“In the middle of all sits the Sun enthroned.”

Copernicus, De revolutionibus I

Who Nicolaus Copernicus was

Copernicus studied canon law and medicine in Italy and spent most of his adult life as a canon of Frombork cathedral, managing estates, advising on currency reform and treating patients. Astronomy was what he did around the edges. He circulated a short handwritten sketch of a Sun-centred system around 1514, then worked for decades on the full argument. De revolutionibus orbium coelestium reached him, according to the story, on the day he died in 1543. It did not immediately convince anyone — his circles and epicycles were no simpler than Ptolemy's — but it reframed the question, and Kepler, Galileo and Newton built on the shift.
