Thanks for sharing everyone. Was reading more Fulcanelli and the VITRIOL image you shared Florius reminded me of this:
Fulcanelli: Dwellings of the Philosophers
As for the treatise of Azoth, it is a huge angel --- that of the parable of St John in the Book of Revelation --- who treads the earth with one foot and the sea with the other, while raising a burning torch with his right hand and compressing an air-inflated goatskin with the left one, clear images of the quaternary of the primal elements: earth, water, air, fire. The body of this angel, whose two wings replace the head, is covered by the seal of the open book, ornamented by the cabalistic star, and the seven words, emblem of Vitriol: Visita Interiora Terrae, Rectificandoque, Invenies Occultum Lapidem. "I then saw", writes St John, "another mighty angel come down from heaven, clothed with a cloud: and a rainbow was upon his head, and his face was, as it were, the sun, and his feet were as pillars of fire. He had in his hand a little open book, and he set his right foot upon the sea, and his left foot on the earth. And cried with a loud voice, as when a lion roareth; and when he had cried out, seven thunders uttered their voices. And when the seven thunders had resounded their voices, I was about to write; and I heard a voice from heaven saying unto me: Keep under seal the words of the seven thunders, and write them not... And the voice which I heard from heaven spake unto me again, and said: Go and take the little open book which is in the hand of the angel who standeth upon the sea and upon the earth. And he said unto me: Take it and eat it; it shall make thy belly bitter, but it shall be in thy mouth sweet as honey".
