The Theatre of Terrestrial Astronomy. This is ascribed to Edward Kelly and included in Tractatus duo egregii, de Lapide Philosophorum, c. 1676
"On the preparation of Mercurial Earth It is proper to know that from all perfected metals a medicine can be made, which can also transmute the remaining metals into gold and silver. Furthermore, from the perfected metals, by the separation of the required elements—Salt of Nature, or the Philosophers' Vitriol, which some call the Philosophers' Lime—through the industry of the artist, the Philosophical Work is accomplished. Without this, the Philosophical Work cannot be brought to its end. For the art presupposes a thing created by nature alone, in which lies the aid of nature itself, and of this art. A glass vessel stood in a circle of crimson color. Within it were Mercury, Mars, and Saturn, who lay on their backs. The Old Man was about to inject Venus and Jupiter. After the Old Man, on the black cliff, stood the Moon and the Sun amid smoke."
