To make our catalogue of supernatural doings, and the lawless
imaginations of man, the more complete, it may be further necessary to
refer to the craft, so eagerly cultivated in successive ages of the
world of converting the inferior metals into gold, to which was
usually joined the _elixir vitae_, or universal medicine, having
the quality of renewing the youth of man, and causing him to live for
ever. The first authentic record on this subject is an edict of
Dioclesian about three hundred years after Christ, ordering a diligent
search to be made in Egypt for all the ancient books which treated of
the art of making gold and silver, that they might without distinction
be consigned to the flames. This edict however necessarily presumes a
certain antiquity to the pursuit; and fabulous history has recorded
Solomon, Pythagoras and Hermes among its distinguished votaries. From
this period the study seems to have slept, till it was revived among
the Arabians after a lapse of five or six hundred years.
It is well known however how eagerly it was cultivated in various
countries of the world for many centuries after it was divulged by
Geber. Men of the most wonderful talents devoted their lives to the
investigation; and in multiplied instances the discovery was said to
have been completed. Vast sums of money were consumed in the fruitless
endeavour; and in a later period it seems to have furnished an
excellent handle to vain and specious projectors, to extort money from
those more amply provided with the goods of fortune than themselves.
The art no doubt is in itself sufficiently mystical, having been
pursued by multitudes, who seemed to themselves ever on the eve of
consummation, but as constantly baffled when to their own apprehension
most on the verge of success. The discovery indeed appears upon the
face of it to be of the most delicate nature, as the benefit must
wholly depend upon its being reserved to one or a very few, the object
being unbounded wealth, which is nothing unless confined. If the power
of creating gold is diffused, wealth by such diffusion becomes
poverty, and every thing after a short time would but return to what
it had been. Add to which, that the nature of discovery has ordinarily
been, that, when once the clue has been found, it reveals itself to
several about the same period of time.
The art, as we have said, is in its own nature sufficiently mystical,
depending on nice combinations and proportions of ingredients, and
upon the addition of each ingredient being made exactly in the
critical moment, and in the precise degree of heat, indicated by the
colour of the vapour arising from the crucible or retort. This was
watched by the operator with inexhaustible patience; and it was often
found or supposed, that the minutest error in this respect caused the
most promising appearances to fail of the expected success. This
circumstance no doubt occasionally gave an opportunity to an artful
impostor to account for his miscarriage, and thus to prevail upon his
credulous dupe to enable him to begin his tedious experiment again.
But, beside this, it appears that those whose object was the
transmutation of metals, very frequently joined to this pursuit the
study of astrology, and even the practice of sorcery. So much delicacy
and nicety were supposed to be required in the process for the
transmutation of metals, that it could not hope to succeed but under a
favourable conjunction of the planets; and the most flourishing
pretenders to the art boasted that they had also a familiar
intercourse with certain spirits of supernatural power, which assisted
them in their undertakings, and enabled them to penetrate into things
undiscoverable to mere human sagacity, and to predict future events.
