That problematic medium, which was to serve to tincture or transmute the baser metal or its mercury to silver or gold, was called the Philosopher's stone. It had the power to make the sick (base) metal well (precious). Here came in the idea of a universal medicine. Alchemy desired indeed to produce in the Philosopher's Stone a panacea that should free mankind of all sufferings and make men young.

It will not be superfluous to mention here, that the so-called materials, substances, concepts, are found employed in the treatises of the alchemists in [pg 115] a more comprehensive sense, we can even say with more lofty implications, the more the author in question leans to philosophical speculation. The authors who indulged the loftiest flights were indeed most treasured by the alchemists and prized as the greatest masters. With them the concept mercury, as element concept, is actually separated from that of common quicksilver. On this level of speculation, quicksilver (Hg.) is no longer considered as a primal element, but as a suprasensible principle to which only the name of quicksilver, mercury, is loaned. It is emphasized that the mercurius philosophorum may not be substituted for common quicksilver. Similar transmutations are effected by the concept of a primal element specially separated from mercury. Prima materia is the cause of all objects. Also the material from which the philosopher's stone is produced is in later times called the prima materia, accordingly in a certain sense, the raw material (materia cruda) for its production. But I anticipate; this belongs properly to the occidental flourishing period of the alchemy of scholasticism.

A very significant and ancient idea in alchemy is that of sprouting and procreation. Metals grow like plants, and reproduce like animals. We are assured by the adepts (those who had found it, viz., the panacea) in the Greek-Egyptian period and also later, that gold begets gold as the corn does corn, and man, man. The practice connected with this idea consists in putting some gold in the mixture that is to be transmuted. The gold dissolves like a seed [pg 116] in it and is to produce the fruit, gold. The gold ingredient was also conceived as a ferment, which permeates the whole mixture like a leaven, and, as it were, made it ferment into gold. Furthermore, the tincturing matter was conceived as male and the matter to be colored as female. Keeping in view the symbol of the corn and seed, we see that the matter into which the seed was put becomes earth and mother, in which it will germinate in order to come to fruition.

In this connection belongs also the ancient alchemic symbol of the philosopher's egg. This symbol is compared to the “Egyptian stone,” and the dragon, which bites its tail; consequently the procreation symbol is compared to an eternity or cycle symbol. The “Egyptian stone” is, however, the philosopher's stone or, by metonomy, the great work (magnum opus) of its manufacture. The egg is the World Egg that recurs in so many world cosmogonies. The grand mastery refers usually and mainly to thoughts of world creation. The egg-shaped receptacle in which the master work was to be accomplished was also known as the “philosophical egg” in which the great masterpiece is produced. This vessel was sealed with the magic seal of Hermes; therefore hermetically sealed.

A wider theoretical conception, originating with the Arabs, is the doctrine of the two principles. They were retained in the subsequent developments and further expanded. Ibn Sina [Avicenna, 980-ca. 1037] taught that every metal consisted of mercury [pg 117] and sulphur. Naturally they do not refer to the ordinary quicksilver and ordinary sulphur.

From the Arabs alchemy came to the occident and spread extraordinarily. Among prominent authors the following may be selected: Roger Bacon, Albertus Magnus, Vincent of Beauvais, Arnold of Villanova, Thomas Aquinas, Raymond Lully, etc.

The amount of material that could be adduced is enormous. It is not necessary, however, to consider it. What I have stated about the beginnings of alchemy is sufficient in amount to enable the reader to understand the following exposition of the alchemic content of the parable. And what I must supply in addition to the alchemic theories of the time of their prevalence in the west, the reader will learn incidentally from the following analysis.

In concluding this preliminary view I must still mention one novelty that Paracelsus (1493-1541) introduced into the theory. Ibn Sina had taught that two principles entered into the constitution of metals. Mercury is the bearer of the metallic property and sulphur has the nature of the combustible and is the cause of the transmutation of metals in fire. The doctrine of the two principles leads to the theory that for the production of gold it was necessary to get from metals the purest possible sulphur and mercury, in order to produce gold by the union of both. Paracelsus now adds to the two principles a third, salt, as the element of fixedness or palpability, as he terms it. According to my notion, Paracelsus has not introduced an essential innovation, but only used [pg 118] in a new systematic terminology what others said before him, even if they did not follow it out so consistently. The principles mercury, sulphur and salt—their symbols are [Symbol: Mercury], [Symbol: Sulphur] and [Symbol: Salt]—were among the followers of the alchemists very widely used in their technical language. They were frequently also called spirit, soul and body. They were taken in threes but also as before in twos, according to the exigencies of the symbolism.

The alchemists' usual coupling of the planets with metals is probably due to the Babylonians. I reproduce these correspondences here in the form they generally had in alchemy. I must beg the reader to impress them upon his memory, as alchemy generally speaks of the metals by their planetary names. According to the ancient view (even if not the most ancient) there are seven planets (among which was the sun) and seven metals.
