See also:COPERNICUS (or KOPPERNIGK), NICOLAUS (1473-1543)
, See also:Polish astronomer, was See also:born on the 19th of See also:February 1493, at See also:Thorn in Prussian See also:Poland, where his See also:father, a native of See also:Cracow, had settled as a wholesale trader
.
His See also:mother, See also:Barbara Watzelrode, belonged to a See also:family of high See also:mercantile and civic See also:standing
.
After the See also:death of his father in 1483, Nicolaus was virtually adopted by his See also:uncle See also:Lucas Watzelrode, later (in 1489) See also:bishop of See also:Ermeland
.
Placed at the university of Cracow in 1491, he devoted himself, during three years, to mathematical See also:science under See also:Albert Brudzewski (1445-1497), and incidentally acquired some skill in See also:painting
.
At the See also:age of twenty-three he repaired to See also:Bologna, and there varied his studies of See also:canon See also:law by attending the astronomical lectures of Domenico Maria See also:Novara (1454-1504)
.
At See also:Rome, in the See also:Jubilee See also:year 1500, he himself lectured with See also:applause; but having been nominated in 1497 canon. of the See also:cathedral of See also:Frauenburg, he recrossed the See also:Alps in 1501 with the purpose of obtaining further leave of See also:absence for the completion of his See also:academic career
.
See also:Late in the same year, accordingly, he entered the medical school of See also:Padua, where he remained until 1505, having taken meanwhile a See also:doctor's degree in- canon law at See also:Ferrara on the 31st of May 1503
.
After his return to his native See also:country he resided at the episcopal See also:palace of See also:Heilsberg as his uncle's physician until the latter's death on the 29th of See also:
His dissatisfaction with Ptolemaic doctrines was of See also:early date; and he returned from See also:Italy, where so-called See also:Pythagorean opinions were then freely discussed, in strong and irrevocable See also:possession of the See also:heliocentric theory
.
The See also:epoch-making See also:treatise in which it was set forth, virtually finished in 1530, began to be known through the circulation in See also:manuscript of a Commentariolus, or brief popular See also:account of its purport written by See also:Copernicus in that year
.
Johann Albrecht Widmanstadt lectured upon it in Rome; See also:Clement VII. approved, and See also:Cardinal Schonberg transmitted to the author a formal demand for full publication
.
But his assent to this was only extracted from him in 1540 by the importunities of his See also:friends, especially of his enthusiastic See also:disciple See also:George See also:Joachim See also:Rheticus (1514-1576), who printed, in the Narratio prima (See also:Danzig, 1540), a preliminary account of the Copernican theory, and simultaneously sent to the See also:press at See also:Nuremberg his See also:master's See also:complete exposition of it in the treatise entitled De revolutionibus orbium coelestium (1543)
.
But the first printed copy reached Frauenburg barely in time to be laid on the writer's death-See also:bed
.
Copernicus was seized with See also:apoplexy and See also:paralysis towards the See also:close of 1542, and died on the 24th of May 1543, happily unconscious that the See also:fine See also:Epistle, in which he had dedicated his See also:life's work to See also:Paul III., was marred of its effect by an See also:anonymous -See also:preface, slipt in by Andreas See also:Osiander (1498-1552), with a view to disarming See also:prejudice by insisting upon the purely hypothetical
See also:character of the reasonings it introduced
.
The trigonometrical See also:section of the See also:book had been issued as a See also:separate treatise (See also:Witten-See also:berg, 1542) under the care of Rheticus
.
The only work published by Copernicus on his own initiative was a Latin version of the See also:Greek Epistles of See also:Theophylact (Cracow, 1509)
.
His treatise De monetae cudendae ratione, 1526 (first printed in 1816), written by See also:order of See also: It was supplemented, during the 19th See also:century, by the various publications of J . Sniadecki (See also:Warsaw, 18o3—1818); of J . H . W . See also:Westphal, J . Czynski, M . Curtze, H . A . Wolynski, F . Hipler, and others, but their efforts were overshadowed by Dr See also:Leopold Prowe's exhaustive Nicolaus Coppernicus (See also:Berlin, 1883—1884), embodying the outcome of researches indefatigably prosecuted for over See also:thirty years . The first See also:volume (in two parts) is a detailed See also:biography of the great astronomer; the second includes some of his See also:minor writings and See also:correspondence, family records, and See also:historical documents of See also:local See also:interest . The effects of his See also:Italian sojourn upon the nascent ideas of Copernicus may be profitably studied in Domenico Berti's Copernico e le vicende del sistema Copernicano in Italia (See also:Roma, 1876), and in G . V . See also:Schiaparelli's I Precursori del Copernico nell' antichild (Milano, 1873) . A See also:centenary edition of De revolutionibus orbium coelestium was issued at Thorn in 1873, and a See also:German See also:translation by C . L . Menzzer in 1879 . (A . M . C.) COPIAPb, a See also:city of See also:northern See also:Chile, See also:capital of the See also:province of See also:Atacama, about 35 M. from the See also:coast on the Copiapo See also:river, in See also:lat . 27° 36' S., See also:long . 70° 23' W . Pop . (1895) 9301 . The Caldera & Copiapo railway (built 1848—1851 and one of the first in See also:South See also:America) extends beyond Copiapo to the Chanarcillo mines (5o m.) and other See also:mining districts . Copiapo stands 1300 ft. above See also:sea-level and has a mean temperature of about 67° in summer and 51° in See also:winter . Its See also:port, Caldera, 50 M. distant by See also:rail, is situated on a well-sheltered See also:bay with See also:good See also:shipping facilities about 6 m . N. of the mouth of the Copiapo river . Copiapo is perhaps the best built and most attractive of the See also:desert region cities . The river brings down from the mountains enough See also:water to See also:supply the See also:town and irrigate a considerable See also:area in its vicinity . Beyond the small fertile valley in which it stands is the barren desert, on which See also:rain rarely falls and which has no economic value apart from its minerals (especially saline compounds) . Copiapo was founded in 1742 by Jose de Manso (afterwards See also:Conde, de Superunda, See also:viceroy of See also:Peru) and took its name from the Copayapu See also:Indians who occupied that region . It was primarily a military station and transport See also:post on the road to Peru, but after the See also:discovery of the rich See also:silver deposits near Chanarcillo by Juan See also:Godoy in 1832 it became an important mining centre . It has a good mining school and reduction See also:works, and is the supply station for an extensive mining See also:district . For many years the Famatina mines of See also:Argentina received supplies from this point by way of the Come-Caballo pass . |
