King Sigismund circulated this valuable book by Copernicus among all the courts of Europe, and it need not be stated that the suggestions made by Copernicus have been adopted by civilized nations everywhere. * * * * * The humdrum duties of a country clergyman did not still the intense longing of Copernicus to know and understand the truth. He visited the sick, closed the eyes of the dying, kept his parish register, but his heart was in mathematics, and so there is shown at Thorn an old church register kept by Copernicus, where, in the back, are great rows of figures put down by the Master as he worked at some astronomical problem. In the upper floor of the barn, back of the old dilapidated farmhouse where he lived for forty years, he cut holes in the roof, and also apertures in the sides of the building, through which he watched the movements of the stars. He lived in practical isolation and exile, for the Church had forbidden him to speak in public except upon themes that the Holy Fathers in their wisdom had authorized. None was to invite him to speak, read his writings or hold converse with him, except on strictly church matters. Copernicus knew the situation--he was a watched man. For him there was no preferment: he knew too much! As long as he kept near home and did his priestly work, all was well; but a trace of ambition or heresy, and he would be dealt with. The Universities and all prominent Churchmen were secretly ordered to leave Copernicus and his vagaries severely alone. But the stars were his companions--they came out for him nightly and moved in majesty across the sky. "They do me great honor," he said; "I am forbidden to converse with great men, but God has ordered for me a procession." When the whole town slept, Copernicus watched the heavens, and made minute records of his observations. He had brought with him from Rome copies made by himself from the works of the prominent Greek astronomers, and the "Almagest" of Ptolemy he knew by heart. He digested all that had been written on the subject of astronomy; slowly and patiently he tested every hypothesis with his rude and improvised instruments. "Surely God will not damn me for wanting to know the truth about His glorious works," he used to say. Emerson once wrote this: "If the stars came out but once in a thousand years, how men would adore!" But before he had written this, Copernicus had said: "To look up at the sky, and behold the wondrous works of God, must make a man bow his head and heart in silence. I have thought and studied, and worked for years, and I know so little--all I can do is to adore when I behold this unfailing regularity, this miraculous balance and perfect adaptation. The majesty of it all humbles me to the dust."
