Atto, cardinal priest of the titular church San Marco at Rome, compiled shortly after 1073 a breviary of canon law for his clerics. It is the first truly Roman collection of the century. Atto had been elected archbishop of Milan in 1072 by the Patarini faction, but he was not accepted by the imperialist and aristocratic factions and was forced to flee. He spent most of the rest of his life as cardinal at the church of San Marco. Apparently the Liber decretorum of Burchard was available to the clerics of his church, but Atto disapproved of its use because it contained apocryphal texts and because it contained canons from concilia trasmarina which, if at all authentic, were valid only locally. Only those canons have general validity, he said, which have been approved by the pope. Since his clerics were too poor to travel and had no one else to teach them, he felt obliged to provide them with a brief collection in which the texts of the canons were condensed.
The present analysis is based on the copy in the Ms Vat. lat. 586 (AM), which is the only surviving copy. The sources are the False Decretals and the letters of popes Gelasius I, Gregory I and Nicholas I. Conciliar canons from the Dionysio-Hadriana tradition are used, but are subordinate to the decretals. Series of the canons from the collection were used by Anselm of Lucca and Deusdedit and by Placidus of Nonantola for the Liber de honore ecclesie he composed circa 1111.
