First known observation

Mar 9, 1497

The first such known observation occurred on March 9, 1497 at Bologna. In De Revolutionibus, book 4, chapter 27, Copernicus reported that he had seen the Moon eclipse, "the brightest star in the eye of the Bull," Alpha Tauri (Aldebaran).

Commentariolus

Mar 16, 1513

outlined the material he later discussed more fully. His main points were that the Ptolemaic system of a geocentric planetary model was complex, unwieldy and inaccurate. Copernicus proposed to replace Ptolemy's ideas with a model in which the planets (including the Earth) orbited a centrally situated Sun. The Earth would describe one full orbit of the Sun in a year, while the Moon orbited the Earth.

The only work published by Copernicus on his own initiative was a Latin version of the Greek Epistles of Theophylact (Krakow, 1509)

Oct 8, 1526

His treatise De monetae cudendae ratione, 1526 (first printed in 1816), written by order of King Sigismund I, is an exposition of the principles on which it was proposed to reform the currency of the Prussian provinces of Poland. It advocates unity of the monetary system throughout the entire state, with strict integrity in the quality of the coin, and the charge of a seigniorage sufficient to cover the expenses of mintage.

Narratio prima "Frist narration"

Mar 16, 1540

Rheticus, a Lutheran from the University of Wittenberg, Germany, stayed with Copernicus at Frauenburg for about two and a half years, between 1539 and 1542. The Narratio Prima was, in effect, a joint production of Copernicus and Rheticus, something of a "trial balloon" for the main work.It provided a summary of the theoretical principles contained in the manuscript of De revolutionibus. http://www.britannica.com.libproxy.noctrl.edu/EBchecked/topic/136591/Nicolaus-Copernicus

Nicolaus copernicas dies

May 24, 1543

Copernicus was seized with apoplexy and paralysis towards the close of 1542, and died on the 24th of May 1543, happily unconscious that the fine Epistle, in which he had dedicated his life's work to Pope Paul III, was marred of its effect by an anonymous preface, http://www.nndb.com/people/041/000029951/

Nicolaus Copernicus Book was Published

May 24, 1553

Copernicus published On the Revolution of the Heavenly Spheres. The book was a revolution making rather than a revolutionary text. It was to provide intellectual springboard for a complete critism of the then-dominant view of the postion of the earth in the universe.
