The bones were used to make a facial reconstruction. However when Copernicus died in 1543 at the age of 70 he was not a celebrity, so few paintings of him are available with which to make a comparison .
His famous book De Revolutionibus Orbium Coelestium (On the Revolutions of the Heavenly Spheres), in which he first proposed that the Earth revolves around the Sun, was largely ignored when it was first published. However, after Galileo, the heliocentric universe became firmly established and ensured that Copernicus 's name now stands as one of the most significant in the history of science.
The library of the RAS holds a reproduction, in full colour, of the autograph of De Revolutionibus which is preserved in the Jagiellonian Library in Cracow.
