Bologna University is one of the oldest universities in Europe, and Bologna is a historic city in northern Italy. 1088, Bologna began to establish a university, nearly four centuries ago.
Poles studied in the University of Bologna for three centuries, and Copernicus's uncle got his doctorate in this university.
In the era of Copernicus' life, it has become a common thing that many well-off people would cross the Alps and go all the way to Italy for further study.
During his stay at Bologna University, Copernicus grew a beard and wore secular clothes. He also has a special school uniform, which is a dark robe and hat. Copernicus didn't like such clothes. He only wears this uniform when attending grand religious ceremonies.
