This meeting represents a first round table about the archives of Robert Marichal, in particular about the sections concerning Latin texts on papyrus which were investigated within the project PLATINUM. The lecturers focus on the usefulness of these archives for the study of Herculaneum papyri, the understaning of the relationship between Marichal and other European scholars, the history of Chartae Latinae Antiquiores and the identification or even edition of African Latin ostraca. At the end a digitalisation project of the archive is showed.
