 Bishop Adalfredus (after 1031 – 1055) suffered many sleepless nights, worried about the number and behavior of his Canons and their hangers-on.Finally, exasperated, he acted.On 16 August 1045, citing decrees of the holy Fathers that in each Church clerics should be ordained in accordance with the ability of that church to support those clerics ministering at the altar, he issued a decree in which he limited the number of Canons in the Cathedral of Bologna to fifty.
