My paper aims to understand the function of the officia palatina by focusing specifically on their role as archives. The documentation, largely legislative, allows us to verify the material that was produced by the scrinia, but not to identify what was actually stored in them. Also, if perhaps, and we emphasize the perhaps, it is possible to have an idea of the material stored in the three "historical" scrinia - meaning those with the longest life, libellis, cognitionibus and i - it is more complicated to understand the role of the youngest but perhaps most important one, namely the scrinium memoriae, on whose functions questions still remain. The same questions that emerge on the competences of the magister memoriae. The purpose of this intervention is aimed at understanding what was stored in the scrinia, therefore what their role was in terms of archives. The most intuitive answer - but not for this the least true - is: what was functional to the government. On the basis of this assumption, we intend to propose some hypotheses on the archival function of the scrinium memoriae but also on the competences of the magister memoriae on which there are still no interpretative proposals.
