It is about the Revolutions of the Heavenly Spheres, it is by Nicolaus Copernicious.
Copernicus
Copernicus published his heliocentric theory in 1543 in his book "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Celestial Spheres).
The theory was published in a famous book entitled (in Latin): 'De revolutionibus orbium coelestium', which means, 'On the revolutions of the orbs of the heavens'.
Nicolaus Copernicus was a Renaissance astronomer and the first person to formulate a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe. Copernicus dedicated the book to Paul III who was known for his astrological predilection. De Revolutionibus was a book and when he published it the gov't didn't want to get rid of the Earth-Centered (Geocentric) Theory so before they published De Revolutionibus, they wrote in the beginning of the book that the stuff written in the book was all fictional. The book was published in March 1543.
From Wikipedia: "De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) is the seminal work on the heliocentric theory of the Renaissance astronomer Nicolaus Copernicus (1473-1543)."
