John Rudolph Glauber, The works of the highly experienced and famous chymist… (1689)
“ In the Creation of the World salt was first made, from which afterwards the four Elements proceeded, so that by the Philosophers salt is called The Center of the Elements concentrated; and by the same reason, by which it was the first, it still is, and remaineth the last. All things arise from salt, and after they are destroyed by death, do again return into the same. Et sal thesauros grandes & possidet ignis. In Salt and Fire are contained great Treasures. Salt is Fire, and Fire is Salt, and they contain in themselves a third thing, to wit, an hidden Spirit. ”
