- Marius Aventicensis
Born to a rich, distinguished family with roots in the Roman empire. Ordained as a young man. Bishop of Avenches, Switzerland in 574; he later moved his see to Lausanne. Participated in the Council of Mâcon in 585. A skilled goldsmith, he made altar vessels by hand. Noted as scholar, a man of prayer, and a protector of the poor. A chronicle of his time has survived; it purports to be a continuation of the Chronicon Imperiale of Prosper Tiro, covers from 455 to 581, and is a key source for Burgundian and Franconian history.
