Nicholas Copemicus (Nicolaus Copernicus) informs Albrecht, Duke of Prussia, that he has written a letter to John Benedict Solfa, doctor of the Polish King, with the question: in what way could he help George von Kunheim, the Duke's office-holder, in his illness. However, he has not received any news concerning this, which amazes him, so he intends to write again to Doctor John, and relay the answer without delay to the Duke.
