The Testament of Hadrian

Why? Because all those imperfect things are full of impure diseases, and are therefore unworthy of the care of the mediators, since the virtue which is absent in their own parts is denied from elsewhere. Yet all power is in this one matter, whatever power the metals, the minerals, and vegetable nature hold—indeed, even that virtue by which the seven heavenly Dynasts the planetary spirits prevail—it excels and works wonderfully upon human limbs.

Behold for you, Offspring of Phoebus proles Phoebeja a poetic address to the alchemist as a child of the Sun/Apollo, our matter of the Etheric Stone Aetherei Lapidis. From now on, while you seek the same, make sure the tracks of the Green Lion viridis Leonis a common term for vitriol or a specific acidic solvent are known to you!

But once the matter is in your hands, having been identified and offered to you under the guidance of Jehovah Jova, learn what must be done next so that you may reach the desired goal of your prayer. The first wisdom is to discern the pure from the impure. Unless the matter is thoroughly purified, loosened from its thick limbs, and properly sublimated, it will not become a medium for tinting. Only the subtle parts, through which the spirit exits from the deepest bowels of nature, are able to exert these powers by penetrating bodies.

When this is perfected, wisely draw out two things contained within the purified matter: Salt Sal, distinguished by the philosophers under the name of Mercury Mercuriali; and then, under the form of an oil, the red Sulphur Sulphur rubicundum, which is full of weight. In the Salt, all secrets lie hidden: whoever knows how to dissolve this will penetrate into the innermost parts of the secret Temple. This is that White Eagle aquila alba purified sal ammoniac or sublimated mercury that is kin to the Red Lion Rubeo Leoni.
