In page Anastasia of Sirmium:

"

At all events, the insertion of her name into the Roman Canon of the Mass towards the end of the 5th century show that she then occupied a unique position among the saints publicly venerated at Rome. Thenceforth, the church on the Palatine is known as "titulus sanctae Anastasiae" and the martyr of Sirmium became the titular saint of the old 4th-century basilica. Evidently because of its position as titular church of the district (including the imperial dwellings on the Palatine), this church long maintained an eminent rank among the churches of Rome; only two churches preceded it in honour: St. John Lateran, the mother church of Rome and seat of the Pope, and Santa Maria Maggiore. This ancient sanctuary stands today quite isolated amid the ruins of Rome.[citation needed]
