Some Peradam I’ve Collected. Stereograph 2018. René Daumal: "One finds here, very rarely in the low lying areas, more frequently as one goes farther up, a clear and extremely hard stone that is spherical and varies in size—a kind of crystal, but a curved crystal, something extraordinary and unknown on the rest of the planet. Among the French of Port-des-Singes, it is called peradam. Ivan Lapse remains puzzled by the formation and root meaning of this word. It may mean, according to him, "harder than diamond," and it is; or "father of the diamond," and they say that the diamond is in fact the product of the degeneration of the peradam by a sort of quartering of the circle or, more precisely, cubing of the sphere. Or again, the word may mean "Adam's stone," having some secret and profound connection to the original nature of man. The clarity of this stone is so great and its index of refraction so close to that of air that, despite the crystal's great density, the unaccustomed eye hardly perceives it. But to anyone who seeks it with sincere desire and true need, it reveals itself by its sudden sparkle, like that of dewdrops. The peradam is the only substance, the only material object whose value is recognized by the guides of Mount Analogue. Therefore, it is the standard of all currency, as gold is for us."
