 Faced with Shapur 's third campaign , the Roman emperor Valerian marched against the Persian monarch but was defeated near Edessa in late spring 260 and taken as a prisoner . The Persian emperor then ravaged Cappadocia , Cilicia and claimed to have captured Antioch , the metropolis of Syria . Taking advantage of the situation , Fulvius Macrianus , the commander of the imperial treasury , declared his sons Quietus and Macrianus Minor as joint emperors in August 260 opposing Valerian 's son Gallienus . Fulvius Macrianus took Antioch as his center and organized the resistance against Shapur ; he dispatched Balista , his praetorian prefect , to Anatolia . Shapur was defeated in the region of Sebaste at Pompeiopolis prompting the Persians to evacuate Cilicia while Balista went back to Antioch . Balista 's victory was only partial , as Shapur withdrew east of Cilicia where the marauding Persian units continued to occupy the area , while a Persian force took advantage of Balista 's return to Syria and headed further west in Anatolia .
