P. Licinius Egnatius Gallienus, son of Valerian I, was made co-emperor in AD 253. Gallienus was responsible for affairs in the West and made his headquarters in Gaul. On the capture of his father by the Persians in AD 260 Gallienus became sole ruler. Having dealt with the ensuing revolts of Postumus, Ingenuus and Regalianus, he restored imperial control and suppressed subsequent revolts by the Macriani. Gallienus also supervised military reforms and was reponsible for many victories in the East. A conspiracy of senior officers led to his assassination in AD 268 while he was dealing with the rebellion of Aureolus and Postumus. The antoninianus above was struck at Rome after AD 260. The obverse depicts Gallienus as sole ruler. The reverse shows the sun-god Sol, also a god of victory, as divine protector of the emperor - a common feature of coinage in the later third century.
