Halfway through the first week, the group visited the Bardo Museum in western Tunis. The most beautiful mosaics of the Roman province of Africa are displayed there, providing a unique and almost breathtaking insight into Late Antiquity. The guided tour by a historian revealed the richness of these testimonies and especially the Christian testimonies, such as the famous “Mater Ecclesia” (“The church as/is mother”) mosaic from Tabarka (5th century): The mosaic is a funeral monument for a woman named “Valentia”, who may rest in peace (“in pace”). It shows a church building with the altar in the center. Here, “church” means both the community of believers and the building in which they gather.
