"Even as the dragon represents the one that separated self so far as to fight with, to destroy with, those that would make of themselves a kingdom of their own." [Cayce 281-16] [See Narcissist]

Nicholas Barnaud Delphinas
This surely is a great miracle and without any deception—that in a venomous dragon there should be the great medicine:
The Mercury is precipitated or sublimed, dissolved in its own proper water, and then once more coagulated.
A savage Dragon lives in the forest,
Most venomous he is, yet lacking nothing:
When he sees the rays of the Sun and its bright fire,
He scatters abroad his poison,
And flies upward so fiercely
That no living creature can stand before him,
Nor is even the Basilisk equal to him.
He who hath skill to slay him, wisely
Hath escaped from all dangers.
Yet all venom, and colours, are multiplied
In the hour of his death.
His venom becomes the great Medicine.
He quickly consumes his venom,
For he devours his poisonous tail.
All this is performed on his own body,
From which flows forth glorious Balm,
With all its miraculous virtues.
Here at all the Sages do loudly rejoice. [Book Of Lambspring, by Nicholas Barnaud Delphinas (Musaeum Hermeticum Reformatum et Amplificatum, c. 1678) ]
John de Monte Snyders
"The Philosophers have compared this matter to a three headed Dragon for two reasons: First because by the mediation of this matter all metallick bodies may, yea and must be brought to their first matter, namely into Mercury, Sulphur and Salt. Secondly because in the preparation and decoction of the Stone three chief or principal colours, viz, black, white and red, are found. With these colours I say they have adorned the three heads of the crawling dragon. It is the universal matter and to be found all the world over. For the world without ceasing produceth such a primum Ens or double nature, whereby the Philosophers have obtained health and riches." [The Metamorphosis of the Planets by John de Monte Snyders]
Basil Valentine
"I am the dragon, venomous, present everywhere, and to be obtained at the smallest price. Upon that which rests above me do I rely, and whoever investigates me within myself shall discover the truth. My water and fire destroy, and by compounding them you will extract from my body the green and the red lion. If you do not know me precisely, you will abuse my fire with your five senses.
A scorching venom emerges from my nostrils, which has brought ruin to many. Therefore, carefully separate the coarse from the subtle, and you will rejoice in extreme wealth. I generously bestow upon you the riches of the heavens and the earth, equally for men and women. But the mysteries of my soul must be handled courageously and magnanimously. If you desire to operate in this work, which involves many labors and much wealth, you must subject yourself to the fire of my soul.
I am the egg of nature, known to the wise by the sun alone, who have generated from me the pious and modest microcosm. It is prepared by the divine will of the Supreme God, yet granted to very few, even though many fruitlessly desire it. It has been given that the poor may be enriched by my treasure, but let them not fix their souls on perishable gold. I am called Mercury by the philosophers, my spouse is gold (the Philosophical Stone).
I am the ancient dragon, present everywhere on the earth, father, mother, youth, and elder. I am the strongest and most subtle, visible and invisible, hard and soft, mortal and rejuvenating. I descend to the earth and ascend to the heavens, the highest and the lowest, the heaviest and the lightest. In the natural order, I am often found in color, number, weight, and measure, containing natural light, both obscure and luminous. Emerging from the earth, I am known and am as though nothing at all, and yet I bring forth all colors to shine, and metals are perfected through the rays of the sun: the solar carbuncle, the most noble earthly matter, by which copper, iron, tin, and lead are transmuted into gold." [Azoth, sive aureliae occcultae philosophorum, c. 1613 by Basil Valentine]
Fulcanelli
"The alchemists are alluding to this operation, when they speak of reanimating the corporifications, that is to say giving life to the dead metals. It is Philalethes’ Entrance to the Closed Palace of the King and Ripley’s and Basil Valentine’s first door, which one must know how to open. The old man is none other than our Mercury, the secret agent, whose nature, method of action, materials and time of preparation have been revealed to us in several bas-reliefs.
