TRANSMUTATION OF METALS.

Among the different pursuits, which engaged the curiosity of active minds in these unenlightened ages, was that of the transmutation of the more ordinary metals into gold and silver. This art, though not properly of necromantic nature, was however elevated by its professors, by means of an imaginary connection between it and astrology, and even between it and an intercourse with invisible spirits. They believed, that their investigations could not be successfully prosecuted but under favourable aspects of the planets, and that it was even indispensible to them to obtain supernatural aid.

In proportion as the pursuit of transmutation, and the search after the elixir of immortality grew into vogue, the adepts became desirous of investing them with the venerable garb of antiquity. They endeavoured to carry up the study to the time of Solomon; and there were not wanting some who imputed it to the first father of mankind. They were desirous to track its footsteps in Ancient Egypt; and they found a mythological representation of it in the expedition of Jason after the golden fleece, and in the cauldron by which Medea restored the father of Jason to his original youth. But, as has already been said, the first unquestionable mention of the subject is to be referred to the time of Dioclesian. From that pea Wotton, Reflections on Learning, Chap. X. b See above, p. 29.

irod traces of the studies of the alchemists from time to time regularly discover themselves.

The study of chemistry and its supposed invaluable results was assiduously cultivated by Geber and the Arabians.

ARTEPHIUS.

Artephius is one of the earliest names that occur among the students who sought the philosopher's stone. Of him extraordinary things are told. He lived about the year 1130, and wrote a book of the Art of Prolonging Human Life, in which he professes to have already attained the age of one thousand and twenty-five years". He must by this account have been born about one hundred years after our Saviour. He professed to have visited the infernal regions, and there to have seen Tantalus seated on a throne of gold. He is also said by some to be the same person, whose life has been written by Philostratus under the name of Apollonius of Tyana'. He wrote a book on the philosopher's stone, which was published in Latin and French at Paris in the year 1612.

RAYMOND LULLI.

Among the European students of these interesting secrets a foremost place is to be assigned to Raymond Lulli and Arnold of Villeneuve.

Lulli was undoubtedly a man endowed in a very eminent degree with the powers of intellect. He was a native of the island of Majorca, and was born in the year 1234. He is said to have passed his early years in profligacy and dissipation, but to have been reclaimed by the accident of falling in love with a young woman afflicted with a cancer. This circumstance induced him to apply himself intently to the study of chemistry and medicine, with a view to discover a cure for her complaint, in which he succeeded. He afterwards entered into the community of Franciscan friars.

Edward the First was one of the most extraordinary princes that ever sat on a throne. He revived the study of the Roman civil law with such success as to have merited the title of the English Justinian. He was no less distinguished as the patron of arts and letters. He invited to

England Guido dalla Colonna, the author of the Troy Book, and Raymond Lulli. This latter was believed in his time to have prosecuted his studies with such success as to have discovered the elixir vitæ, by means of which he could keep off the assaults of old age, at least for centuries, and the philosopher's stone. He is affirmed by these means to have supplied to Edward the First six millions of money, to enable him to carry on war against the Turks.

But he was not only indefatigable in the pursuit of natural science. He was also seized with an in

vincible desire to convert the Mahometans to the Christian faith. For this purpose he entered earnestly upon the study of the Oriental languages. He endeavoured to prevail on different princes of Europe to concur in his plan, and to erect colleges for the purpose, but without success. He at length set out alone upon his enterprise, but met with small encouragement. He penetrated into Africa and Asia. He made few converts, and was with difficulty suffered to depart, under a solemn injunction that he should not return. But Lulli chose to obey God rather than man, and ventured a second time. The Mahometans became exasperated with his obstinacy, and are said to have stoned him to death at the age of eighty years. His body was however transported to his native place; and miracles are reported to have been worked at his tomb".

Raymond Lulli is beside famous for what he was pleased to style his Great Art. The ordinary accounts however that are given of this art assume a style of burlesque, rather than of philosophy. He is said to have boasted that by means of it he could enable any one to argue logically on any subject for a whole day together, independently

of any previous study of the subject in debate. To the details of the process Swift seems to have been indebted for one of the humorous projects described by him in his voyage to Laputa. Lulli recom

mended that certain general terms of logic, metaphysics, ethics or theology should first be collected. These were to be inscribed separately upon square pieces of parchment. They were then to be placed on a frame so constructed that by turning a handle they might revolve freely, and form endless combinations. One term would stand for a subject, and another for a predicate. The student was then diligently to inspect the different combinations that fortuitously arose, and exercising the subtlety of his faculties to select such as he should find best calculated for his purposes. He would thus carry on the process of his debate; and an extraordinary felicity would occasionally arise, suggesting the most ingenious hints, and leading on to the most important discoveries".-If a man with the eminent faculties which Lulli otherwise appeared to have possessed really laid down the rules of such an art, all he intended by it must have been to satirize the gravity with which the learned doctors of his time carried on their grave disputations in mood and figure, having regard only to the severity of the rule by which they debated, and holding themselves totally indifferent whether they made any real advances in the discovery of truth.

ARNOLD OF VILLENEUVE.

Arnold of Villeneuve, who lived about the same time, was a man of eminent attainments.
