Saint Glycerius has been erroneously confused as the Glycerius (c. 420 - after 480), who was one of the last of the Western Roman Emperors (reigned 473-474), and who became bishop of Salona after his deposition. Accounts concerning the emperor's later life are mixed:
According to the chronicler Marcellinus Comes, "The Caesar Glycerius, who held the imperial power at Rome, was deposed from power at the port of Rome by Nepos, son of the sister of the former patrician Marcellinus. From Caesar he was ordained a bishop, and he died."
John of Antioch and Jordanes both write that Emperor Glycerius became bishop of Salona after Nepos took Rome, captured Glycerius without a fight and, having stripped him of royalty, appointed him to this see.
