The Roman Empire
Diocletian, 284 – 305

From the late third century to the period of Diocletian up to Constantine the Great, portrait styles change dramatically. While the first coins issued for Diocletian and his eventual co-augustus Maximianus were still in line with the portraits of the military emperors seen in the decades before, the newly established tetrarchic structure of two Augusti and two Caesars called for completely different images. From this point on, the Tetrarchs are shown without individual portrait features. The tetrarchic 'One for all, all for one philosophy' included that the portraits of all four should look exactly the same. As a matter of fact, tetrarchic portrait types differ more between the many now established mints than between the tetrarchic emperors themselves.There are however a few exceptions: in some Western mints Maximianus shows a stubby nose, while his Caesar Constantius I is presented at times with a rather aquiline nose. These individual features can be best observed in issues from Treveri (modern Trier), where Constantius I resided. AMP.
