Nicholas Flamel repaired. He left his book in Paris for fear, perhaps, that he might be robbed of it on the road; and telling his neighbours that he was going on a pilgrimage to the shrine of St. James of Compostello, he trudged on foot towards Madrid in search of a Rabbi. He was absent two years in that country, and made himself known to a great number of Jews, descendants of those who had been expelled from France in the reign of Philip Augustus. The believers in the philosopher’s stone give the following account of his adventures: — They say that at Leon he made the acquaintance of a converted Jew, named Cauches, a very learned physician, to whom he explained the title and the nature of his little book. The Doctor was transported with joy as soon as he heard it named, and immediately resolved to accompany Nicholas to Paris, that he might have a sight of it. The two set out together; the Doctor on the way entertaining his companion with the history of his book, which, if the genuine book he thought it to be, from the description he had heard of it, was in the handwriting of Abraham himself, and had been in the possession of personages no less distinguished than Moses, Joshua, Solomon, and Esdras. It contained all the secrets of alchymy and of many other sciences, and was the most valuable book that had ever existed in this world. The Doctor was himself no mean adept, and Nicholas profited greatly by his discourse, as in the garb of poor pilgrims they wended their way to Paris, convinced of their power to turn every old shovel in that capital into pure gold. But, unfortunately, when they reached Orleans, the Doctor was taken dangerously ill. Nicholas watched by his bedside, and acted the double part of a physician and nurse to him; but he died after a few days, lamenting with his last breath that he had not lived long enough to see the precious volume. Nicholas rendered the last honours to his body; and with a sorrowful heart, and not one sous in his pocket, proceeded home to his wife Petronella. He immediately recommenced the study of his pictures; but for two whole years he was as far from understanding them as ever. At last, in the third year, a glimmer of light stole over his understanding. He recalled some expression of his friend, the Doctor, which had hitherto escaped his memory, and he found that all his previous experiments had been conducted on a wrong basis. He recommenced them now with renewed energy, and at the end of the year had the satisfaction to see all his toils rewarded. On the 13th January 1382, says Lenglet, he made a projection on mercury, and had some very excellent silver. On the 25th April following, he converted a large quantity of mercury into gold, and the great secret was his.

Nicholas was now about eighty years of age, and still a hale and stout old man. His friends say that, by the simultaneous discovery of the elixir of life, he found means to keep death at a distance for another quarter of a century; and that he died in 1415, at the age of 116. In this interval he had made immense quantities of gold, though to all outward appearance he was as poor as a mouse. At an early period of his changed fortune, he had, like a worthy man, taken counsel with his old wife Petronella, as to the best use he could make of his wealth. Petronella replied, that as unfortunately they had no children, the best thing he could do, was to build hospitals and endow churches. Nicholas thought so too, especially when he began to find that his elixir could not keep off death, and that the grim foe was making rapid advances upon him. He richly endowed the church of St. Jacques de la Boucherie, near the Rue de Marivaux, where he had all his life resided, besides seven others in different parts of the kingdom. He also endowed fourteen hospitals, and built three chapels.

The fame of his great wealth and his munificent benefactions soon spread over all the country, and he was visited, among others, by the celebrated Doctors of that day, Jean Gerson, Jean de Courtecuisse, and Pierre d’Ailli. They found him in his humble apartment, meanly clad, and eating porridge out of an earthen vessel; and with regard to his secret, as impenetrable as all his predecessors in alchymy. His fame reached the ears of the King, Charles VI, who sent M. de Cramoisi, the Master of Requests, to find out whether Nicholas had indeed discovered the philosopher’s stone. But M. de Cramoisi took nothing by his visit; all his attempts to sound the alchymist were unavailing, and he returned to his royal master no wiser than he came. It was in this year, 1414, that he lost his faithful Petronella. He did not long survive her; but died in the following year, and was buried with great pomp by the grateful priests of St. Jacques de la Boucherie.

The great wealth of Nicholas Flamel is undoubted, as the records of several churches and hospitals in France can testify. That he practised alchymy is equally certain, as he left behind several works upon the subject.
