This primal substance has seen its evolution interrupted by the interposition and penetration of a filthy combustible sulphur, which coats its pure mercury, holds it back, and coagulates it. And, though it is entirely volatile, this primitive mercurius , materialized by the drying action of the arsenical sulphur, takes the shape of a solid, black, dense, fibrous, brittle, crushable mass rendered, by its lack of utility, vile, abject, and despicable in the eyes of man. Yet, in this subject ~ poor relative of the metal family ~ the enlightened artist finds everything that he needs to begin and perfect his Great Work, since it is present, say the authors, at the beginning, the middle, and the end of the Work. ……. our subject contains a frightful poison whose very odor would suffice to cause death. Yet it is from this toxic mineral that the universal medicine is made, which no human illness can resist, no matter how incurable it is thought to be. But that which gives it all its value and makes it infinitely precious in the eyes of the sage is the admirable virtue it possesses, of revivifying metals that have been reduced and molten and of losing its poisonous properties by granting them its own activity. And so it does appear to be the instrument of resurrection, and of redemption of the metallic bodies, dead by violence of a reducing fire, the reason for which it bears in its coat of arms, the sign of the Redeemer, the cross.”
