The second article of agreement, that of Proserpine’s remaining six months with her mother and six with her husband, is an elegant description of the division of the year; for the spirit diffused through the earth lives above-ground in the vegetable world during the summer months, but in the winter returns under ground again. The attempt of Theseus and Perithous to bring Proserpine away, denotes that the more subtile spirits, which descend in many bodies to the earth, may frequently be unable to drink in, unite with themselves, and carry off the subterraneous spirit, but on the contrary be coagulated by it, and rise no more, so as to increase the inhabitants and add to the dominion of Proserpine.[649] The alchemists will be apt to fall in with our interpretation of the golden bough, whether we will or no, because they promise golden mountains, and the restoration of natural bodies from their stone, as from the gates of Pluto; but we are well assured that their theory had no just foundation, and suspect they have no very encouraging or practical proofs of its soundness. Leaving, therefore, their conceits to themselves, we shall freely declare our own sentiments upon this last part of the fable. We are certain, from numerous figures and expressions of the ancients, that they judged the conservation, and in some degree the renovation, of natural bodies to be no desperate or impossible thing, but rather abstruse and out of the common road than wholly impracticable. And this seems to be their opinion in the present case, as they have placed this bough among an infinite number of shrubs, in a spacious and thick wood. They supposed it of gold, because gold is the emblem of duration. They feigned it adventitious, not native, because such an effect is to be expected from art, and not from any medicine or any simple or mere natural way of working. XXX.—METIS, OR COUNSEL. EXPLAINED OF PRINCES AND THEIR COUNCIL. The ancient poets relate that Jupiter took Metis to wife, whose name plainly denotes counsel, and that he, perceiving she was pregnant by him, would by no means wait the time of her delivery, but directly devoured her; whence himself also became pregnant, and was delivered in a wonderful manner; for he from his head or brain brought forth Pallas armed.
