Watch List notes:

The Roman Empire
Trajan, 98-117

The earliest portrait types of Trajan resemble those of Nerva, a phenomenon that can be seen across all adoptive emperors. He soon develops his own portrait types, first massive and with a fierce look, then mainly noble imperial types with busts. AMP.
