Three derivations are offered of the name Rosicrucian. The first, which is certainly the most obvious, deduces it from the ostensible founder of the order, Christian Rosenkreuze. I shall show, however, that the history of this personage is evidently mythical or allegorical, and therefore this explanation merely cakes the inquiry a step backward to the question, What is the etymology of Rosenkreuze? The second derivation proposed is from the Latin words Ros , dew, and Crux , cross. This has been countenanced by Mosheim, who is followed by Ree's Encyclopædia; and other publications. The argument in its favour may be fairly represented by the following quotation:--"Of all natural bodies, dew was deemed the most powerful dissolvent of gold; and the cross, in chemical language, was equivalent to light; because the figure of a cross exhibits at the same time the three letters of which the word lux, or light, is compounded. Now, lux is called . . . the seed or menstruum of the red dragon, or, in other words, that gross and corporeal light, which, when properly digested and modified, produces gold. Hence it follows, if this etymology be admitted, that a Rosycrucian philosopher is one who by the intervention and assistance of the dew, seeks for light, or, in other words, the substance called the Philosopher's Stone."
This opinion exaggerates the importance attributed to the dew of the alchemists. The universal dissolvent has figured under various names, of which ros is by no means most general; the comprehensive "Lexicon Alchymiæ" does not mention it. According to Gaston le Doux, in his "Dictionnaire Hermétique," Dew, simply so called, signifies Mercury; Dew of the Philosophers is the matter of the stone when under the manipulation of the artist, and chiefly during its circulations in the philosophical egg. The White and Celestial Dew of the Wise is the philosophical stone perfected to the White. Mosheim derived his opinion from Peter Gassendi, 2 and from a writer in Eusebius Renandot's "Conferences Publiques," 3 who confesses that he knew nothing whatsoever of the Rosicrucians till the task of speaking on the subject was imposed on him by the Bureau d’Addresse . He says:--"Dew, the most powerful dissolvent of gold which is to be found among natural and non-corrosive substances, is nothing else but light coagulated and rendered corporeal; when it is artistically concocted and digested in its own vessel during a suitable period it is the true menstruum of the Red Dragon, i.e. , of gold, the true matter of the Philosophers. The society desiring to bequeath to posterity the ineffaceable sign of this secret, caused them to adopt the name Frères de la Rozée Cuite ." The mystic triad of the Society, F. R. C., has been accordingly interpreted Fratres Roris Cocti , the Brotherhood of the Concocted or Exalted Dew, but the explanation has little probability in itself.
"Several chemists," says Pernetz, in his "Dictionnaire Mytho-Hermétique," "have regarded the dew of May and September as the matter of the Magnum Opus , influenced doubtless by the opinion of various authors that dew was the reservoir of the universal spirit of Nature. . . . But when we seriously study the texts of the true philosophers, wherein they snake reference to dew, we are soon convinced that they only speak of it by a similitude, and that theirs is metallic, that is, it is the mercurial water sublimated into vapour within the vase, and precipitated at the bottom in the form of fine rain. Thus when they write of the dew of the month of May, they are referring to that of their philosophic Spring, which is governed by the gemini of the alchemical Zodiack, which differs from the ordinary astronomical Zodiack. Philalethes has positively said that their dew is their mercurial water rising from putrefaction."
