Having begun my studies in mediaeval Roman law under Peter Stein's supervision it seemed to me appropriate to turn to that subject in offering a tribute to him. Jacques de Révigny taught in the Orléans law school from around 1260 to around 1280, and the importance of that law school in the thirteenth and early fourteenth centuries is now well established, particularly as a result of the work of E. M. Meijers. The work which he began in the University of Leiden has been continued there under the leadership of R. Feenstra and attention has focused on the writings of Jacques de Révigny, which, so far as they had been printed before Meijers brought out their importance, had been printed under the names of others – Pierre de Belleperche in the case of his commentary on the Code and Bartolus in the case of his commentary on the Institutes. The modest addition to what has since been achieved by way of publication of his writings which follows has been made possible by association with the Leiden project. I gratefully acknowledge the help which I have received from Leiden in preparing it.
