“Centuries and centuries of idealism have not failed to influence reality. In the very oldest regions of Tlön, it is not an uncommon occurrence for lost objects to be duplicated. . . . These secondary objects are called hrönir and, even though awkward in form, are a little larger than the originals.

One curious fact: the hrönir of the second and third degree - that is, the hrönir derived from another hrön, and the hrönir derived from the hrön of a hrön - exaggerate the flaws of the original; those of the fifth degree are almost uniform; those of the ninth can be confused with those of the second; and those of the eleventh degree have a purity of form which the originals do not possess.”
