Second was the constitution of a cathedral body. This was framed on the usual Norman model, with dean, precentor, chancellor, and treasurer, whose duties were exactly defined, some thirty-two canons, a subdean, and succentor. All save the last two were bound to residence. These canons were ""secular,"" each living in his own house. Their duties were to be special companions and advisers of the bishop, to carry out with fitting solemnity the full round of liturgical services and to do missionary work in the surrounding districts. There was formed a school for clergy of which the chancellor was the head. The cathedral was thoroughly constituted ""the Mother Church"" of the diocese, ""a city set on a hill"". Osmund's canons were renowned for their musical talent and their zeal for learning, and had great influence on the foundation of other cathedral bodies.
