Sketch for La Mondothèque. Paul Otlet, 1935?

An axonometric view of the Mundaneum gives the effect of an aerial photograph of an archeological site — Egyptian, Babylonian, Assyrian, ancient American (Mayan and Aztec) or Peruvian. These historical reminiscences are striking. Remember the important building works of the Mayas, who were the zenith of ancient American civilization. These well-known ruins (Uxmal, Chichen-Itza, Palenque on the Yucatan peninsula, and Copan in Guatemala) represent a “metaphysical architecture” of special cities of religious cults and burial grounds, cities of rulers and priests; pyramids, cathedrals of the sun, moon and stars; holy places of individual gods; graduating pyramids and terraced palaces with architectural objects conceived in basic geometrical shapes of cube, cylinder, prism and pyramid, the main axis of which is symmetry with emphasis on horizontality.

The universe (which others call the Library) is composed of an indefinite and perhaps infinite number of triangular galleries, with vast air shafts between, surrounded by very low railings. From any of the triangles one can see, interminably, the upper and lower floors. The distribution of the galleries is invariable.

The ship wherein Theseus and the youth of Athens returned had thirty oars, and was preserved by the Athenians down even to the time of Demetrius Phalereus, for they took away the old planks as they decayed, putting in new and stronger timber in their place, insomuch that this ship became a standing example among the philosophers, for the logical question of things that grow; one side holding that the ship remained the same, and the other contending that it was not the same.

The face of the earth would be much altered if brick architecture were ousted everywhere by glass architecture. It would be as if the earth were adorned with sparkling jewels and enamels. Such glory is unimagmable. We should then have a paradise on earth, and no need to watch in longing expectation for the paradise in heaven.

"Alimentation. — La base de notre alimentation repose en principe sur un trépied. 1° Protides (viandes, azotes). 2° Glycides (légumineux, hydrates de carbone). 3° Lipides (graisses). Mais il faut encore pour présider au cycle de la vie et en assurer la régularité, des vitamines : c’est à elles qu’est due la croissance des jeunes, l’équilibre nutritif des adultes et une certaine jeunesse chez les vieillards."

The “Sacrarium,” is something like a temple of ethics, philosophy, and religion. A great globe, modeled and colored, in a scale 1 = 1,000,000 with the planetarium inside, is situated in front of the museum building.

Toute la Documentation. A late sketch from 1937 showing all the complexity of the pyramid of documentation. An evolutionary element works its way up, and in the conclusive level one can read a synthesis: "Homo Loquens, Homo Scribens, Societas Documentalis".
