Mercurius Quotes

Know this: I, Mercurius, have here set down a full, true and infallible account of the Great Work. But I give you fair warning that unless you seek the true philosophical gold and not the gold of the vulgar, unless you heart is fixed with unbending intent on the true Stone of the Philosophers, unless you are steadfast in your quest, abiding by God's laws in all faith and humility and eschewing all vanity, conceit, falsehood, intemperance, pride, lust and faint-heartedness, read no farther lest I prove fatal to you. For I am the watery venomous serpent who lies buried at the earth's centre; I am the fiery dragon who flies through the air. I am the one thing necessary for the whole Opus. I am the spirit of metals, the fire which does not burn, the water which does not wet the hands. If you find the way to slay me you will find the philosophical mercury of the wise, even the White Stone beloved of the Philosophers. If you find the way to raise me up again, you will find the philosophical sulphur, that is, the Red Stone and Elixir of Life. Obey me and I will be your servant; free me and I will be your friend. Enslave me and I am a dangerous enemy; command me and I will make you mad; give me life and you will die. ~ Patrick Harpur

When the alchemist speaks of Mercurius, on the face of it he means quicksilver (mercury), but inwardly he means the world-creating spirit concealed or imprisoned in matter. The dragon is probably the oldest pictoral symbol in alchemy of which we have documentary evidence. It appears as the Ouroboros, the tail-eater, in the Codex Marcianus, which dates from the tenth or eleventh century, together with the legend 'the One, the All'. Time and again the alchemists reiterate that the opus proceeds from the one and leads back to the one, that it is a sort of circle like a dragon biting its own tail. For this reason the opus was often called circulare (circular) or else rota (the wheel). Mercurius stands at the beginning and end of the work: he is the prima materia, the caput corvi, the nigredo; as dragon he devours himself and as dragon he dies, to rise again in the lapis. He is the play of colours in the cauda pavonis and the division into the four elements. He is the hermaphrodite that was in the beginning, that splits into the classical brother-sister duality and is reunited in the coniunctio, to appear once again at the end in the radiant form of the lumen novum, the stone. He is metallic yet liquid, matter yet spirit, cold yet fiery, poison and yet healing draught - a symbol uniting all the opposites. ~ C.G. Jung

On the 1st of August, 1774, I endeavoured to extract air from mercurius calcinates per se [mercury oxide]; and I presently found that, by means of this lens, air was expelled from it very readily. ... I admitted water to it [the extracted air], and found that it was not imbibed by it. But what surprized me more than I can well express, was, that a candle burned in this air with a remarkably vigorous flame ... I was utterly at a loss how to account for it. ~ J.B. Priestley
