Delisle, it would appear, was afraid of venturing to Paris. He knew that his sleight of hand would be too narrowly watched in the royal presence; and upon some pretence or other he delayed the journey for more than two years. Desmarets, the Minister of Finance to Louis XIV., thinking the “philosopher” dreaded foul play, twice sent him a safe conduct under the king’s seal; but Delisle still refused. Upon this, Desmarets wrote to the Bishop of Senés for his real opinion as to these famous transmutations. The following was the answer of that prelate:
“Copy of a report addressed to M. Desmarets, Comptroller-General of the Finances to His Majesty Louis XIV., by the Bishop of Senés, dated March 1709.
“Sir,—A twelvemonth ago, or a little more, I expressed to you my joy at hearing of your elevation to the ministry; I have now the honour to write you my opinion of the Sieur Delisle, who has been working at the transmutation of metals in my diocese. I have, during the last two years, spoken of him several times to the Count de Pontchartrain, because he asked me; but I have not written to you, sir, or to M. de Chamillart, because you neither of you requested my opinion upon the subject. Now, however, that you have given me to understand that you wish to know my sentiments on the matter, I will unfold myself to you in all sincerity, for the interests of the king and the glory of your ministry.
“There are two things about the Sieur Delisle which, in my opinion, should be examined without prejudice: the one relates to his secret; the other, to his person; that is to say, whether his transmutations are real, and whether his conduct has been regular. As regards the secret of the philosopher’s stone, I deemed it impossible, for a long time; and for more than three years I was more mistrustful of the pretensions of this Sieur Delisle than of any other person. During this period I afforded him no countenance; I even aided a person, who was highly recommended to me by an influential family of this province, to prosecute Delisle for some offence or other which it was alleged he had committed. But this person, in his anger against him, having told me that he had himself been several times the bearer of gold and silver to the goldsmiths of Nice, Aix, and Avignon, which had been transmuted by Delisle from lead and iron, I began to waver a little in my opinions respecting him. I afterwards met Delisle at the house of one of my friends. To please me, the family asked Delisle to operate before me, to which he immediately consented. I offered him some iron nails, which he changed into silver in the chimney-place before six or seven credible witnesses. I took the nails thus transmuted, and sent them by my almoner to Imbert, the jeweller of Aix, who, having subjected them to the necessary trial, returned them to me, saying they were very good silver. Still, however, I was not quite satisfied. M. de Pontchartrain having hinted to me, two years previously, that I should do a thing agreeable to his majesty if I examined into this business of Delisle, I resolved to do so now. I therefore summoned the alchymist to come to me at Castellane. He came; and I had him escorted by eight or ten vigilant men, to whom I had given notice to watch his hands strictly. Before all of us he changed two pieces of lead into gold and silver. I sent them both to M. de Pontchartrain; and he afterwards informed me by a letter, now lying before me, that he had shewn them to the most experienced goldsmiths of Paris, who unanimously pronounced them to be gold and silver of the very purest quality, and without alloy. My former bad opinion of Delisle was now indeed shaken. It was much more so when he performed transmutation five or six times before me at Senés, and made me perform it myself before him without his putting his hand to any thing. You have seen, sir, the letter of my nephew, the Père Berard, of the Oratoire at Paris, on the experiment that he performed at Castellane, and the truth of which I hereby attest. Another nephew of mine, the Sieur Bourget, who was here three weeks ago, performed the same experiment in my presence, and will detail all the circumstances to you personally at Paris. A hundred persons in my diocese have been witnesses of these things. I confess to you, sir, that, after the testimony of so many spectators and so many goldsmiths, and after the repeatedly successful experiments that I saw performed, all my prejudices vanished. My reason was convinced by my eyes; and the phantoms of impossibility which I had conjured up were dissipated by the work of my own hands.
