he revealed to his fair, frail mistress, who, mad to make herself his wife, saw in these a means to remove every obstacle out of the way. She poisoned her husband, her father, her brother, and at last, carried away by a mania for murder, administered on all sides the fatal poudre de succession, which brought death to house, palace, and hospital, and filled the capital, nay, the whole kingdom, with suspicion and terror.
This fatal poison history describes as either a light and almost impalpable powder, tasteless, colorless, and inodorous, or a liquid clear as a dewdrop, when in the form of the aqua tofana. It was capable of causing death either instantaneously or by slow and lingering decline at the end of a definite number of days, weeks, or even months, as was desired. Death was not less sure because deferred, and it could be made to assume the appearance of dumb paralysis, wasting atrophy, or burning fever, at the discretion of the compounder of the fatal poison.
The ordinary effect of the aqua tofana was immediate death. The poudre de succession was more slow in killing. It produced in its pure form a burning heat, like that of a fiery furnace in the chest, the flames of which, as they consumed the patient, darted out of his eyes, the only part of the body which seemed to be alive, while the rest was little more than a dead corpse.
Upon the introduction of this terrible poison into France, Death, like an invisible spirit of evil, glided silently about the kingdom, creeping into the closest family circles, seizing everywhere on its helpless victims. The nearest and dearest relationships of life were no longer the safe guardians of the domestic hearth. The man who to-day appeared in the glow of health dropped to-morrow and died the next day. No skill of the physician was able to save him, or to detect the true cause of his death, attributing it usually to the false appearances of disease which it was made to assume.
The victims of the poudre de succession were counted by thousands.
The possession of wealth, a lucrative office, a fair young wife, or a coveted husband, were sufficient reasons for sudden death to cut off the holder of these envied blessings. A terrible mistrust pervaded all classes of society. The husband trembled before his wife, the wife before her husband, father and son, brother and sister,--kindred and friends, of all degrees, looked askance and with suspicious eyes upon one another.
In Paris the terror lasted long. Society was for a while broken up by cruel suspicions. The meat upon the table remained uneaten, the wine undrank, men and women procured their own provisions in the market, and cooked and ate them in their own apartments. Yet was every precaution in vain. The fatal dust scattered upon the pillow, or a bouquet sprinkled with the aqua tofana, looking bright and innocent as God's dew upon the flowers, transmitted death without a warning of danger. Nay, to crown all summit of wickedness, the bread in the hospitals of the sick, the meagre tables of the convent, the consecrated host administered by the priest, and the sacramental wine which he drank himself, all in turn were poisoned, polluted, damned, by the unseen presence of the manna of St.
Nicholas, as the populace mockingly called the poudre de succession.
