Brother of Gaulish Usurper – Jovinus
Sebastianus was the brother of Jovinus (411-413 AD) who was proclaimed Emperor at Mainz by Guntiarius, King of the Burgundians. Sebastianus was raised to the rank of Augustus by his brother to serve as the junior co-Emperor in 412 AD. Unfortunately, Sebastianus was killed in battle by Ataulf, King of the Visigoths, in 413 AD – a fate his brother would soon follow.
The coinage of Sebastianus is extremely rare. No denominations are known other than the typical reduced weight silver siliqua of the period.
