Comments by alchemists on the Stone which turns all things to gold:

From a man and a woman make a circle, then a square, then a triangle, finally a circle, and you will obtain the Philosopher's Stone.
- Michael Maier

But when we marry the crowned king with the red daughter, she will conceive a son in the gentle fire, and shall nourish him through our fire... Then is he transformed, and his tincture (tinge of colour) remains red as flesh. Our son of royal birth takes his tincture from the fire, and death, darkness and the waters flee away. The dragon shuns the light of the sun, and our dead son shall live. The king comes forth from the fire and rejoices in the marriage.
- Tractatus aureus

Take the serpent and place it in the chariot with four wheels and let it be turned about on the earth until it is immersed in the depths of the sea, and nothing more is visible but the blackest Dead Sea... and when the vapour is precipitated like rain... you should bring the chariot from water to dry land, and then you have placed the four wheels on the chariot, and will obtain the result if you will advance further to the Red Sea, running without running, moving without motion.
- Tractatus Aristotelis as Alexandrum Magnum

Out of other things thou will never make the One, until thou hast first become One thyself.
- Gerhard Dorn
