Marijke Kooijman works as a doctoral student within the project ‘Lobbying in Late Antiquity’ of Prof. Dr. Lieve Van Hoof (Ghent University). Based on her formation as classicist, jurist and historian, she studies the letter collections of the Council of Chalcedon (AD 451) from a socio-legal as well as literary perspective. During her research stay in Bamberg (January – April 2021), she is focusing on the impact of these letters’ reception history on the interpretation of fifth-century diplomacy between East and West. Besides, she is comparing the functions and style of imperial and episcopal letter writing.
