A new codex fragment produced in lyon in around ad 900, which transmits the anonymous «vita et passio sancti desiderii episcopi et martyris»

Identification of a new manuscript of the Vita et passio sancti Desiderii episcopi et martyris written by an anonymous merovingian monk, probably copied at Lyon around the year 900. It is a small fragment, now the oldest surviving manuscript of the life of Saint Desiderius of Vienne, served at the Arxiu de la Catedral de la Seu d’Urgell. The authors belive that this anonymous version is older than the Vita sancti Desiderii written by the Sisebut, King of the Visigoths, although its last part was added in a second moment.
