The Collection of Anselm of Lucca (1081-1083), which was named by Cardinal Alphons M. Stickler ‘the best Gregorian work’ comprises papal letters, conciliar canons, patristic material and Roman law texts. The text analysis of twelfth century manuscripts has been improved by the understanding of the origin of this collection’s recensions, which constituted the instruction at the cathedral school. Prof. Manlio Bellomo’s opinion looks upon the traditional idea of the ‘intact literary work’ as an exploded idea with regard to the written works of the university instruction system. This opinion can also be affirmed regarding Anselm’s Collection.
