"The universe (which others call the Library) is composed of an indefinite, perhaps an infinite, number of hexagonal galleries, with enormous ventilation shafts in the middle, encircled by very low railings. From any hexagon the upper or lower stories are visible, interminably. The distribution of the galleries is invariable. Twenty shelves - five long shelves per side - cover all sides except two; their height, which is that of each floor, scarcely exceeds that of an average librarian. One of the free sides gives upon a narrow entrance way, which leads to another gallery, identical to the first and to all the others. To the left and to the right of the entrance way are two miniature rooms. One allows standing room for sleeping; the other, the satisfaction of fecal necessities. Through this section passes the spiral staircase, which plunges down into the abyss and rises up to the heights. In the entrance way hangs a mirror, which faithfully duplicates appearances. People are in the habit of inferring from this mirror that the Library is not infinite (if it really were, why this illusory duplication?); I prefer to dream that the polished surfaces feign and promise infinity....

Light comes from some spherical fruits called by the name of lamps. There are two, running transversally, in each hexagon. The light they emit is sufficient, incessant.

Like all men of the Library, I have traveled in my youth. I have journeyed in search of a book, perhaps of the catalogue of catalogues; now that my eyes can scarcely decipher what I write, I am preparing to die a few leagues from the hexagon in which I was born. Once dead, there will not lack pious hands to hurl me over the banister; my sepulchre shall be the unfathomable air; my body will sink lengthily and will corrupt and dissolve in the wind engendered by the fall, which is infinite. I affirm that the Library is interminable. The idealists argue that the hexagonal halls are a necessary form of absolute space or, at least, of our intuition of space. They contend that a triangular or pentagonal hall is inconceivable. (The mystics claim that to them ecstasy reveals a round chamber containing a great book with a continuous back circling the walls of the room; but their testimony is suspect; their words, obscure. That cyclical book is God.) Let it suffice me, for the time being, to repeat the classic dictum: The Library is a sphere whose consummate center is any hexagon, and whose circumference is inaccessible.
