Fioraventi was a famous Italian quack in the latter half of the seventeenth century. He practised in Naples, Rome, Venice, Milan, and Florence, and was specially honoured in his native city of Bologna, where he was made a Doctor, a Chevalier, and a Count; titles of which he made the utmost use. He published numerous works on medicine, devised various “Nostra,” and pretended to give the exact formulas for these, but they were always so complicated that no doubt the rich clients whose patronage Fioraventi cultivated would prefer to buy the remedies ready compounded. His medical advice though crammed with bombast was generally sensible, but in all cases he recommended one or another of “our” remedies. These included “our Balm Artificiall” (the compound just referred to), “our Electuaria Anglico,” “our Sirrup Solutivo,” “our Lignum Sanctum,” “our Oleum Benedictum,” and so forth. Above all Fioraventi made play with his “Petra Philosophale.” Philosophers had long disputed, he says, whether it was possible to produce a medicine which would cure all diseases. There was no longer any occasion for dispute; the discovery of “our Petra Philosophale” was conclusive. The directions for making this remedy were very complicated, and of course it was essential that they should be followed minutely. Briefly, the process was to take so much “Sal Niter, Roche Allum, and Roman Vitrioll” (I take the names from an old English translation), “add some Sal Gemmæ, and distil. Then mix Mercury, Sope, Quick Lime, and Common Ashes, sublime off the Mercury, and add it to the first distillate. To the mixture add so much steel, iron, and gold, dry the compound to a stone, which ‘keep as a precious Jewell’ in a closed glass vessel.” Why Fioraventi should have troubled to invent any other remedies after this, or why his patients should have been called upon to buy any others, is not explained. BAUME TRANQUILLE was originally made by the Capucin monk, Aignan, whose religious name was Father Tranquille. The Capucins of the Louvre were noted in the seventeenth century for their medical skill, and Father Tranquille was one of them. Twenty herbs were used in compounding this balsam, among them poppy, tobacco, lavender, and rue. These were infused in oil. “The Baume may be made still more effective,” writes Père Rousseau, who was a fellow monk with Father Tranquille, “by adding as many large live frogs as there are pounds of oil. These are to be boiled in the oil until they are almost burnt. Their juice and fat combine with the oil and greatly augment the excellence of the remedy.” Mme. de Sévigné, writing to her daughter, December 15, 1684, says, “I am sending you the most precious treasure I have: my half bottle of Baume Tranquille. I could not send a full bottle; the Capucins have no more.” BAUME DE VIE.
