A committee has been set up under the auspices of the British Academy with the object of compiling a prosopography of the later Roman Empire (A.D. 284-641). Its object is to do for the later Empire what the Prosopographia Imperii Romani has done for the Principate, to provide the materials for the study of the governing class of the Empire. The majority of the entries will be persons holding official posts or rank together with their families, and the work will not include clerics except in so far as they come into the above categories.
