The first is April 14, Tiburtius (a Roman martyr).

The persons intended by the other names are more uncertain); Dec. 27, natale of St John, Evangelist; Dec. 28, natale of the Innocents.
It has been thought well to give in full this list, defective though it is (as lacking the opening months of the year). It exhibits indeed a large preponderance of celebrations of local interest; but there are clear indications that already the martyrs of other places than Rome are securing themselves positions in the Roman Kalendar.
The collection of masses and other liturgical offices known as the Gelasian Sacramentary are not without interest in illustrating the development of the Kalendar, more particularly among the Franks. But we pass on to consider the features of the distinctively Roman service book, which, by a somewhat misleading name, has been called the Gregorian Sacramentary. In its present form (though it contains many ancient elements) it is probably not earlier than the close of the eighth century. Omitting notices of moveable days, and exhibiting the dates by the days of the month in our modern fashion, the Kalendar runs as follows[38], some remarks being added within marks of parenthesis.
January. 1. Octava Domini (the octave of Christmas). 6. Epiphania (called in the older Roman Kalendar ‘Theophania,’ as by the Greeks). 14. St Felix ‘in Pincis’ (on the Pincian). 16. St Marcellus, Pope. 18. St Prisca (at Rome). 20. SS. Fabian and Sebastian (both at Rome). 21. St Agnes (at Rome)[39]. 22. St Vincent (Spain). 28. Second of St Agnes (Octave).
February. 2. Ypapante, or Purification of St Mary. 5. St Agatha (Sicily: a church at Rome dedicated to her). 14. St Valentine (presbyter at Rome).
March. 12. St Gregory, Pope. 25. Annunciation of St Mary.
April. 14. SS. Tiburtius and Valerian (at Rome). 23. St George (Eastern: church ‘in Velabro’ at Rome). 28. St Vitalis (of Ravenna: a church at Rome).
May. 1. SS. Philip and James, Apostles. 3. SS. Alexander, Eventius and Theodulus (Pope, and two presbyters at Rome). 6. Natale of St John before the Latin gate (Rome). 10. SS. Gordian and Epimachus (both at Rome). 12. St Pancratius (at Rome, where a church was dedicated to him). 13. Natale of St Mary ‘ad Martyres’ (dedication of the Pantheon at Rome by Boniface IV). 25. St Urban, Pope.
June. 1. Dedication of the Basilica of St Nicomedes (at Rome). 2. SS. Marcellinus and Peter (at Rome: a church in their honour is said to have been erected by the Emperor Constantine on the Via Lavicana). 18. SS. Marcus and Marcellianus (both at Rome). 19. SS. Protasius and Gervasius (Milan). 24. Natale of St John Baptist. 26. SS. John and Paul (two brothers at Rome). 28. St Leo, Pope. 29. Natale of SS. Peter and Paul, Apostles (Rome). 30.
