Martyrdom of Pionius
The Martyrdom of Pionius (Greek: Πιόνιος) is an account dating from about 250 AD to 300 AD of the martyrdom of a Christian from Smyrna named Pionius. It is also known as The Martyrdom of Pionius the Presbyter and His Companions, The Acts of Pionius, and in Latin as Martyrium Pionii or Passio Pionii. Pionius was a presbyter, and was most likely killed between 249 and 251 AD during the rule of the Roman Emperor Decius. The feast day of Saint Pionius is kept on March 11 in Eastern Orthodox churches, and on February 1 in Roman Catholicism.
