The seminar "Legal Commentaries: Between History and Theory" will take place at Adam Mickiewicz University in Poznań on 7–8 September 2026. Bringing together legal historians, canon law scholars, and legal theorists, the seminar will examine legal commentary as a historical form, an interpretative practice, and a contemporary legal genre. The contributions will range from early modern manuscript and print traditions to modern code commentaries, case-law commentaries, and analytical legal philosophy. The seminar is organised within the NCN-funded SONATA 18 project “EXTRA: The Decretals, Early Modern Science of Canon Law and Legal Commentaries Today”.
