This volume is the first study of the influence of Roman law on the first written law of Iceland. Starting with a presentation of the legislation during the period of the Icelandic free state, Hafliði Másson is presented in detail. Through him influences from Roman law, as well as norms from the Old Testament played a part in the legal codex of Grágás. The work is thus of significance for legal history as well as for German and Byzantine studies.
