Which early play did Henrik Ibsen write while preparing for university?

The early play that Henrik Ibsen wrote while studying for his university entrance examinations was titled Catilina (1850), or Catiline in English.1

Although Ibsen was working as an apothecary’s apprentice in Grimstad at the time, he dedicated his limited leisure hours to writing this work, which was inspired by the Latin texts he was required to study for his exams. While the play was not considered a major success, it introduced recurring themes—such as the rebellious hero—that would define his later career in dramatic literature.12
