Gioviano Cepanico

Jovian, surnamed Hypatus or Ceparius, was Byzantine magister militum per Venetiae in charge of the duchy of Venice in 740. Following the murder of the doge Orso Ipato in 737, the Exarch of Ravenna imposed administration by annual magistri militum on Venice who replaced the doge. Jovian was the fourth of these officials. This period of government by magistri militum lasted until 742, when the fifth and last of such officials was deposed and the dogeship was restored.
