JOHANNES DE RUPECISSA.
This writer is considered one of the most remarkable of the Hermetic philosophers. He abounds with prophetic passages, and denounces the fate of nations, but in his alchemical explanation of things physical is obscure even for an adept. Nothing is known of his life,[R] beyond the nobility of his origin and his imprisonment in 1357, by Pope Innocent VI., whom he had reprehended. The illustrious Montfauçon was one of his descendants, and he poses as an initiate of the secret chemistry in the following works:—“The Book of Light,” “The Five Essences,” Cœlum Philosophorum, and his most celebrated treatise De Confectione Lapidis. There he declares that the matter of the philosophical stone is a viscous water which is to be found everywhere, but if the stone itself should be openly named, the whole world would be revolutionised. The divine science possessed by the wise is somewhat poetically celebrated as an incomparable treasure. Its initiates are enriched with an infinite wealth beyond all the kings of the earth; they are just before God and men, and in enjoyment of the special favour of Heaven.
