Elias Ashmole writes in his diary—“May 13, 1653. My father Backhouse (an Astrologer who had adopted him for his son—a common practice with these men) lying sick in Fleet Ditch, over against St. Dunstan’s church, and not knowing whether he should live or die, about eleven of the clock told me in _Syllables_ the true matter of the _Philosopher’s Stone_, which he bequeathed to me as a legacy.” By this we learn that a miserable wretch knew the art of _making gold_, yet always lived a beggar; and that Ashmole really imagined he was in possession of the _Syllables of a secret_! he has however built a curious monument of the learned follies of the last century, in his “Theatrum Chemicum Britannicum.” Though Ashmole is rather the historian of this vain science than an adept, it may amuse literary leisure to turn over his quarto volume, in which he has collected the works of several English Alchymists, to which he has subjoined his Commentary. It affords a curious specimen of Rosicrucian Mysteries; and Ashmole relates stories, which vie for the miraculous, with the wildest fancies of Arabian invention. Of the Philosopher’s Stone, he says, he knows enough to hold his tongue, but not enough to speak. This Stone has not only the power of transmuting any imperfect earthy matter into its utmost degree of perfection, and can convert the basest metals into gold, flints into stones, &c. but it has still more occult virtues, when the arcana have been entered into, by the choice fathers of hermetic mysteries. The vegetable stone has power over the natures of man, beast, fowls, fishes, and all kinds of trees and plants, to make them flourish and bear fruit at any time. The magical stone discovers any person wherever he is concealed; while the angelical stone gives the apparitions of angels, and a power of conversing with them. These great mysteries are supported by occasional facts, and illustrated by prints of the most divine and incomprehensible designs, which we would hope were intelligible to the initiated. It may be worth shewing, however, how liable even the latter were to blunder on these Mysterious Hieroglyphics. Ashmole, in one of his chemical works, prefixed a frontispiece, which, in several compartments, exhibited Phœbus on a lion, and opposite to him a lady, who represented Diana, with the moon in one hand and an arrow in the other, sitting on a crab; Mercury on a tripod, with the scheme of the heavens in one hand, and his caduceus in the other. They were intended to express the materials of the Stone, and the season for the process. Upon the altar is the bust of a man, his head covered by an astrological scheme dropped from the clouds; and on the altar are these words, MERCURIOPHILUS ANGLICUS, _i. e._ the English lover of hermetic philosophy. There is a tree and a little creature gnawing the root, a pillar adorned with musical and mathematical instruments, and another with military ensigns. This strange composition created great inquiry
