The unity of history connects occurred and reflected history around the central concept of Historia in all languages of the Latin world, and this within the continuity of their literary genres. These also include the non-historical documentation of events in epic, legend, and fable, from which experienced history can be very concretely drawn, even reconstructed. All elements of this one history are now understood again in European fullness, after overcoming national limitations. This volume brings together works by Karl Ferdinand Werner that provide examples of this richness and have contributed to that reinterpretation. Contents: Werner Paravicini: Foreword I.
