This is a critical edition of one of the many medieval French translations of Boethius' "Consolatio philosophiae". The base manuscript is Paris, Bibliothèque nationale, fr. 1096. The original text dates from ca. 1330 and was composed in the south of Lorraine. The Introduction examines the original dialect and that of each manuscript as well as some of the translation techniques adopted. It is a quite clear and accurate translation, with few omissions or additions. It was consulted by at least two subsequent translators of the "Consolatio". The philosophical and dialectal vocabulary presents a certain interest. The edition includes two glossaries, one relating to the edited text, the other to the vocabulary of the variants (three other manuscripts).
