"The dragon devours its wings and emits a variety of colors, shifting from one to another until it finally turns white. This creature is extremely self-sufficient — it should not be fed unless it experiences thirst or hunger; know that if it goes three days without food, it will perish. Thus is the Dragon born. The son of the dead will live, the king will come from fire, and they will rejoice in their union; eyes will appear, and the maiden’s womb will be whitened. Our son has already been tempered by fire, and the warrior surpasses all." —"Donum Dei", Recueil, Georges Aurach, 1601-1700, Bibliothèque nationale de France

"The Dragon shuns the sunbeams which dart through the crevices, and our dead son lives; king comes forth from the fire and rejoins with his spouse, the occult treasures are laid open, and the virgin's milk is whitened. The Son, already vivified is become a warrior in the fire and of tincture super-excellent. For this Son is himself the treasury, even himself bearing the Philosophic Matter. Approach, ye Sons of Wisdom, and rejoice; let us now rejoice together, for the reign of death is finished, and the Son doth rule. And now he is invested with the red garment, and the scarlet colour is put on." — The Golden Tractate of Hermes Trismegistus

"This our stone is fire, created of fire, and turns into fire; its soul dwells in fire."
- Rosarium Philosophorum
"So, in the Art, you can have no success if you do not in the first work purify the Serpent, born of the Slime of the earth; it you do not whiten these foul and black faeces, to separate from thence the white sulphur, which is the Sal Amoniac of the Wise, and their Chaste Diana, who washes herself in the bath; and all this mystery is but the extraction of the fixed salt of our compound, in which the whole energy of our Mercury consists."
"Likewise this our stone, i.e., the flask of fire, is created out of fire and turns back into it"

"For until the Infant, that is, this our stone, be formed and leavened with its like, the Bloud of the green Dragon, and the red Bloud of the Red Dragon, whether it be the white Stone or the red, it will never do a perfect work. Know therefore, Son, that the first Water is that Water Rebar, which God made of Nature, and it is the cause of Generation, as I said before; but when after the conjunction which ariseth from the Marriage, it begets the Water of Life, and the Philosophers Milk, with one of which, or both, you must augment and feed your Stone perpetually."
- George Ripley, Treatise of Mercury and the Philosophers’ Stone
"Mark thou now in thy mind
Acetome of philosophers men call this
A water abiding so it is
The maidens milk of the dew
That all the work doth renew
The S erpent of life it is called also
And other names many more
The which causeth generation
Betwixt the man and the woman
But looke thou no division
Be there in the conjunction
Of the moon and of sun
After the marriage be begun"
- The Ripley Scroll
"Under the Altar lyes the Green Dragon or the Magician's Mercury involving in it self a Treasure of Gold and Pearl."