“It now only remains for me to speak to you on the subject of his person and conduct. Three suspicions have been excited against him: the first, that he was implicated in some criminal proceeding at Cisteron, and that he falsified the coin of the realm; the second, that the king sent him two safe-conducts without effect; and the third, that he still delays going to court to operate before the king. You may see, sir, that I do not hide or avoid any thing. As regards the business at Cisteron, the Sieur Delisle has repeatedly assured me that there was nothing against him which could reasonably draw him within the pale of justice, and that he had never carried on any calling injurious to the king’s service. It was true that, six or seven years ago, he had been to Cisteron to gather herbs necessary for his powder, and that he had lodged at the house of one Pelouse, whom he thought an honest man. Pelouse was accused of clipping Louis-d’ors; and as he had lodged with him, he was suspected of being his accomplice. This mere suspicion, without any proof whatever, had caused him to be condemned for contumacy; a common case enough with judges, who always proceed with much rigour against those who are absent. During my own sojourn at Aix, it was well known that a man, named André Aluys, had spread about reports injurious to the character of Delisle, because he hoped thereby to avoid paying him a sum of forty Louis that he owed him. But permit me, sir, to go further, and to add that, even if there were well-founded suspicions against Delisle, we should look with some little indulgence on the faults of a man who possesses a secret so useful to the state. As regards the two safe-conducts sent him by the king, I think I can answer certainly that it was through no fault of his that he paid so little attention to them. His year, strictly speaking, consists only of the four summer months; and when by any means he is prevented from making the proper use of them, he loses a whole year. Thus the first safe-conduct became useless by the irruption of the Duke of Savoy in 1707 and the second had hardly been obtained, at the end of June 1708, when the said Delisle was insulted by a party of armed men, pretending to act under the authority of the Count de Grignan, to whom he wrote several letters of complaint, without receiving any answer, or promise that his safety would be attended to. What I have now told you, sir, removes the third objection, and is the reason why, at the present time, he cannot go to Paris to the king, in fulfilment of his promises made two years ago. Two, or even three, summers have been lost to him, owing to the continual inquietude he has laboured under. He has, in consequence, been unable to work, and has not collected a sufficient quantity of his oil and powder, or brought what he has got to the necessary degree of perfection. For this reason also he could not give the Sieur de Bourget the portion he promised him for your inspection. If the other day he changed some lead into gold with a few grains of his powder, they were assuredly all he had; for he told me that such was the fact long before he knew my nephew was coming. Even if he had preserved this small quantity to operate before the king, I am sure that, on second thoughts, he would never have adventured with so little; because the slightest obstacles in the metals (their being too hard or too soft, which is only discovered in operating,) would have caused him to be looked upon as an impostor, if, in case his first powder had proved ineffectual, he had not been possessed of more to renew the experiment and surmount the difficulty.
“Permit me, sir, in conclusion, to repeat, that such an artist as this should not be driven to the last extremity, nor forced to seek an asylum offered to him in other countries, but which he has despised, as much from his own inclinations as from the advice I have given him. You risk nothing in giving him a little time, and in hurrying him you may lose a great deal. The genuineness of his gold can no longer be doubted, after the testimony of so many jewellers of Aix, Lyons, and Paris in its favour. As it is not his fault that the previous safe-conducts sent to him have been of no service, it will be necessary to send him another; for the success of which I will be answerable, if you will confide the matter to me, and trust to my zeal for the service of his majesty, to whom I pray you to communicate this letter, that I may be spared the just reproaches he might one day heap upon me if he remained ignorant of the facts I have now written to you. Assure him, if you please, that, if you send me such a safe-conduct, I will oblige the Sieur Delisle to depose with me such precious pledges of his fidelity as shall enable me to be responsible myself to the king. These are my sentiments, and I submit them to your superior knowledge; and have the honour to remain, with much respect, &c.
“? John Bishop of Senes.
“To M. Desmarets, Minister of State, and Comptroller-General of the Finances, at Paris.”
That Delisle was no ordinary impostor, but a man of consummate cunning and address, is very evident from this letter. The bishop was fairly taken in by his clever legerdemain, and when once his first distrust was conquered, appeared as anxious to deceive himself as even Delisle could have wished. His faith was so abundant that he made the case of his protégé his own, and would not suffer the breath of suspicion to be directed against him. Both Louis and his minister appear to have been dazzled by the brilliant hopes he had excited, and a third pass, or safe-conduct, was immediately sent to the alchymist, with a command from the king that he should forthwith present himself at Versailles, and make public trial of his oil and powder. But this did not suit the plans of Delisle. In the provinces he was regarded as a man of no small importance; the servile flattery that awaited him wherever he went was so grateful to his mind that he could not willingly relinquish it, and run upon certain detection at the court of the monarch. Upon one pretext or another he delayed his journey, notwithstanding the earnest solicitations of his good friend the bishop. The latter had given his word to the minister, and pledged his honour that he would induce Delisle to go, and he began to be alarmed when he found he could not subdue the obstinacy of that individual. For more than two years he continued to remonstrate with him, and was always met by some excuse, that there was not sufficient powder, or that it had not been long enough exposed to the rays of the sun. At last his patience was exhausted; and fearful that he might suffer in the royal estimation by longer delay, he wrote to the king for a lettre de cachet, in virtue of which the alchymist was seized at the castle of La Palu, in the month of June 1711, and carried off to be imprisoned in the Bastille.
The gendarmes were aware that their prisoner was supposed to be the lucky possessor of the philosopher’s stone, and on the road they conspired to rob and murder him. One of them pretended to be touched with pity for the misfortunes of the philosopher, and offered to give him an opportunity of escape whenever he could divert the attention of his companions. Delisle was profuse in his thanks, little dreaming of the snare that was laid for him. His treacherous friend gave notice of the success of the stratagem so far; and it was agreed that Delisle should be allowed to struggle with and overthrow one of them while the rest were at some distance. They were then to pursue him and shoot him through the heart; and after robbing the corpse of the philosopher’s stone, convey it to Paris on a cart, and tell M. Desmarets that the prisoner had attempted to escape, and would have succeeded if they had not fired after him and shot him through the body. At a convenient place the scheme was executed. On a given signal from the friendly gendarme, Delisle fled, while another gendarme took aim and shot him through the thigh. Some peasants arriving at the instant, they were prevented from killing him as they intended, and he was transported to Paris, maimed and bleeding. He was thrown into a dungeon in the Bastille, and obstinately tore away the bandages which the surgeons applied to his wound. He never afterwards rose from his bed.
