"I would give anything to see that picture," Emberlin added, after a pause. "The colouring, you know; Zuylerius gives no hint, but I feel somehow certain that the dominant tone must have been a fierce brick-red--a red granite amphitheatre filled with a red-robed assembly, sharply defined against an implacable blue sky." "Their eyes would be green," I suggested. Emberlin closed his eyes to visualize the scene and then nodded a slow and rather dubious assent. "Up to this point," Emberlin resumed at length, "Zuylerius' account is very clear. But his descriptions of the later philarithmic art become extremely obscure; I doubt whether he understood in the least what it was all about. I will give you such meaning as I manage to extract from his chaos. Eupompus seems to have grown tired of painting merely numbers of objects. He wanted now to represent Number itself. And then he conceived the plan of rendering visible the fundamental ideas of life through the medium of those purely numerical terms into which, according to him, they must ultimately resolve themselves. Zuylerius speaks vaguely of a picture of Eros, which seems to have consisted of a series of interlacing planes. Eupompus' fancy seems next to have been taken by various of the Socratic dialogues upon the nature of general ideas, and he made a series of illustrations for them in the same arithmo-geometric style. Finally there is Zuylerius' wild description of the last picture that Eupompus ever painted. I can make very little of it. The subject of the work, at least, is clearly stated; it was a representation of Pure Number, or God and the Universe, or whatever you like to call that pleasingly inane conception of totality. It was a picture of the cosmos seen, I take it, through a rather Neoplatonic _camera obscura--_very clear and in small. Zuylerius suggests a design of planes radiating out from a single point of light. I dare say something of the kind came in. Actually, I have no doubt, the work was a very adequate rendering in visible form of the conception of the one and the many, with all the intermediate stages of enlightenment between matter and the _Fons Deitatis_. However, it's no use speculating what the picture may have been going to look like. Poor old Eupompus went mad before he had completely finished it and, after he had dispatched two of the admiring Philarithmics with a hammer, he flung himself out of the window and broke his neck. That was the end of him, and that was how he gave splendour, regrettably transient, to Art by Numbers." Emberlin stopped. We brooded over our pipes in silence; poor old Eupompus! * * * * * That was four months ago, and to-day Emberlin is a confirmed and apparently irreclaimable Philarithmic, a quite whole-hearted Eupompian.
