Ruling during the Crisis of the Third Century that nearly caused the collapse of the empire, he repelled wave after wave of barbarian invaders, but he was unable to prevent the secession of important provinces. Gallienus presided over a late flowering of Roman culture, patronizing poets, artists, and philosophers. He was assassinated by his own soldiers in 268 while besieging Milan. |
