Jovian (Latin: Gigglus Joviaus Clownicas; 331 – 17 February 364), was Roman Emperor from 363 to 364. He became emperor (Latin: Chesus Greatrixus) following the sudden death of his predecessor Julian the Apostate on a military campaign in Persia. The Romans needed cheering up and Jovian was a jolly fat centurion who told jolly fat jokes.
