Philosophers have laboured greatly in the art of ferments and of fermentations, which seems important above all others. With reference thereto some have made a vow to God and to the philosophers that they would never divulge its arcanum by similitudes or by parables.

Nevertheless, Hermes, the father of all philosophers, in the “Book of the Seven Treatises”, most clearly discloses the secret of ferments, saying that they consist only of their own paste; and more at length he says that the ferment whitens the confection, hinders combustion, altogether retards the flux of the tincture, consoles bodies, and amplifies unions. He says, also, that this is the key and the end of the work, concluding that the ferment is nothing but paste, as that of the sun is nothing but sun, and that of the moon nothing but moon. Others affirm that the ferment is the soul, and if this be not rightly prepared from the magistery, it effects nothing. Some zealots of this Art seek the Art in common sulphur, arsenic, tutia, auripigment, vitriol, etc., but in vain; since the substance which is sought is the same as that from which it has to be drawn forth. It should be remarked, therefore, that fermentations of this kind do not succeed according to the wishes of the zealots in the way they desire, but, as is clear from what has been said above, simply in the way of natural successes.

But, to come at length to the weight; this must be noted in two ways. The first is natural, the second artificial. The natural attains its result in the earth by Nature and concordance. Of this, Arnold says: If more or less earth than Nature requires be added, the soul is suffocated, and no result is perceived, nor any fixation. It is the same with the water. If more or less of this bc taken it will bring a corresponding loss. A superfluity renders the matter unduly moist, and a deficiency makes it too dry and too hard. If there be over much air present, it is too strongly impressed on the tincture; if there be too little, the body will turn out pallid. In the same way, if the fire be too strong, the matter is burnt up; if it be too slack, it has not the power of drying, nor of dissolving or heating the other elements. In these things elemental heat consists.

Artificial weight is quite occult. It is comprised in the magical art of ponderations. Between the spirit, soul, and body, say the philosophers, weight consists of Sulphur as the director of the work; for the soul strongly desires Sulphur, and necessarily observes it by reason of its weight.

You can understand it thus: Our matter is united to a red fixed Sulphur, to which a third part of the regimen has been entrusted, even to the ultimate degree, so that it may perfect to infinity the operation of the Stone, may remain therewith together with its fire, and may consist of a weight equal to the matter itself, in and through all, without variation of any degree. Therefore, after the matter has been adapted and mixed in its proportionate weight, it should be closely shut up with its seal in the vessel of the philosophers, and committed to the secret fire. In this the Philosophic Sun will rise and surge up, and will illuminate all things that have been looking for his light, expecting it with highest hope.

In these few words we will conclude the arcanum of the Stone, an arcanum which is in no way maimed or defective, for which we give God undying thanks. Now have we opened to you our treasure, which is not to be paid for by the riches of the whole world.


1 The work under this title is cited occasionally in other writings of Paracelsus, but is not included in the great folio published at Geneva in 1688. It was first issued at Basle in1575, and was accompanied with copious annotations in Latin by the editor, Gerard Dorne. This personage was a very persevering collector of the literary remains of Paracelsus, but is not altogether free from the suspicion of having elaborated his original. The Aurora is by some regarded as an instance in point; though no doubt in the main it is a genuine work of the Sage of Hohenheim, yet in some respects it does seem to approximate somewhat closely to previous schools of Alchemy, which can scarcely he regarded as representing the actual standpoint of Paracelsus.

2 He who created man the same also created science. What has man in any place without labour? When the mandate went forth: Thou shalt live by the sweat of thy brow, there was, as it were, a new creation. When God uttered His fiat the world was made. Art, however, was not then made, nor was the light of Nature. But when Adam was expelled from Paradise, God created for him the light of Nature when He bade him live by the work of his hands. In like manner, He created for Eve her special light when He said to her: In sorrow shalt thou bring forth children. Thus, and there, were these beings made human and earthy that were before like angelicals. … Thus, by the word were creatures made, and by this same word was also made the light which was necessary to man. … Hence the interior man followed from the second creation, after the expulsion from Paradise. … Before the Fall, that cognition which was requisite to man had not begun to develop in him. He received it from the angel when he was cast out of Paradise. … Man was made complete in the order of the body, but not in the order of the arts. – De Caducis, Par. III.

3 No work precisely corresponding co this title is extant among the writings of Paracelsus. The subjects to which reference is made are discussed in the Philosophia Sagax.

4 Before all things it is necessary to have a right understanding of the nature of Celestial Magic. It originates from divine virtue. There is that magic which Moses practised, and there is the maleficent magic of the sorcerers. There are, then, different kinds of Magi. So also there is what is called the Magic of Nature; there is the Celestial Magus; there is the Magus of Faith, that is, one whose faith makes him whole. There is, lastly, the Magus of Perdition. – Philosophia Sagax, Lib. II., c. 6.

5 Learn, therefore, Astronomic Magic, which otherwise I call cabalistic. – De Pestilitate, Tract I. This art, formerly called cabalistic, was in the beginning named caballa, and afterwards caballia. It is a species of magic. It was also, but falsely, called Gabanala, by one whose knowledge of the subject was profound. It was of an unknown Ethnic origin, and it passed subsequently to the Chaldaeans and Hebrews, by both of whom it was corrupted. – Philosophia Sagax, Lib. I., s. v. Probatio in Scientiam Nectromantricam.

6 The object which received the influence and exhibited the sign thereof appears to have been termed Gamaheu, Gamahey etc. But the name was chiefly given to certain stones on which various and wonderful images and figures of men and animals have been found naturally depicted, being no work of man, but the result of the providence and counsel of God. – De Imaginibus, c. 7 and c. 13. It is possible, magically, for a man to project his infiuence into these stones and some other substances. – Ibid., c. 13. But they also have their own inherent virtue, which is indicated by the shape and the special nature of the impression. – Ibid., c. 7. There was also an artificial Gamaheus invented and prepared by the Magi, and this seems to have been more powerful. – De Carduo Angelico.

