Hi I just read the debate on the map and I would like to make a point. That on the Roman Empire article, the maximum extent of the Empire includes Trajan's temporary holdings in the East including Mesopotamia. These territories were held for just a year before being returned to Parthia yet they are clearly shown in many good encyclopaedias and reference books hence the arguement that lines (which is in my opinion short because they occupied Pataliputra not just get stopped near it) are more than adequate doesn't hold much strength in the face of this considering the Greek hold on Pataliputra was about 8 years.
