Sacred Geometry

Nature, which is never not lavish of herself, after a lying-in of two thousand years, has finally brought you forth in these last generations, the first true images of the universe. By means of your concords of various voices, and through your ears, she has whispered to the human mind, the favorite daughter of God the Creator, how she exists in the innermost bosom.–[p. 1040].Johannes Kepler, who originally studied theology, was introduced to the Copernican world-view while studying for his Master’s degree in Philosophy at the University of Tübingen. He wrote a paper attempting to reconcile the Copernican system with the Bible. Although he wanted to enter the ministry, he was offered a chair of astronomy at the Lutheran school of Graz, which he accepted.

He became convinced that there was a relationship between the five regular solids and the structure of the known solar system. His first work on Astronomy, Precursor of Cosmographic Dissertations or the Cosmographic Mystery, published in 1596, brought him to the attention of Tycho Brahe and Galileo. Banished from his homeland by an edict against Protestants in 1598, Kepler eventually ended up in Prague, where he worked under Tycho. On Tycho’s death, Kepler took over his post and inherited Tycho’s massive archive of observations.

Johannes Kepler published Harmonies of the World in 1619. This was the summation of his theories about celestial correspondences, and ties together the ratios of the planetary orbits, musical theory, and the Platonic solids. Kepler’s speculations are long discredited. However, this work stands as a bridge between the Hermetic philosophy of the Renaissance, which sought systems of symbolic correspondences in the fabric of nature, and modern science. And today, we finally have heard the music of the spheres: data from outer system probes have been translated into acoustic form, and we can listen to strange clicks and moans from Jupiter’s magnetosphere.

Towards the end of Harmonies Kepler expressed a startling idea,–one which Giordiano Bruno had been persecuted for, two decades before–the plurality of inhabited worlds. He muses on the diversity of life on Earth, and how it was inconceivable that the other planets would be devoid of life, that God had “adorned[ed] the other globes too with their fitting creatures”.
