|Vetranio entered the army and served with distinction under the mighty Constantine I (AD 306-337), the first Christian ruler of Rome, who even during his lifetime came to be called "Magnus" -- The Great. Upon Constantine's death, the Roman Empire was split between his three surviving sons: Constantine II, Constantius II, and Constans. |
In 340 CE, sibling bloodletting eliminated Constantine II and the survivors divvied up the spoils, with the West going to Constans.
| In December of 350, Constantius marched west and met Vetranio at Naissus in modern Serbia. On Christmas day Vetranio formally abdicated the throne. Constantius pensioned him off to an opulent estate in Bithynia.|
Vetranio had played his difficult hand well, and enjoyed a better fate than most other men who claimed the top chair. Having two mints under his control, Siscia and Thessalonica, Vetranio struck coins both in his own name and that of Constantius II. His bronze coinage is scarce, the silver rare, the gold extremely rare.
