So far the growth of the Kalendar was the outcome of natural and spontaneous feeling. But at a later time we have manifest indications of artificial constructiveness, the laboured studies of the cloister, and the work of professional martyrologists and Kalendar-makers. To take, for the purpose of illustration, an extreme case, it is obvious that the assignment of days in the Kalendar of the Eastern Church to Trophimus, Sosipater and Erastus, Philemon and Archippus, Onesimus, Agabus, Rufus, Asyncretus, Phlegon, Hermas, the woman of Samaria (to whom the name Photina was given), and other persons whose names occur in the New Testament, is the outcome of deliberate and elaborate constructiveness. The same is true of the days of Old Testament Patriarchs and Prophets, once, in a measure, a feature of Western, as they are still of Eastern Kalendars. But even all the festivals of our Lord, save the Pascha, though doubtless suggested by a spontaneous feeling of reverence, could be assigned to particular days of the year only after some processes of investigation and inference, or of conjecture. Whether the birthday of the Founder of the Christian religion should be placed on January 6 or on December 25 was a matter of debate and argument. Commentators on the history of the Gospels, the conjectures of interpreters of Old Testament prophecy, and such information as might be fancied to be derivable from ancient annals, had of necessity to be considered. The assignment of the feast of the Nativity to a particular day was a product of the reflective and constructive spirit. It is not absolutely impossible that ancient tradition, if not actual record, may be the source of June 29 being assigned for the martyrdom of St Peter and St Paul; but a more probable origin of the date is that it marks the translation of relics. Certainly the days of most of the Apostles (considered as the days of their martyrdoms) have little or no support from sources that have any claim to be regarded as historical. They find their places but gradually, and, it would seem, as the result of a resolve that none of them should be forgotten.
