History of the Intellectual Development of Europe, Volume I (of 2) / Revised Edition

In Christendom, however, the chief application of these doctrines was to the relics of martyrs and saints. As with the amulets and talismans of Mesopotamia, these were regarded as possessing supernatural powers. They were a sure safeguard against evil spirits, and an unfailing relief in sickness.

Transmutation of metals—Alchemy.

A singular force was given to these mystic ideas by the peculiar direction they happened to take. As there are veins of water in the earth, and apertures through which the air can gain access, an analogy was inferred between its structure and that of an animal, leading to an inference of a similarity of functions. From this came the theory of the development of metals in its womb under the influence of the planets, the pregnant earth spontaneously producing gold and silver from baser things after a definite number of lunations. Already, however, in the doctrine of the transmutation of metals, it was perceived that to Nature the lapse of time is nothing—to man it is everything. To Nature, when she is transmuting a worthless into a better metal, what signify a thousand years? To man, half a century embraces the period of his intellectual activity. The aim of the cultivator of the sacred art should be to shorten the natural term; and, since we observe the influence of heat in hastening the ripening of fruits, may we not reasonably expect that duly regulated degrees of fire will answer the purpose? by an exposure of Philosopher's stone. base material in the furnace for a proper season, may we not anticipate the wished for event? The Emperor Caligula, who had formerly tried to make gold from orpiment by the force of fire, was only one of a thousand adepts pursuing a similar scheme. Some trusted to the addition of a material substance in aiding the fire to purge away the dross of the base body submitted to it. From this arose the doctrine of the powder of projection and the philosopher's stone.

Transmutation and transubstantiation.

This doctrine of the possibility of transmuting things into forms essentially different steadily made its way, leading, in the material direction, to alchemy, the art of making gold and silver out of baser metals, and in theology to transubstantiation. Transmutation and transubstantiation were twin sisters, destined for a world-wide celebrity; one became allied to the science of Mecca, the other to the theology of Rome.

The elixir of life.

While thus the Arabs joined in the pursuit of alchemy, their medical tendencies led them simultaneously to cultivate another ancient delusion, the discovery of a universal panacea or elixir which could cure all diseases and prolong life for ever. Mystical experimenters for centuries had been ransacking all nature, from the yellow flowers which are sacred to the sun, and gold his emblem and representative on earth, down to the vilest excrements of the human body. As to gold, there had been gathered round that metal many fictitious excellences in addition to its real values; it was believed that in some Potable gold. preparation of it would be found the elixir vitæ. This is the explanation of the unwearied attempts at making potable gold, for it was universally thought that if that metal could be obtained in a dissolved state, it would constitute the long-sought panacea. Nor did it seem impossible so to increase the power of water, as to impart to it new virtues, and thereby enable it to accomplish the desired solution. Were there not natural waters of very different properties? were there not some that could fortify the memory, others destroy it; some re-enforce the spirits, some impart dulness, and some, which were highly prized, that could secure a return of love? It had been long known that both natural and artificial waters can Chemical waters. permanently affect the health, and that instruments may be made to ascertain their qualities. Zosimus, the Panopolitan, had described in former times the operation of distillation, by which water may be purified; the Arabs called the apparatus for conducting that experiment an alembic. His treatise on the virtues and composition of waters was conveyed under the form of a dream, in which there flit before us fantastically white-haired priests sacrificing before the altar; cauldrons of boiling water, in which there are walking about men a span long; brazen-clad warriors in silence reading leaden books, and sphinxes with wings. In such incomprehensible fictions knowledge was purposely, and ignorance conveniently concealed.

The Arabs originate scientific chemistry.

The practical Arabs had not long been engaged in these fascinating but wild pursuits, when results of very great importance began to appear. In a scientific point of view, the discovery of the strong acids laid the true foundation of chemistry; in a political point of view, the invention of gunpowder revolutionized the world.
