Given the question: Read the following paragraph and extract the answer for the question: Whose successor created two additional hierarchical posts and added 16 more prebendary canons?  The dignitaries and canons constituted the chapter and had the primary role of aiding the bishop in the governance of the diocese. Often the bishop was the titular head of the chapter only and was excluded from its decision-making processes, the chapter being led by the dean as its superior. As the diocese of Moray based its constitution on that of Lincoln Cathedral, the bishop was allowed to participate within the chapter but only as an ordinary canon. Moray was not unique in this: the bishops of Aberdeen, Brechin, Caithness, Orkney and Ross were also canons in their own chapters. Each morning, the canons held a meeting in the chapterhouse where a chapter from the canonical rulebook of St Benedict was read before the business of the day was discussed. Bishop Brice's chapter of eight clerics consisted of the dean, precentor, treasurer, chancellor, archdeacon and three ordinary canons. His successor, Bishop Andrew de Moravia, greatly expanded the chapter to cater for the much-enlarged establishment by creating two additional hierarchical posts (succentor and subdean) and added 16 more prebendary canons. In total, 23 prebendaries had been created by the time of Andrew's death, and a further two were added just before the Scottish Reformation. Prebendary churches were at the bestowal of the bishop as the churches either were within the diocesan lands or had been granted to the bishop by a landowner as patronage. In the case of Elgin Cathedral, the de Moravia family, of which Bishop Andrew was a member, is noted as having the patronage of many churches given as prebends.Rural Deans, or deans of Christianity as they were known in the Scottish Church, supervised the priests in the deaneries and implemented the bishop's edicts. There were four deaneries in the Moray diocese—Elgin, Inverness, Strathspey and Strathbogie, and these provided the income not only for the cathedral and chapter but also for other religious houses within and outside the diocese. Many churches were allocated to support designated canons, and...
The answer is:
Bishop Brice's
