The glittering stars move as a whole each year the sun returns to a backdrop of bright points very near the one it left. It rises daily in the east, until by nightfall it hides behind some horizon, whether land, sea or cloud, diving unseen to reappear at dawn in a different part of the starry background. We draw life from the glorious, incandescent sun.

Of course, almanacs for the elite cannot be prepared without numbers and geometry, but the architecture as a whole can be disclosed by much simpler arguments grade school experience suffices. The contents support a remarkably simple way of envisioning how members of the sun's family, including our home planet, make their circumsolar rounds.

Recent scholarship has uncovered early commentary from Copernicus on the sun-centered solar system, made when he was about 35 or 40. His literary executors were seriously worried about the impact of his new work one of them added a preface to temper the author's well-supported claims. His almanac tables, showing the moon and Earth with the planets revolving about the sun, met the test of expert observation as well as the old Earth-centered tables had. His celebrated full volume, On the Revolutions of the Celestial Spheres, was published three decades later, in Nuremberg in 1543, the year he died. That phase passed when Lucas died in 1512, and Copernicus embarked on long and varied service for and around the Frombork cathedral. He improved and circulated it privately in Italy, and during quieter years with his bishop. With age he rose to higher administrative positions, although he probably never became a priest.īy his thirties Copernicus had developed a heliocentric theory of the solar system in a document of a few fruitful pages. He made maps, attended legislative bodies, held a variety of fiscal posts, acted as diplomat and as civil and military inspector, even wrote a treatise on the minting of money by the new Prussian states. For years thereafter he attended his bishop uncle as official physician in fact, most of his life was passed fulfilling a dozen diverse appointments as a church official going wherever in stormy times a learned and productive mind was of use.
