Overview Copernicus Conclusion Further discussion His life His theory His inspirations: Ptolemy Hermes Trismegistus Conclusion Further discussion

Copernicus: his life Born on 19th Feb, 1473 in Thorn as Nicholas Koppernigk Some facts of life Main Publication: De revolutionibus orbium coelestium in 1543

Copernicus: his theory From geocentric to heliocentric The planetary character of the earth Earth in motion: daily rotation on its axis

Copernicus: his inspirations Hermers Trismegistus, pavement, Siena Cathedral Source : Giordano Bruno – and the Hermetic Tradition by Frances A. Yates Ptolemy: an image of how he could look like

Ptolemy’s Epicycle on a Deferent Circle Source: The Scientific Revolution – Aspiration and Achievements, 1500-1700 by James R. Jacob

Ptolemy’s Equant Circle Source: The Scientific Revolution – Aspiration and Achievements, 1500-1700 by James R. Jacob

Paradise Lost …when they come to model Heav’n And calculate the Stars, how they will wield The mighty frame, how build, unbuild, contrive To save appearances, how gird the Sphere With Centric and Eccentric scribbled o’er, Cycle and Epicycle, Orb in Orb… John Milton

Hermes Trismegistus An Egyptian priest living around 1000 B.C. or even before Hermetic writings : 21 books Hermetic tradition : harmony between micro-cosmos (=man) and macro-cosmos (=universe) The Sun = second God = the Demiurg = the Maker of All

In the middle of all sits the Sun enthroned In the middle of all sits the Sun enthroned. How could we place this luminary in any better position in this most beautiful temple from which to illuminate the whole at once? He is rightly called the Lamp, the Mind, the Ruler of the Universe… De revolutionibus orbium coelestium, p. 30

Did Hermes Trismegistus really exist? But Did Hermes Trismegistus really exist?

Conclusion Copernicus was rational, but he got his ideas from the hermetic writings. He made it into science by calculating to show its correctness. In general: Renaissance magic is an important factor in the changing of the human outlook.

The End Any ideas? Any questions? Any suggestions? SHOOT!
