Many interesting details of the Feast of Boys, as it was celebrated in France, are contained in various ceremonial books. The _Officium Infantum_ of Rouen may be taken as typical[1202]. After second Vespers on St. John’s day the boys marched out of the vestry, two by two, with their ‘bishop,’ singing _Centum quadraginta_. There was a procession to the altar of the Holy Innocents, and _Hi empti sunt_ was sung[1203]. Then the ‘bishop’ gave the Benediction. The feast of the following day was ‘double,’ but the boys might make it ‘triple,’ if they would. There was a procession, with the _Centum quadraginta_, at Matins. At Mass, the boys led the choir. At Vespers the _baculus_ was handed over, while the _Deposuit potentes_ was being sung[1204]. At Bayeux the feast followed the same general lines, but the procession at first Vespers was to the altar, not of the Holy Innocents, but of St. Nicholas[1205]. Precise directions are given as to the functions of the ‘bishop.’ He is to wear a silk tunic and cope, and to have a mitre and pastoral staff, but not a ring. The boys are to do him the same reverence that is done to the real bishop. There are also to be a boy _cantor_ and a boy ‘chaplain.’ The ‘bishop’ is to perform the duties of a priest, so long as the feast lasts, except in the Mass. He is to give the benediction after _Benedicamus_ at first Vespers. Then the boys are to take the higher stalls, and to keep them throughout the following day, the ‘bishop’ sitting in the dean’s chair. The boys are to say Compline as they will. The ‘bishop’ is to be solemnly conducted home with the prose _Sedentem_, and on the following day he is to be similarly conducted both to and from service. At Mass he is to cense and be censed like the ‘great bishop’ on solemn occasions. He is also to give the benediction at Mass. There is a minute description of the ceremony of _Deposuit_, from which it is clear that, at Bayeux at least, the handing over of the _baculus_ was from an incoming to an outgoing ‘bishop,’ to whom the former was in turn to act as ‘chaplain[1206].’ The rubrics of the Coutances feast are even more minute[1207]. The proceedings began after Matins on St. John’s day, when the boys drew up a _tabula_ appointing their superiors to the minor offices of the coming feast. This, however, they were to do without impertinence[1208]. The vesting of the ‘bishop’ and the Vespers procession are exactly described. As at Bayeux the boys take the high stalls for Compline. The canon who holds a particular prebend is bound to carry the candle and the _collectarium_ for the ‘bishop.’ After Compline the ‘bishop’ is led home with _Laetabundus_, but not in pontificals. Throughout the services of the following day the ‘bishop’ plays his part, and when Vespers comes gives way to a ‘bishop’-elect at the _Deposuit_[1209]. The ‘bishop’ of St. Martin of Tours was installed in the neighbouring convent of Beaumont, whither all the _clericuli_ rode for the purpose after Prime on St.
