In short: Exiled by Emperor Domitian in 82 AD, Dio Chrysostom shed his status to live as a wandering Cynic. Armed only with two classic texts, he traversed the Roman frontier, eventually returning to influence the highest levels of power as a trusted advisor to the Emperor Trajan.

Born in Prusa around 40 AD, Dio Chrysostom was a prominent figure in the Roman province of Bithynia. He initially pursued a conventional path of local governance and rhetorical study, deeply influenced by Stoic and Platonist thought. However, his life took a dramatic turn in 82 AD when his criticism of Emperor Domitian led to his banishment from Italy and his home province. He claimed that, following guidance from the Delphic oracle, he adopted the life of a wandering beggar, carrying only a volume of Plato and a work by Demosthenes as he traveled through regions like Scythia and Thrace.

Following the murder of Domitian in 96 AD, Dio leveraged his influence with frontier military forces to support the rise of Nerva. This political alignment secured his return from exile and allowed him to adopt the name Cocceianus in honor of the new Emperor. In his later years, he became a significant public figure in Prusa, even engaging in local legal disputes regarding civic infrastructure as late as 111 AD. He likely passed away shortly thereafter, leaving behind a legacy as one of the most celebrated rhetoricians of the Second Sophistic school.

His surviving work, consisting of eighty orations, offers a window into the moral and political concerns of the era. These texts cover diverse themes, including the virtues required of a sovereign, the nature of freedom, and ethical living. His four Orations on Kingship, addressed to Trajan, demonstrate his transition from an exiled critic to a sophisticated political advisor who claimed an intimate understanding of the Emperor's character. While some of his writings were later misattributed or reassigned to other thinkers like Favorinus, his influence on ancient philosophy remains firmly established through his popular and wise approach to practical ethics.
