Abstract
This paper intends to focus once again on the Roman legal document which is improperly called the “Edict of Milan”. The approach and arguments put forward here are not necessarily new or original. Nevertheless, it seems that this umpteenth return to this issue is useful, after several international scientific events were organised on the occasion of the supposed 1700th anniversary of the proclamation of this document by Constantine. We will see, in particular, that the title of edictum dates back to an error in translating from Greek to Latin. We will also be interested in the legal nature, as well as the historical significance and interest of the text that Eusebius of Caesarea and Lactantius have given us.
