Nostradamus
When he was 14, Nostradamus succesfully passed the test and was accepted to attend the University of Avignon. He attended the university to study for his baccalauréat. In the university, he studied trivium, rhetoric, and logic, rather than something more advanced. It was only later in time, that universities had studies more advanced, such as quadrivium, astronomy, and astrology. He only studied in the university for more than one year, when the university closed due to a plague outbreak. All of the inhabitants of Avignon were forced to leave. According to Nostradamus' journals, as a result of the plague outbreak, after he left Avignon, he escaped to the countryside for 8 years, where he worked as a medical researcher starting from 1521. By 1529, when Nostradamus was already a apothecary for some years, he successfully passed the test and was accepted to enter the University of Montpelier to study for a doctorate in medicine, but shortly after his attendance, he was expelled by the student procurator, Guillaume Rondelet, when it was discovered he worked as a apothecary. Back in the day, apothecaries were banned from attending universities in France because it was considered a "manual trade" and had been slandering physicians. The explosion document still exists in the university's library. Some of his publishers and correspondents would later call him a "doctor". After his explusion, Nostradamus still continued working, though it is disputed whether he was still a apothecary (after he got expelled), and succesfully invented a "rose pill". Some people believe that the pill was used to protect people from the plague.
