martyr. She has been venerated at Rome since the 5th century and is mentioned in the Roman Canon. She died at Sirmium (Yugoslavia), notwithstanding her later Acta which make her a Roman martyr; her relics were translated to Constantinople. At Rome there was a church near the Circus Maximus called after its owner the titulus Anastasiae. Here the pope sang the second Mass on Christmas Day. Perhaps the Acta were written to satisfy curiosity about the origin of this church. Feast: 25 December, 22 December in the East.
