Issued after the third weight reduction at London. Maximian simply couldn’t kick the rebellious habit, and in 310 he pretended Constantine was dead and assumed the purple. Constantine quickly moved to quell the revolt and Maximian was compelled to commit suicide. Meanwhile, Constantine's propaganda war against Maxentius included proclaiming his descent from the victorious Claudius II and the adoption of Claudius’s patron god Sol Invictus, in opposition to Maxentius’s invocation of Mars.