As for the Palace, it represents the living, philosophic or base gold, despised by the ignorant and hidden under the rags, which conceal it from our eyes, although it is extremely precious to one who knows its value. In this motif, we see a variation of the allegory of the green and red lions, of the solvent and the body to be dissolved. Indeed the old man, whom the texts indentify with Saturn—who, it is said, ate his children—was formerly painted green, while the interior of the palace showed a purple colouring.
I shall say later to what source one may refer, in order to re-establish the meaning of all these figures, by means of the original colours. It should also be noted that the hieroglyph of Saturn, considered as a solvent, is very ancient. On a sarcophagus at the Louvre, which had contained the mummy of a hierophant priest of Thebes named Poeris, the god Shu can be seen on the left hand side, holding up the sky, with the aid of the god Chnouphis (the soul of the world), while at their feet crouches the god Ser (Saturn), whose skin is green in colour." [The Mystery of Cathedrals, c. 1926 by Fulcanelli]
Basil Valentine
"I am a poisonous dragon, present everywhere, and to be had for nothing. My water and my fire dissolve and compound; out of my body thou shall draw the green and red lion; but if thou dost not exactly know me, thou wilt with my fire destroy thy five senses. A most pernicious quick-poison comes out of my nostrils, which hath been the destruction of many.
Separate, therefore, the thick from the thin artificially, unless thou dost delight in extreme poverty. I give thee faculties both male and female, and the powers both of heaven and earth.
The mysteries of my art are to be performed magnanimously and with great courage, if thou wouldst have me overcome the violence of the fire, in which attempt many have lost their labour and their substance. I am the Egg of nature, known only to the Wise, such as are pious and modest, who make of me a little world." [Azoth, sive aureliae occcultae philosophorum, c. 1613 by Basil Valentine]

Nicolas Flamel
"The potentiality of mercury, which is the metallic fire: being thus united, it is called by the philosophers the flying dragon; because the dragon kindled by its fire, while he flies by little and little, fills the air with his fire, and poisonous vapours.
The same thing doth mercury; for being placed upon an exterior fire, and in its place in a vessel; it sets on fire its inside, which is hidden in its profundity; by which may be seen, how the external fire does burn and inflame the natural mercury. And then you may see how the poisonous vapour breaks out into the air, with a most stinking and pernicious poison; which is nothing else but the head of the dragon, which hastily goes out of Babylon.
But other philosophers have compared this mercury, with a flying lion, because a lion is a devourer of other creatures, and delights himself in his voracity of every thing, except that which is able to resist his violence and fury. So also does mercury, which has in itself such a power, force, and operation, to spoil and devastate a metal of its form, and to devour it. Mercury being too much influenced, devours and hides metals in its belly; but which of them so ever it be, it is certain, that, it consumes it not, for in their nature they are perfect, and much more indurate.
But mercury has in itself a substance of perfecting sol and luna; and all the imperfect bodies or metals, proceed from argent vive; therefore the ancients called it the mother of metals; whence it follows, that in its own principle and centre, being formed, it has a double metallic substance. And first, the substance of the interior; then the substance of sol, which is not like the other metals; of these two substances, argent vive is formed, which in its body is spiritually nourished.
As soon then as nature has formed argent vive, of the two after-named spirits, then it endeavors to make them perfect and corporeal; but when the spirits are of strength, and the two sperms awakened out of their central principle, then they desire to assume their own bodies. Which being done, argent vive the mother must die, and being thus naturally mortified, cannot (as dead things cannot) quicken itself as before.
But there are some proud philosophers, who in obscure words affirm, that we ought to transmute both perfect and imperfect bodies into running argent vive; this is the serpent's subtlety, and you may be in danger of being bit by it. It is true, that argent vive may transmute an imperfect body, as lead or tin; and may without much labour, multiply in a quantity; but thereby it diminishes or loses its own perfection, and may no more for this reason be called argent vive.
But if by art it may be mortified, that it can no more vivify itself, then it will be changed into another thing, as in cinnabar, or sublimate is done. For when it is by the art coagulated, whether sooner or later, yet then its two bodies assume not a fixed body, nor can they conserve it, as we may see in the bowels of the earth."
