 The first one to compile and systematize the previous universal council canons was Graciano, a bolognian theology teacher, who wrote ca.1140 his "Concordance of the Discordances of the Canons", commonly called "Decree".The work of Graciano did not have official status, but it reached great prestige and caused in the following decades a height in legal consultations formulated to the pontiff s, something to be expected at a time of insufficient organization of the civil power.
