This example found imitators without there being any legislation on the point. Other Orders speedily took it up, such as the Benedictines and Carthusians, etc.;[695] but it was longer before the secular clergy adopted this practice in each diocese. The date of its introduction varies greatly in different countries; it will be sufficient for us to give a few dates for which we have certain information, which have a special interest for us. The first diocese to adopt All Souls’ Day seems to have been Liège, where it was introduced by Bishop Notker († 1008).[696] It appears in the martyrology of Besançon, called after Bishop Protadius, and compiled between 1053 and 1066; it is mentioned in the fourteenth of the Roman Ordos, which belongs to the thirteenth century; it is not found in the Cologne Calendar of the same century, nor in the more ancient one published by Binterim; it is also absent from a calendar put out in 1382.[697] We have more detailed information respecting the Church of Milan. Bishop Otricus (1120-1125) had already introduced the observance of All Souls’ Day, but placed it on the day following the dedication of the cathedral, _i.e._ the 15th October. This arrangement continued to the time of St Charles Borromeo, who in 1582 adopted the Roman, or rather the original date.[698] In the Greek and Russian Churches the commemoration of the departed is kept on the Saturday before the Sunday “Apoecros,” which corresponds to our Septuagesima Sunday. The Armenians keep it on Easter Monday. 13. _The Festivals of the Angels_ The existence of higher and purely spiritual beings formed part of the religious belief of the Jews; they are mentioned in countless passages of the Old Testament, but no worship was paid directly to them by the Synagogue. In the Christian Church the cultus of the angels, especially of St Michael, can be traced back to remote antiquity. In more recent times special days have been set apart in honour of the other two angels named in the Holy Scriptures, and also of the Guardian Angels; St Gabriel is honoured on the 18th March, St Raphael on the 24th October.
