It is well known that the custom of the ancient Church was not to celebrate the festivals of martyrs and other saints during Lent, which rule the Spanish Church followed even with regard to this feast. But in Constantinople an exception was made in its favour, which was expressly approved by the fifty-second canon of the Trullan Council. The feast is absent from the ancient Gallican Missal and the Lectionary of Luxeuil, but in Rome, according to the evidence afforded by the _Gelasianum_ and _Gregorianum_, the feast was observed on the same date as in the East. The feast of our Lady in Advent (S. Mariæ), noted, without further specification, in the Lectionary of Silos dating from about 650, can be no other than the Annunciation. Soon afterwards, however, the tenth Council of Toledo (656) took occasion to remark upon the difference of date. External influences (_traducti homines_) had been the cause. The Council decided in favour of the date hitherto observed in Spain, and ordained in its first canon that the feast should be celebrated throughout Spain eight days before Christmas—on the 18th December. But in the East the other date was already so widely observed that it was even employed as a fixed indication of time, as, for example, when the Alexandrian Paschal Chronicle states in 624 that Heraclius and his forces started for the East on the day of Mary’s Annunciation.[505] This, along with other indications, shows that in the East the festival had been earlier adopted and was widely spread. A circumstance of special importance is that the schismatic Armenians, whose ecclesiastical year in other respects is very primitive in character, observe this feast. They keep it, however, on the 7th April. This is due to the fact that they have not adopted Christmas, and still celebrate the birth of Christ in the ancient manner on the 6th January. Counting back nine months from this date one arrives at the 7th April. The Armenians certainly celebrated this festival before their separation from the Church. It was known and loved in the East as early as the fifth century, as the sermons of Proclus, Patriarch of Constantinople († 446), and of Peter Chrysologus of Ravenna († 450), prove.[506] Both methods of dating the festival existed side by side for a long period. The majority was in favour of the 25th March, but the other date was not without supporters, especially in Upper Italy, for according to the Milanese rite the _Annuntiatio_ falls in Advent, and, indeed, on the fourth Sunday. In southern France the difference in date gave rise to sundry differences and disputes which terminated in a victory for the Roman usage. Certain Spanish monks, who came to Cluny under Abbot Odilo, desired to celebrate the festival after their own fashion, which was at first allowed them. In the eleventh century several Councils occupied themselves with the question, and decided, obviously out of regard for Rome, for the 25th March.[507]
