Although there were several attempts to revive the university, it functioned only as a "paper university", granting degrees without teaching. In 1601, the university was finally reopened by Ranuccio I Farnese, and the papal bull was given. It was a joint institution with a Society of Jesus, and a third of staff were teachers from a local Jesuit school, who taught in a separate building and by Jesuit curriculum. There were usually about 27–32 teachers and 300–400 students in the 17th century.
