Stephen of Nicaea was a 4th-century Christian bishop who served as the first leader of the church in Reggio Calabria. Born in Nicaea around 300, he is traditionally believed to have traveled to Italy alongside the Apostle Paul. According to this legend, Paul appointed him to his episcopal position in Rhegium. Although some accounts link his death to the reign of Nero, historical analysis suggests he may have been martyred during the persecutions under Emperor Diocletian.
