§ =27.= The Elixir of Life, which was generally described as a solution of the Stone in spirits of wine, or identified with the Stone itself, could be applied, so it was thought, under certain conditions to the alchemist himself, with an entirely analogous result, _i.e._, it would restore him to the flower of youth. The idea, not infrequently attributed to the alchemists, that the Elixir would endow one with a life of endless duration on the material plane is not in strict accord with alchemistic analogy. From this point of view, the effect of the Elixir is physiological perfection, which, although ensuring long life, is not equivalent to endless life on the material plane. “The Philosophers’ Stone,” says Paracelsus, “purges the whole body of man, and cleanses it from all impurities by the introduction of new and more youthful forces which it joins to the nature of man.”[38] And in another work expressive of the opinions of the same alchemist, we read: “. . . there is nothing which might deliver the mortal body from death; but there is One Thing which may postpone decay, renew youth, and prolong short human life . . .”[39] In the theory that a solution of the Philosopher’s Stone (which, it must be remembered, was thought to be of a species with gold) constituted the _Elixir Vitæ_, can be traced, perhaps, the idea that gold in a potable form was a veritable cure-all: in the latter days of Alchemy any yellow-coloured liquid was foisted upon a credulous public as a medicinal preparation of gold.
