Lecture I

[^18]: Nicholas Copernicus: Thorn 1473–1543 Frauenburg. Humanist, mathematician, astronomer, physician, lawyer. No publications during his life, with the exception of a translation. Finished his work on the heliocentric planetary system around 1507. Copernicus was already on his deathbed when his De Revolutionibus Orbium Coelestium was published. He dedicated it to Pope Paul III. His friend and publisher introduced it as a purely hypothetical, special scientific method of calculation. It thus slipped past the censor, until the third edition was banned in 1616/17. Not until 1822 was it accepted by the Catholic Church, cf. Rudolf Steiner, The Spiritual Guidance of Man. (Spring Valley, NY: Anthroposophic Press, 1983).
