Dava Sobels' "A More Perfect Heaven" is a biography of Polish mathematician and astronomer Nicholas Copernicus, a history of the development of his theory of a sun-centric solar system, and an engaging look into a Europe on the cusp of transitioning from a dark and paranoid medieval society to an enlightened and brighter renaissance future.
While the focus of Sobels' work is her history of Copernicus the man, his science and mathematics, Sobels' biggest victory is her fictionalized drama of how Copernicus' only student, Rheticus, eventually convinced Copernicus to complete his work and share his theory and proofs of a sun-centric universe with the world.
I was reticent when I read that Sobel had included a dramatic play smack in the middle of her history. First, I've found plays difficult to read and couldn't imagine how it could seamlessly integrate into Sobels' work. Second...what? A play? In the middle of a history?
But it worked. It worked very well as a matter of fact. Sobels' play imagines the interactions between Rheticus, a young mathematics professor from Wittenberg, home of Martin Luther and the Protestant Reformation, and Copernicus in Poland. There's not a lot of action in the drama, so the dialogue-focused interplay successfully blends the historical characterizations into a very believable situation. Sobel peppers the preceding chapters with enough background on medieval Europe of the time as well as the participating characters that the 75 pages or so of the play work extremely well.
Surrounding the drama, Sobel serves heaping spoonfuls of a heavily religious dark ages Poland, and medieval astronomy.
She best summarizes the dramatic events surrounding Copernicus' work: "The bold plan for astronomical reform that Copernicus conceived and then nurtured over decades in his spare time struck him as the blueprint for the 'marvelous symmetry of the universe'...He proceeded cautiously, first leaking the idea to a few fellow mathematicians, never trying to proselytize. All the while real and bloody revolutions -- the Protestant Reformation, the Peasant Rebellion, warfare with the Teutonic Knights and the Ottoman Turks -- churned around him.
There are two elements of Copernicus' being that particularly impressed me. First, he was an extraordinarily literate man. Some of the quotes that Sobel includes in her book paint him in a uniquely poetic light. He wrote, for example, "Among the many various literary and artistic pursuits upon which the natural talents of man are nourished, I think the ones above all to be embraced and pursued with the most loving care concern the most beautiful and worthy objects, most deserving to be known. This is the nature of the discipline that deal with the god-like circular movement of the world and the course of the stars."
Second, Copernicus was an extremely detail-oriented individual. If the devil is in the details, then Copernicus, who was schooled in religion and lived in a very religiously oriented society, took that term to heart. Documentation still exists with the exhaustive notations he made while tracking and diagnosing the heavens, as well as his more earth-bound pursuits as an administrator for the Polish government/church. I've read about Galileo before and have always been utterly amazed at the patience and discipline it requires to track the course of the stars and heavenly bodies over the course of years. To remain doggedly at watch every single day, through wars, illness and weather, to gather such a wealth of detailed data reflects tremendous patience, focus and perhaps more than a little obsession.
The following was written in an 1878 publication of `Popular Astronomy', "The great merit of Copernicus, and the basis of his claim to the discovery in question, is that he was not satisfied with a mere statement of his views, but devoted a large part of the labor of a life to the demonstration, and thus laced them in such a light as to render their ultimate acceptance inevitable."
Copernicus first wrote on his concept of a sun-centered universe in 1510, over 30 years before he would finally find the courage and confidence to publish his full "On the Revolutions." His initial conclusions, Sobel writes, were reached through "intuition and mathematics. No astronomical observations were required." Copernicus wrote, "All spheres surround the Sun as though it were in the middle of all of them, and therefore the center of the universe is near the Sun. What appear to us as motions of the Sun arise not from its motion but from the motion of the Earth and our sphere, with which we revolve about the Sun like any other planet." Sobel writes that "with a wave of his hand, (Copernicus) had made the Earth a planet and set it spinning."
So what was Copernicus doing between 1510 and the publishing of his great work (and his death) in 1543, and why was he unable to be part of his work's impact on the world?
The spread of Lutheranism had great impact by creating a wide religious schism, spreading fear and limiting Copernicus' comfort in publishing his work. He was a very practical man and very attuned to the tone of church and politics, and how closely connected they were. Sobel writes, "With his book virtually complete by 1535, Copernicus lost courage. He worried that his labored calculations and tables would not yield the perfect match with planetary positions that he had aimed to achieve. He feared the public reaction. He empathized with the ancient sage Pythagoras, who had communicated his most beautiful ideas only to kinsmen and friends, and only by word of mouth. Despite the decade of effort invested in the text, Copernicus eschewed publication. If his theory appeared in print, he said, he would be laughed off the stage."
So during this time, he took a whole lot of astronomical measurements. There was not an eclipse, full moon, or shift in the position of the stars that Copernicus missed and documented. He was building his case that the Earth spun, and it and the other planets revolved around the Sun.
Copernicus was also a relatively highly placed administrator in the Polish government/church. Sobel points to extant documents that show his judgements in various cases regarding local law and commerce. Naturally, everything he touched was exhaustively detailed.
He was also a well-known and respected mathematician. Pope Leo X called on theologians and astronomers to help correct the flaws in the Julian calendar that were pushing Christian holidays further and further from their traditional timeframes. Historical documents confirm Copernicus' role in helping to correct the calendar, but there exists nothing more specific.
Sobel concludes that, "He held off publishing his theory for so long that when his great book, 'On the Revolutions of the Heavenly Spheres', finally appeared in print, its author breathed his last. Copernicus never heard any of the criticism, or acclaim, that attended 'On the Revolutions.' Decades after his death, when the first telescopic discoveries lent credence to his intuitions, the Holy Office of the Inquisition condemned his efforts...The philosophical conflict and change in perception that his ideas engendered are sometimes referred to as the Copernican Revolution."
Sobels' book is enjoyable. Her narrative approach to writing history addresses the nuanced details important in a serious work, while maintaining readability throughout. There are stretches of dry writing where Copernicus orbits the political, religious and military intrigue of Middle Ages Poland. This is a relatively minor complaint of Sobels' tightly written history. And don't fear the authors' fiction. It reads terrifically well while incorporating humor, history and believability.
