At a Glance

The wordMercury names the messenger god and a philosophical material whose motion, penetration and relation to sulfur are pictured by the caduceus. The two serpents make reciprocal action visible.
In the manuscriptA winged young man, a striking wand and mutually devouring serpents express sublimation, dissolution, coagulation and the first operations. Later Mercury steals other gods’ attributes and carries tinctures and souls.
TranslationCapitalized Mercury usually preserves the personified figure; mercury and quicksilver serve the material exposition. The surrounding gloss, rather than capitalization alone, determines the referent.
A place to readManuscript 10v–11r, scans 36–37: the two serpents and the wand receive a direct account of sulfur’s and mercury’s opposed powers.

Meaning

The caduceus is a relation drawn as an instrument. Its winding serpents do not merely accompany a god: one power dissolves what another fixes. Mercury's cold moisture makes sulfur raw again; sulfur's hot fixity holds, imprisons and coagulates mercurial water. Each can be called the other's death. Their mutual violence therefore gives a shape to the change of state through which the work proceeds.

The young man and the material also share one grammatical life. Mercury descends, steals, hides things in his belly and is imprisoned; mercury becomes vapor, incorporates sulfurous vapors, grows heavy and fixes as metal. The narrative is continually translated into operations. A reader must attend to the change of register without assuming that every mythic action conceals an additional unmentioned ingredient.

Mercury's name is broader here than ordinary running quicksilver. The source explicitly names running quicksilver at 33v, but also describes prepared mercurial water, spirits, a medium of tinctures and a governing planetary power. Those local descriptions distinguish senses within the manuscript's vocabulary. The entry on quicksilver treats the material name more directly.

Use in the book

The first model at 6v–7r shows a young man in a cloud, wearing iron armor and wings at his heels, striking his helmet with a serpent-entwined caduceus. The threatening old figure introduces time and Saturn. At 8r, scan 31, another wand bears serpents twisting to devour each other and a winged helmet above. The repetition makes the instrument an organizing figure of the represented book, not an incidental attribute.

At 8v, scan 32, winged equipment signifies a dissolving power and subtlety more vaporous than other waters. At 10r the striking of the helmet becomes a rule for reading poetry: striking means corrupting and resolving into moisture. The next page gathers the weapons of several heroes under that action, then explains the serpents as cold mercurial moisture and hot fixing sulfur. The visible combat supplies the polarity required to understand the changing subject.

At 11r, scan 37, Vulcan's imprisonment of Mercury is placed beside water's penetration of bodies. Mercury's wand is then compared with Moses's rod, the devouring serpent, water from rock and oil from stone. The author says the serpents show the first principles and first operations. He is asserting continuity between different image traditions through a shared physical power, while retaining their recognizable objects.²⁰⁰

The sustained mythographic exposition at 32r–34v begins with Mercury's mother, whom the author calls matter. His thefts include Apollo's cattle, Neptune's trident, Mars's sword, Vulcan's tongs and Venus's girdle. At 33v the hidden cattle become sulfurous vapors that enrich quicksilver after a slight heat makes it spirit. At 34r the stolen objects receive cutting, dissolving and germinative meanings. Vulcan's tongs are a hot instrument of nature; Jupiter's thunderbolt remains beyond a Mercury too swollen with terrestrial fire to receive its impression.

Argus's death at 34v means the mortification of shining quicksilver, whose brightness resembles an eye or mirror. The cock represents inward sulfur's power to coagulate moisture. Later, at 39r, scan 103, the mercurial medium is a carrier of tinctures and souls, and three pairs of soldiers distinguish killing, receiving and carrying. At 102r, scan 237, Mercury's doubtful, amphibious nature enters the warning against indiscriminate material marriages. The messenger's capacity to connect things does not remove the requirement to recognize and separate their natures.

Translation

The edition retains Mercury's personification rather than replacing every appearance with a single substance-name. Caducée is caduceus, baguette wand, and verge rod in the Moses comparison. Se météorise is translated through becoming a meteor and immediately becoming spirit, following the author's own gloss.

At 34r the source cancels céleste and leaves terrestre in the description of Mercury's obstructive fire. The English accordingly says terrestrial, and the French discloses the cancellation. That correction matters: the failed theft of Jupiter's power is explained by a fire too dense and earthly, not by an excess of the very celestial impression sought.²⁰¹

caducée

Attested: H001-S026b; H001-S036; H001-S088. The serpent-entwined instrument and a general emblem of dissolving action.

baguette de Mercure

Attested: H001-S036; H001-S037. The wand whose serpents show first principles and operations.

se météorise

Attested: H001-S090; H001-S091. Becomes a meteor or spirit; the source explains the term through release from bodily bonds.

voiturier des teintures et des âmes

Attested: H001-S103. The carrying function of the mercurial medium.

Source note

The Moses comparison is the manuscript’s own interpretive juxtaposition at scan 37. It collects the devouring staff-serpent, water and oil imagery in one account; the lexicon does not infer a historically identical origin for the images.

Scan 91 visibly cancels céleste before terrestre. The edition follows the uncancelled word and records the rejected reading in the source transcription.