The Bishop of Senés visited him in prison, and promised him his liberty if he would transmute a certain quantity of lead into gold before the king. The unhappy man had no longer the means of carrying on the deception; he had no gold, and no double-bottomed crucible or hollow wand to conceal it in, even if he had. He would not, however, confess that he was an impostor; but merely said he did not know how to make the powder of projection, but had received a quantity from an Italian philosopher, and had used it all in his various transmutations in Provence. He lingered for seven or eight months in the Bastille, and died from the effects of his wound, in the forty-first year of his age.
Albert Aluys.
This pretender to the philosopher’s stone was the son, by a former husband, of the woman Aluys, with whom Delisle became acquainted at the commencement of his career, in the cabaret by the road-side, and whom he afterwards married. Delisle performed the part of a father towards him, and thought he could shew no stronger proof of his regard, than by giving him the necessary instructions to carry on the deception which had raised himself to such a pitch of greatness. The young Aluys was an apt scholar, and soon mastered all the jargon of the alchymists. He discoursed learnedly upon projections, cimentations, sublimations, the elixir of life, and the universal alkahest; and on the death of Delisle gave out that the secret of that great adept had been communicated to him, and to him only. His mother aided in the fraud, with the hope they might both fasten themselves, in the true alchymical fashion, upon some rich dupe, who would entertain them magnificently while the operation was in progress. The fate of Delisle was no inducement for them to stop in France. The Provençals, it is true, entertained as high an opinion as ever of his skill, and were well inclined to believe the tales of the young adept on whom his mantle had fallen; but the dungeons of the Bastille were yawning for their prey, and Aluys and his mother decamped with all convenient expedition. They travelled about the Continent for several years, sponging upon credulous rich men, and now and then performing successful transmutations by the aid of double-bottomed crucibles and the like. In the year 1726, Aluys, without his mother, who appears to have died in the interval, was at Vienna, where he introduced himself to the Duke de Richelieu, at that time ambassador from the court of France. He completely deceived this nobleman; he turned lead into gold (apparently) on several occasions, and even made the ambassador himself turn an iron nail into a silver one. The duke afterwards boasted to Lenglet du Fresnoy of his achievements as an alchymist, and regretted that he had not been able to discover the secret of the precious powder by which he performed them.
Aluys soon found that, although he might make a dupe of the Duke de Richelieu, he could not get any money from him. On the contrary, the duke expected all his pokers and fire-shovels to be made silver, and all his pewter utensils gold; and thought the honour of his acquaintance was reward sufficient for a roturier, who could not want wealth since he possessed so invaluable a secret. Aluys, seeing that so much was expected of him, bade adieu to his excellency, and proceeded to Bohemia accompanied by a pupil, and by a young girl who had fallen in love with him in Vienna. Some noblemen in Bohemia received him kindly, and entertained him at their houses for months at a time. It was his usual practice to pretend that he possessed only a few grains of his powder, with which he would operate in any house where he intended to fix his quarters for the season. He would make the proprietor the present of a piece of gold thus transmuted, and promise him millions, if he could only be provided with leisure to gather his lunaria major and minor on their mountain-tops, and board, lodging, and loose cash for himself, his wife, and his pupil, in the interval.
He exhausted in this manner the patience of some dozen of people, when, thinking that there was less danger for him in France under the young king Louis XV. than under his old and morose predecessor, he returned to Provence. On his arrival at Aix, he presented himself before M. le Bret, the president of the province, a gentleman who was much attached to the pursuits of alchymy, and had great hopes of being himself able to find the philosopher’s stone. M. le Bret, contrary to his expectation, received him very coolly, in consequence of some rumours that were spread abroad respecting him; and told him to call upon him on the morrow. Aluys did not like the tone of the voice, or the expression of the eye of the learned president, as that functionary looked down upon him. Suspecting that all was not right, he left Aix secretly the same evening, and proceeded to Marseilles. But the police were on the watch for him; and he had not been there four-and-twenty hours, before he was arrested on a charge of coining, and thrown into prison.
As the proofs against him were too convincing to leave him much hope of an acquittal, he planned an escape from durance. It so happened that the gaoler had a pretty daughter, and Aluys soon discovered that she was tender-hearted. He endeavoured to gain her in his favour, and succeeded. The damsel, unaware that he was a married man, conceived and encouraged a passion for him, and generously provided him with the means of escape. After he had been nearly a year in prison he succeeded in getting free, leaving the poor girl behind to learn that he was already married, and to lament in solitude that she had given her heart to an ungrateful vagabond.
