A Year: Day to Day Men: 5th of March
The White Stetson
On March 5, 1616, Nicolaus Copernicus’s book “On the Revolutions of the Heavenly Spheres” is added to the index of Forbidden Books by the Roman Catholic Church.
“On the Revolutions of the Heavenly Spheres” is the seminal work on the heliocentric (sun-centered) theory of the solar system by the Renaissance astronomer Nicolaus Copernicus. The book, first printed in 1543 in Nuremberg, offered an alternative model of the universe to Ptolemy’s geocentric system (earth-centered), which had been popular since ancient times.
Copernicus argued that the universe comprised eight spheres. The outermost consisted of motionless, fixed stars, with the Sun motionless at the center. The known planets revolved about the Sun, each in its own sphere, in the order: Mercury, Venus, Earth, Mars, Jupiter, Saturn. The Moon, however, revolved in its sphere around the Earth. What appeared to be the daily revolution of the Sun and fixed stars around the Earth was actually the Earth’s daily rotation on its own axis.
Very soon, Copernicus’ theory was attacked with Scripture and with the common Aristotelian proofs. In 1549 Melanchthon, Martin Luther’s principal lieutenant, wrote against Copernicus, pointing to the theory’s apparent conflict with Scripture and advocating that “severe measures” be taken to restrain the impiety of Copernicans. The works of Copernicus and Zúñiga—the latter for asserting that Copernicus’ book was compatible with Catholic faith—were placed on the Index of Forbidden Books by a decree of the Sacred Congregation of March 5, 1616 (more than 70 years after its publication).
Copernicus’ book was not formally banned but merely withdrawn from circulation, pending “corrections” that would clarify the theory’s status as hypothesis. Nine sentences that represented the heliocentric system as certain were to be omitted or changed. After these corrections were prepared and formally approved in 1620 the reading of the book was permitted. But the book was never reprinted with the changes and was available in Catholic jurisdictions only to suitably qualified scholars, by special request. It remained on the Index until 1758, whenPope Benedict XIV (1740–58) removed the uncorrected book from his revised Index.