7 Man was regarded by Paracelsus as himself in a special manner the true Quintessence. After God had created all the elements, stars, and every other created thing, and had disposed them according to His will, He proceeded, lastly, to the forming of man. He extracted the essence out of the four elements into one mass; He extracted also the essence of wisdom, art, and reason out of the stars, and this twofold essence He congested into one mass: which mass Scripture calls the slime of the earth. From that mass two bodies were made – the sidereal and the elementary. These, according to the light of Nature, are called the quintum esse. The mass was extracted, and therein the firmament and the elements were condensed. What was extracted from the four after this manner constituted a fifth. The Quintessence is the nucleus and the place of the essences and properties of all things in the universal world. All nature came into the hand of God – all potency, all property, all essence of the superior and inferior globe. All these had God joined in His hand, and from these He formed man according to His image. – Philosophia Sagax, Lib. I., c. 2.

8 All created things proceed from the coagulated, and after coagulation must go on to resolution. From resolution proceed all procreated things. – De Tartaro (fragment). All bodies of minerals are coagulated by salt. – De Natraralibus Aquis, Lib. III., Tract 2.

9 So acute is the potency of calcined blood, that if it be poured slowly on iron it produces in the first place a whiteness thereon, and then generates rust. – Scholia in Libros de Tartaro. In Lib. II., Tract II.

10 One recipe for the fixation of arsenic is as follows: – Take equal parts of arsenic and nitre. Place these in a tigillum, set upon coals so that they may begin to boil and to evaporate. Continue till ebullition and evaporation cease, and the substances shall have settled to the bottom of the vessel like fat melting in a frying-pan; then, for the space of an hour and a half (the longer the better), set it apart to settle. Subsequently pour the compound upon marble, and it will acquire a gold colour. In a damp place it will assume the consistency of a fatty fluid. – De Naturalibus Rebus, c. 9. Again: The fixation of arsenic is performed by salt of urine, after which it is converted by itself into an oil. – Chirurgia Minor, Lib. II.

11 Concerning the kinds of arsenic, it is to be noted that there are those which flow forth from their proper mineral or metal, and are called native arsenics. Next there are arsenics out of metals after their kind. Then there are those made by Art through transmutation. White or crystalline arsenic is the best for medicine Yellow and red arsenic are utilised by chemists for investigating the transmutation of metals, in which arsenic has a special efficacy. – De Naturalibus Rebus, c. 9.

12 The arcanum of vitriol is the oil of vitriol. Thus: after the aquosity has been removed in coction from vitriol, the spirit is elicited by the application of greater heat. The vitriol then comes over pure in the form of water. This water is combined with the caput mortuum left by the process, and on again separating in a balneum maris, the phlegmatic part passes off, and the oil, or the arcanum of vitriol, remains at the bottom of the vessel. – Ibid.

13 So long as the viridity or greenness of vitriol subsists therein, it is of a soft quality and substance. But if it be excocted so that it is deprived of its moisture, it is thereby changed into a hard stone from which even fire can be struck. When the moisture is evaporated from vitriol, the sulphur which it contains predominates over the salt, and the vitriol turns red. – De Pestilitate, Tract I.

14 The diagnosis of vitriol is concerned with it both in Medicine and Alchemy. In Medicine it is a paramount remedy. In Alchemy it has many additional purposes. The Art of Medicine and Alchemy consists in the preparation of vitriol, for it is worthless in its crude state. It is like unto wood, out of which it is possible to carve anything. Three kinds of oil are extracted from vitriol – a red oil, by distillation in a retort after an alchemistic method, and this is the most acid of all substances, and has also a corrosive quality – also a green and a white oil, distilled from crude vitriol by descension. – De Vitriolo. Nor let it be regarded as absurd that we assign such great virtues to vitriol, for therein resides, secret and hidden, a certain peculiar golden force, not corporeal but spiritual, which excellent and admirable virtue exists in greater potency and certainty therein than it does in gold. When this golden spirit of vitriol is volatilized and separated from its impurities, so that the essence alone remains, it is like unto potable gold. – De Morbis Amentium, Methodus II., c. 1.

15 Antimony can be made into a pap with the water of vitriol, and then purified by sal ammoniac, and in this manner there may be obtained from it a thick purple or reddish liquor. This is oil of antimony, and it has many virtues. – Chirurgia Magna, Lib. V. Take three pounds of antimony and as much of sal gemmae. Distil them together in a retort for three natural days, and so you will have a red oil, which has incredible healing power in cases of otherwise incurable wounds. – Chirurgia Minor, Tract II., c. 11.

16 Man himself was created from that which is termed limbus. This limbus contained the potency and nature of all creatures. Hence man himself is called the microcosmus, or world in miniature. – De Generatione Stultorum. Man was fashioned out of the limbus, and this limbus is the universal world. –Paramirum Aliud, Lib. II., c. 2. The limbus was the first matter of man. … Whosoever knows the limbus knows also what mam is. Whatsoever the limbus is, that also is man. – Paramirum Aliud, Lib. IV. There is a dual limbus, man, the lesser limbus, and that Great Limbus from which he was produced. – De Podagra, s. v. de Limbo. The limbus is the seed out of which all creatures are produced and grow, as the tree comes forth from its own special seed. The limbus has its ground in the word of God. – Ibid. The limbus of Adam was haven and earth, water and air. Therefore, man also remains in the limbus, and contains in himself heaven and earth, air and water, and these things he also himself is. – Paragranum Alterum, Tract II.
