Struck in AD 287, this medallion commemorates the co-consulship between Diocletian and Maximian. Diocletian had actually elevated Maximian from the rank of Caesar to Augustus a year earlier after successful campaigns along the Rhine, defeating the Heruli and Chaibones and effectively clearing the Rhineland of Germanic tribesman. The timing of Maximian's elevation may have also been to assist with the increasing military threats from the new rebel Carausius, self-proclaimed ruler in Gaul and Britannia.
