Abstract
After defining the method of the research in progress at Redhis and summarizing the main results, three texts chosen from unpublished papyri were presented : the Institutes of the jurist Marcianus (P.Vindob. L 59 + L 92, 4th-5th century copy ) ; the first known copy of the Theodosian Code with a commentary in Greek, mentioning jurists (Berlin papyri, unpublished, in progress of publication by S. Ammirati and D. Mantovani : copy from the5th century) ; a fragment of Justinian's Digest (P.Berol. inv. 14081 : copy from the 6th century), which attests to the wide distribution of this anthology, a sign of uninterrupted familiarity with the works of classical jurists.
