Denarius - Hadrian P M TR P COS III, Bonus Eventus

Bonus Eventus — "Good Outcome" — was an ancient agricultural deity whose invocation on coinage carried pointed political weight. Hadrian's early reign required careful cultivation of senatorial goodwill after Trajan's death left several prominent senators executed under murky circumstances, and the appearance of propitious reverse types in 120–121 was part of a deliberate program to project benevolent, consensus-driven rule. The cos III dating pins this to Hadrian's third consulship, which he held from 119 onward but declined to renew after 120, an unusual act of ostentatious republican restraint.
