There is actually an objective reason for dating the provincial maps 125 or thereabouts it is at this time that the locations of most 80 auxiliary regiments are known as the majority of surviving military diplomas date from Hadrian s rule It s not entirely clear why By 180 most auxiliary troops had Roman citizenship all after 212 so diplomas which were certificates of citizenship were no longer issued Earlier it is possible that diplomas were normally issued in paper form unless the recipient specifically requested and paid for a metal one rather than as a metal tablet and so were eliminated by organic decomposition Also before 107 the empire did not include Dacia and so was not at its fullest extent ignoring the two year occupation of Mesopotamia under Trajan Of course the auxiliary issue is only relevant to the provincial maps where we would show the auxiliary regiments and not to the overall empire map where we don t Ideally we would have the same map as 125 for 30 BC Augustus start AD 14 Augustus end 54 Claudius end annexation of Britannia Thracia Mauretania 75 new Flavian legions 211 Severan legions and 284 loss of Dacia and Agri Decumates These maps would not take long to make as most of the details would be the same as the existing one the only substantially different one would be Augustus start 30 BC when the empire was much smaller If you can reproduce Goldsworthy s graphics using Inkscape then it really would be worth the effort to learn how to do it Because then we could produce some really attractive maps of all battles not just Strasbourg instead of the ugly line diagrams that we have to put up with now Your other projects look interesting I trust that they will all be physical maps I think we have traveled a long way from the useless political maps that you used to make Tuo Andrea
