This volume edited by Christine Ratkowitsch contains a selection of revised versions of some of the lectures delivered at the 8th International Medieval Latin Congress ("Medialatinitas", Vienna 2017). It aims to capture the intellectual program of the congress, the connection of Medieval Latin to other fields. The first three contributions are each dedicated – in chronological order – to one work of the Latin Middle Ages or Early Humanism and its respective relationship to ancient sources. Seven other contributions show the connection to Theology, Philosophy/Art History (Bernard of Clairvaux), Byzantine Studies, as well as German, Old French, English and Slavic Literature.
