The "Legenda aurea", compiled in Latin by Jacobus de Voragine between 1260 and 1270, is the most widely disseminated collection of saints' legends in the Middle Ages. Among the countless vernacular reworkings there are three in Old Occitan which are closely bound up with the Catalan line of "Legenda aurea" adaptations. The Old Occitan Version B edited here for the first time represents a selection of 102 chapters from the original corpus with four additional chapters and is based on various Occitan and Catalan translations from the Latin. The linguistic commentary concentrates on the vocabulary of the texts edited and also presents it in a complete glossary. Newly attested forms and meanings are provided with commentaries of their own and represent a significant addition to the material available to Old Occitan lexicography.
