outside of the Kingdom of Poland. The first chancellor of the university was Piotr Wysz, and the first professors were Czechs, Germans and Poles, most of them trained at the Charles University in Prague. By 1520 Greek philology was introduced by Constanzo Claretti and Wenzel von Hirschberg; Hebrew was also taught. At this time, the Collegium Maius consisted of seven reading rooms, six of which were named for the great ancient scholars: Aristotle, Socrates, Plato, Galen, Ptolemy, and Pythagoras. Furthermore, it was during this period that the faculties of Law, Medicine, Theology, and Philosophy were established in their own premises; two of these buildings, the Collegium Iuridicum and Collegium Minus, survive to this day. The golden era of the University of Kraków took place during the Polish Renaissance, between 1500 and 1535, when it was attended by 3,215 students in the first decade of the 16th century, and it was in these years that the foundations for the Jagiellonian Library were set, which allowed for the addition of a library floor to the Collegium Maius. The library's original rooms in which all books were chained to their cases in order to prevent theft are no longer used as such. However, they are still occasionally open to hosting visiting lecturers' talks. As the university's popularity, along with that of the ever more provincial Kraków's, declined in later centuries, the number of students attending the university also fell and, as such, the attendance record set in the early 16th-century wasn't surpassed until the late 18th century. This phenomenon was recorded as part of a more general economic and political decline seen in the Polish–Lithuanian Commonwealth, which was suffering from the effects of poor governance and the policies of hostile neighbors at the time. In fact, despite a number of expansion projects during the late 18th century, many of the university's buildings had fallen into disrepair and were being used for a range of other purposes; in the university's archives, there is one entry which reads: 'Nobody lives in the building, nothing happens there. If the lecture halls underwent refurbishment they could be rented out to accommodate a laundry'. This period thus represents one of the darkest periods in the university's history and is almost certainly the one during which the closure of the institution seemed most imminent.
