Meaning

Dialogue. The dream vocabulary distinguishes sleep, an appearing vision, a dream used as instruction, and a phantom generated by intense imagination. These are not automatically equivalent categories of revelation.

Treatise of Sulphur. Somnium and visio frame the narrative as dream and vision. Diana, the prince, Saturn and speaking souls are dramatis personae; candelulae are the ordinary sulphur fire-lighters that puncture the alchemist’s expectations.

Use in the book

Dialogue. The first sleeping vision introduces an old man who asks which Mercury the worker intends to use. He grants that Mercury is one but varies by place and purity, then denies that the alchemist’s ordinary purification is the wise men’s true purification. On waking, the worker cannot conceive any other subject and tries to summon the encounter again by pretending to sleep. The comedy tests his response to counsel, not merely the presence of a dream.

The next appearance is explicitly introduced as a phantom arising from forceful imagination after exhausting labour and loss of property. It confirms that his present material is good and suggests conjuring Mercury like a serpent. The worker’s relief and the ensuing speech of Mercury must not erase the narrator’s explanation of this apparition. Advice that flatters his existing project belongs to a different narrative framing from the first corrective vision.

Finally he cites recently revealed dreams as evidence that he will certainly make the stone and calls upon his wife to confirm his habit of true dreams. This is his claim under rebuke, not the narrator’s general theory that dreams certify knowledge. The distinction is useful when comparing this dialogue with other dreamlike narratives in the corpus.

Treatise of Sulphur. The learned but misguided alchemist enters Venus’s grove, where ores, animals, plants and specially drawn waters coexist. Saturn’s explanations do not cure his impatience or literal-mindedness. In a dream Salt wounds Sulphur; Diana bathes in the resulting milky river; a prince tries to save her and both drown. Their souls declare themselves freed from stained bodies but promise return only after purification.

The alchemist then collects the dead sulphur and refuses mercury. Repeated work produces only matches. Saturn’s contrasting dream performance succeeds with two quicksilvers of one root, but the dancing alchemist drops the vessel and awakens with only his matches. The volatile stone and kidney-stone joke expose the gap between seeing, boasting and understanding. The narrative cannot safely be treated as a transparent laboratory protocol.

Translation in this edition

Dialogue. The edition retains visio, phantasma and somnium in distinct narrative contexts. No clinical diagnosis is inferred from the historical vocabulary of delirium or imagination.

Treatise of Sulphur. The translation identifies candelulae as little sulphur matches, not the desired stone. Irony belongs especially to Saturn’s praise and the alchemist’s confident self-description.
