Philosopher’s Stone Part Seven:
Clavicula (Little Key of Llull) — The True Argent Vive and Its Multiplication
Bibliographic Introduction
The Clavicula, or Little Key of Llull, is a short pseudoepigraphic treatise from the 14th century, attributed to Ramon Llull but almost certainly composed by a later alchemist. It is positioned as a companion to the Testamentum, declaring that without this “little key,” the rest of Llull’s alchemical corpus cannot be understood. Though brief, it serves as a clear catechism of central doctrines: the rejection of vulgar mercury, the necessity of argent vive extracted from Sol and Luna, and the stages of color transformation leading to multiplication of the Stone.
Philosophical Mercury in the Clavicula
The text insists on a strict distinction between vulgar quicksilver and the true argent vive of the philosophers:
“Argent vive Vulgar cannot be the Argent vive of the Philosophers, whatever Art it be prepared with, for the Vulgar cannot be detained in the Fire, but by another Argent vive corporeal which is hot and dry, and more digested.” (Clavicula, Ch. 1)
This true mercury is described as hot, dry, corporeal, and fixed, in contrast to the cold and moist vulgar mercury. It is extracted from Sol and Luna themselves, not from mines or apothecaries’ shops:
“Unless you take the Argent vive of these two [Sol and Luna], you go on to the Practick as blind men without eyes and sense.” (Clavicula, Prologue)
Philosophical mercury here is defined as a metallic essence, a humidity concealed within gold and silver, drawn out through art, capable of union with vulgar mercury to render it stable and medicinal.
Extracting the Method
The Clavicula gives more operational detail than the Testamentum. Its method includes:
-
Reduction of Bodies: Sol and Luna must be reduced into their first matter, their hidden argent vive.
-
Amalgamation: Vulgar mercury is united with this extracted mercury, which dries its cold humidity and fixes it.
-
Putrefaction: The mixture blackens like coal — the “eclipse” of Luna and Sol.
-
Color Progression: Black → grey-brown → white → red.
-
Calx viva: A quick slime or white powder is formed, the “mine” of the philosophers.
-
Multiplication: This powder can be projected infinitely, multiplying silver or gold beyond natural ore.
The text includes recipes: calcination of Luna on porphyry, imbibition with oil of tartar, extraction of mercury by corrosive “stinking menstruals” of vitriol and saltpeter, and sublimation with alembics. These details show that the author was acquainted with laboratory practice, though expressed in allegorical terms.
Evidence of Practice
Unlike Arnaldus or the Epistle genre, the Clavicula uses specific procedures: rectifying corrosive menstrua, drying calxes, stirring precipitates with boiling water, observing the precipitation of metallic mercury. Such imagery suggests contact with actual metallurgical operations. While the recipes are not straightforwardly workable, they reflect an operator’s memory of chemical manipulations, cloaked in allegory.
Contribution to the Stone Tradition
The Clavicula makes several key contributions:
-
Explicit Rejection of Vulgar Mercury: Only mercury extracted from Sol and Luna counts.
-
Doctrinal Clarity: Argent vive is hot, dry, fixed — the opposite of vulgar quicksilver.
-
Multiplication Doctrine: Once true mercury is prepared, its powder can multiply infinitely.
-
Operational Detail: Provides a clearer laboratory sequence than the Testamentum.
In contrast to the Testamentum’s broader allegory, the Clavicula attempts to present a direct manual, though still couched in secrecy.
Deciphered Method
Summarized, the Clavicula’s method is:
-
Calcine Luna or Sol, grind on porphyry, imbibe with philosophical solvents.
-
Extract argent vive from the calx using a rectified corrosive menstrual.
-
Unite this true mercury with vulgar mercury by amalgamation.
-
Putrefy under gentle fire, observe blackening and subsequent whitening.
-
Obtain calx viva (white powder), capable of reducing vulgar mercury into true metals.
-
Multiply the powder infinitely, projecting into molten silver or gold.
Philosophical mercury here is the argent vive extracted from Sol and Luna, hot, dry, fixed, and medicinal.
Conclusion
The Clavicula or Little Key of Llull crystallizes the pseudo-Llullian doctrine: the philosophers’ mercury is not vulgar quicksilver, but a fixed metallic humidity drawn from Sol and Luna themselves. Its method emphasizes amalgamation, color stages, and multiplication, giving more practical imagery than the Testamentum. Though brief, it served as a catechism for later adepts, reinforcing the definition of true mercury and warning against the errors of vulgar interpretation.
