But Kopernikus was neither Pole nor a polonized German nor a germanized Pole, HE WAS GERMAN!Read his signature again...he wouldn' call himself "german mathematician" if he would consider himself polish, now wouldn't he! Think!
Which might mean he [Kopernik] bracketed himself with Germans?! What do you think?
In middle agges being German or Polish had much different meaning. Political situation on Polish-German border.
en.wikipedia.org/wiki/Nikolaus_von_Renys
During the Battle of Grunwald in 1410, von Renys carried the banner of the Culmerland troops for the Teutonic Order, described in the Latin Banderia Prutenorum. Unwilling to fight against Poland, he lowered the banner, which was considered a signal for retreat that contributed to the defeat of the Knights.
en.wikipedia.org/wiki/Prussian_estates
Norman Housley noted that "The alienation of the Prussian Estates represented a massive political failure on the part of the Order". At first, the estates opposed Order more passively, by denying requests for additional taxes and support in Order wars with Poland; by 1440s Prussian estates would act openly, rebelling against the Order and siding with Poland militarily (see Lizard Union, Prussian Confederation and the Thirteen Years' War)
After horrible 20 century we like to watch movies about battles between east and west but in reality it was much different. It wasn't batte between races like some people would like to see.
Polish German contacts weren't always hostile.
en.wikipedia.org/wiki/Congress_of_Gniezno
In 1000 A.D, while on the pilgrimage, Otto III invested Duke Boleslaus I of Poland with the titles frater et cooperator Imperii ("Brother and Partner of the Empire") and populi Romani amicus et socius.
On the same visit, Otto III raised Gniezno to the rank of an archbishopric. Three new dioceses subordinate to Gniezno were created: the Bishopric of Kraków (assigned to bishop Poppo), Wrocław (assigned to bishop Johannes) and Kołobrzeg (assigned to bishop Reinbern). St. Adalbert's brother Radzim Gaudenty became the first archbishop of Gniezno.

I don't know what to think about it and I doubt in Bratwurst informations about this signature on documents to be true but I will check this data.
Now I will use Britanica:
