Once known as Kraków Academy, Jagiellonian University is the oldest university in Poland and one of the oldest in Europe. Established in 1364 by King Casimir III, the university has educated such greats as astronomer Nicolaus Copernicus and poet Jan Kochanowski. PAP, Science and Scholarship in Poland, has a feature on the anniversary.
From the article:
The fifteenth century and the beginning of the sixteenth are the golden age of Kraków Academy. Its reputation attracted students from all over Europe. Approximately 44 percent of all students were foreigners. It was the period of renaissance of mathematical, astronomical and geographical sciences. Copernicus created heliocentric theory, and Maciej Miechowita published the "Tractatus de duabus Sarmatiis…", the first systematic description of the lands between the Vistula, the Don and the Caspian Sea. The introduction of teaching Greek and Hebrew languages was a sensation on the European scale.
