This volume in honour of Guido Clemente collects essays by nearly 40 established and younger scholars from all over the world, who want to express their gratitude for prof. Clemente’s direct or indirect teaching. While the essays included in the volume cover domains ranging from methodology and (the history of) historiography, over archaeology and epigraphy, to politics and religion, they are all held together by the main theme of the past as present. This is a prominent feature of Guido Clemente’s scholarly work: the awareness that from the last centuries of the Roman Republic up until Late Antiquity, the sense of the past as present marked the rhythm of everyday life and provided the key to understanding societal change.
