Cartulaire, I, item 232, 281-283.
A series of rules intended to deal with problems resulting from the relations between chaplains and canons in the choir. Several items refer to the physical space of the choir. For example, the dean is authorized to eject unauthorized chaplains and others who have entered the choir. "...Item, si inordinate se habeant ingressi chorum, decanus potest eos ejicere a choro sicut alios qui chorum ingrediuntur." Reference is also made to the candles in front of the crucifix "cereum arsurum ante ymaginem Crucifixi." Since the lower choir was under construction in these very years, this may be a provisional choir.
