Largely unknown outside his homeland, Jan Matejko (1838-93) is widely regarded as the national painter of Poland, where he is revered for his huge minutely detailed depictions of key moments in the nation’s history. Focusing on Matejko’s masterpiece, Copernicus, this generously illustrated book introduces the artist to a wider public. His monumental painting celebrates the achievements of Polish astronomer Nicolaus Copernicus (1473-1543), whose heliocentric theory transformed our understanding of the universe. Rather than depicting Copernicus at the moment of his discovery Matejko chose to paint him on a rooftop in his hometown of Frombork, discussing the matter with God. Copernicus was never excommunicated for challenging the authority of the church; indeed, enlightened clerics of the day celebrated his breakthrough.
