Dioclesian
The prophetess Delphia predicts that the footsoldier Diocles will become emperor after killing a mighty boar and marry her niece Drusilla. Diocles kills Aper, whose name means boar, and becomes co-emperor, but abandons Drusilla for Princess Aurelia. Delphia disrupts the wedding and helps Rome’s enemies defeat the army. Diocles repents, defeats the invaders, yields half the throne to Maximian, and leaves with Drusilla.
