Denarius - Hadrian COS III, Neptune

The COS III designation anchors this issue to Hadrian's third consulship, a period when the emperor was actively consolidating his policy of fixed frontiers rather than further conquest — a deliberate break from Trajanic expansionism that shaped imperial ideology for the next generation. Neptune's prominence in Hadrianic coinage reflects practical politics as much as religion: Hadrian crossed the Mediterranean repeatedly during these years, and the fleet was a logistical backbone of his endless provincial tours.

RIC II.3 #790 is part of the extensive 2007 revision of the original Mattingly-Sydenham volume, which substantially reorganized Hadrianic types.
