Copernicus and the Old Bond of Metal and Heaven

Copernicium honours Nicolaus Copernicus, the Renaissance astronomer whose heliocentric model displaced the Earth from the centre of the cosmos and set the modern understanding of the solar system in motion. The discoverers noted a deliberate resonance in the choice: the ancient alchemists had bound the seven metals to the seven heavenly bodies, gold to the Sun, silver to the Moon, and the rest to the planets, and by naming a metal for the man who reordered the heavens, they consciously echoed that old link between the metals and the sky. It is a rare instance of a modern element-naming reaching back, knowingly, to the astrological tradition that once governed the metals. Copernicium has no tradition of its own, being a synthetic element of the 1990s, but its name is a thoughtful nod to the long marriage of metal and planet.

Copernicus himself was, notably, a canon of the Catholic Church throughout his career, making the later religious controversy over his astronomy a dispute that unfolded, in a real sense, within the Church's own ranks rather than simply between science and faith as separate camps. That inside position did nothing to spare his work from official censure decades after his death.
