| Empyrean Heaven | The location of God and all the saved souls. This Christianized Ptolemaic uiverse, then was finite. It had a fixed outer boundary in harmony with Christian thought and saved souls were, at one end of the universe, & humans were at the center. |
| Epicycles | Concentric spheres within spheres, that would enable the paths of the planets to correspond more precisely to observations while adhering to Aristotle's ideas of circular planetary movement. |
| Nicolous Copernicus | Studied both mathematics and astronomy first at krakow in his native Poland and later at the Italian universities of Bologna ad Padua. Left Italy in 1506. |
| On the Revolutions fo the Heavenly SPheres | Nicolaus Copernicus completed the manuscript of his famous book....but he feared ridiculed from other Astonomers that he waited to publish it until May 1543, shortly before his . |

| Tycho Brahe | was granted possesion of a island near Copenhagen by King Fredrick II. He built the elaborate Uraniborg Castle, which was outfitted by a library, observations, and instruments he had designed for more precise astrtonomical observations |
| Johannes Kepler | He had been destined by his parents for a career as a Lutheran Minister. He fell under the influence of Michael Mastiln, German astronomer. He illustrated the narrow line that other separated majic and science in the early scientific Revolution |
| Three Laws of Planetary Motion | These laws may have confirmed Kepler's interest in the "music of the spheres" they confirmed Copernicus's heliocentric theory, modifying it in some ways |
| Galileo Galilei | Taught mathematics. One of the most pretigious univeristies in Europe. First European to make syystematic observations of the heavens by means of wa warrier. |
| The Starry Messengers | Stunned his counterparts and probably did more to make Europeans aware of the new picture of the universe than the mathematical theories of Copernicus and Kepler did. |
| Dialogue on the Two Chief WOrld Systems | Unlike most scholarly treaties, it was written in Italian rather than Latin, making it more widely available to the public, which no doubt alarmed the church authorities. |
