Nawojka (pronounced: [naˈvɔi̯ka]; 14th-century – 15th-century) was a medieval Polish woman known to have dressed as a boy in order to study at the University of Kraków in the 15th century.
Nawojka successfully fooled everyone and studied for two years, making herself a name as a great scholar and a serious student.
According to a possibly later addition to the story, she was offered work as a domestic assistant to one of the professors, but declined: at the time servants were expected to accompany their masters to the public bath.
The versions differ here again: according to one, two soldiers wagered that the student walking by was in fact a woman, and exposed her; according to the second, she was found by a son of wójt from Gniezno who joined the school; according to the third one, she fell ill and a doctor examining her found out the truth.
When she was brought before the authorities to explain why she had disguised her gender, she simply answered: "For the will of learning".
