Borders are approximate and debated. Frontier zones were not hard lines, and client kingdoms are not counted unless the source map includes them. Outlines for 133 BC, 44 BC, AD 14 and the later dates are rebuilt from the province outlines of AD 200, so early frontiers look more settled than they were. 264 BC and the Byzantine dates follow modern regional boundaries and are coarser still. 753 BC is a symbolic dot on Rome.
