Chronicle of Marius of Avenches

Eo anno iterum Langobardi in Vallem ingressi sunt et Clusas obtinuerunt et in monasterium sanctorum Acaunensium diebus multis habitaverunt: et postea in Baccis pugnam contra exercitum Francorum commiserunt, ubi paene ad integrum interfecti sunt, pauci fuga liberati.

'In this year, the Lombards again invaded Valais and took possession of Clusae. They lived in the monastery of the saints of Agaune for many days, and afterwards engaged the army of the Franks in battle at Bex, where they were killed almost to a man; a few escaped by flight.'

Marius, bishop of Avenches c. 574-c. 594, composed a short continuation of the chronicle of Prosper of Aquitaine, covering events from the end of Prosper's chronicle in 455 up to 581.


The reputed site of the martyrdom of Mauritius and the Theban Legion was at Acaunum in the upper Rhone Valley (present day Saint-Maurice-d'Agaune, Switzerland). The monastery there was founded by Sigismund, king of the Burgundians, in 515. This entry in the chronicle of Marius of Avenches is the clearest account of the occupation of the monastery during the Lombard incursion into Francia in 574. This is the event mentioned in the Copenhagen continuation of Prosper (E03573) and the chronicle of Fredegar (E05956).
