Newton extended one hand, palm up, and Eliza supposed for a moment that he was directing her attention to the window set into the wall above this table. But Newton waved his hand around in the air as if trying to catch a moth, and finally steadied it. His palm, which was as pale as parchment, was striped with a little rainbow, projected by some bevel or irregularity in the windowpane. Eliza turned her attention to it. The swath of colors was steady as a gyroscope on a stand, even though Newton’s hand never stopped moving. This was a trompe l’oeil to best anything daubed on a wall by a mischievous painter at Versailles. Eliza acted without thinking: she reached out with both hands, cupping them together beneath Newton’s, and cradled his wayward hand in hers, steadying it. “I see that you are unwell,” she said, “for this is not the tremor of a coffee-enthusiast, but the shivering of a man with a fever.” Yet Newton’s hand felt cold.
“We are all unwell, if it comes to that,” Newton returned, “for if some Plague were to take us all, why, these little spectra would still crawl about the room until the End of Days, neither knowing nor caring whether living hands were held up to catch them. Our flesh stops the light. The flesh is weak, yes, but the spirit is strong, and by applying our minds to the contemplation of what has been interrupted by our fleshly organs of sense, we may make our minds wiser and our spirits better, even though flesh decays. Now! I do not have a fever, my lady.” He took his hand back, and gripped the arm of his chair to stop its shivering. The little rainbow now fell on Eliza’s cupped hands. “But I am mortal and would fain do all that I could, in the time allotted to me, to penetrate this mystery of Force. Now consider this light that you are catching in your hands. It has traveled a hundred million miles from the Sun without being affected in any wise by the C?lestial ?ther. In its passage through the atmosphere it has been subjected to only slight distortions. And yet in traversing a quarter of an inch of window-glass, its course is bent, and it is riven into several colors. It is such an everyday thing that we do not mark it; yet pray consider for a moment just how remarkable it is! During its hundred-million-mile passage, is it not acted upon by the gravity of the Sun, which is powerful enough to hold even mighty Jupiter in its grasp, though at a much greater remove? And is it not acted upon as well by the gravity of the Earth and Moon, and all the other planets? And yet it seems perfectly insensitive to thse mighty forces. Yet there is embedded within this shard of glass some hidden Force that bends it and splits it with no effort. It’s as if a cannonball, hurled at infinite speed from some gun of inconceivable might, and passing through ramparts and bulwarks as if they were shadows, were deflected and shivered into bits by a child holding up a feather. What could be concealed within an ordinary piece of window-glass that harbors such potency, and yet affects you and me not at all? Or consider the action of acids, which can in a few moments dissolve stones that have stood unmarked by Time and the elements since the world was formed. What has the power to annihilate a stone God made, a stone that could support a Pyramid, stop fire, or turn aside musket-balls? Some force of immense power must be latent in acids, to destroy what is so strong. And is it so inconceivable that this force might be akin to, or the same as, what bends the light as it passes through the window? Are these not perfectly suitable questions to be asked by those who style themselves Natural Philosophers?”
“If only others who study Alchemy would form their questions so well, and state them so lucidly!” Eliza said.
“The traditions of the Art are ancient and strange. Alchemists, when they say aught, say it in murky similitudes. This is not for me to remedy, save by pursuing the Work to its proper conclusion and thereby making plain what has been occulted for so many centuries. And it is concerning that Work that I should like to say something to you concerning the gold that Jack Shaftoe stole in Bonanza.”
This was such an unexpected turn in the conversation that Eliza flopped back hard in her chair, like a doll tossed into a box. Fatio turned his face toward her and stared avidly. Newton seemed ever so drily amused by her astonishment. “I do not know the nature of your involvement with this, my lady, and it is neither my place, nor my desire, to quarry the truth out of you. It suffices that you are believed, by diverse members of the Esoteric Brotherhood, to know something about the matter; and as long as that is true, why, it is in your interest to know why Alchemists care so much about this gold. Do you know, my lady?”
“I know, or suspect, only what I have inferred from the words and deeds of certain men who desire it. Those men believe that this particular gold has some supernatural properties exceeding normal gold.”
“I do not know what the word supernatural means, really,” said Isaac, bemused. “But you are not far wrong.”
