Valerian ( və-LEER-ee-ən; Latin: Publius Licinius Valerianus; c. 199 – 260 or 264) was Roman emperor from 253 to spring 260 AD. He rose to power during a particularly unstable period during the Crisis of the Third Century and appointed his son Gallienus as co-emperor.
Valerian is known as the first Roman emperor to have been taken captive in battle, captured by the Persian emperor Shapur I after the Battle of Edessa, causing shock and instability throughout the Roman Empire. The unprecedented event and rumors of his humiliation at the hands of the Persian emperor generated a variety of different reactions and "new narratives about the Roman Empire in diverse contexts".
