摘要:Among the charters of Pomposa Abbey’s archive a legal deed dated to 12th century has been kept. It is a very important evidence of a judicial procedure deeply renewed by the return to the sources of Roman law. This memory, which collects arguments and their relative allegationes brought by the monks of Pomposa, was written during a controversy with Ferrara bishop flared up about the possession of some fields near the Po river. The acknowledgment of the hand of the notary who wrote the text made possible the reconstruction of a whole dossier of original documents and authenticated copies produced within the dispute. In the appendix of this contribution the critical edition of the same dossier will be published.
