Most agree he lived in the fifth century. Louis the Pious moved his remains in the Abbey of Neuwiller-lès-Saverne, in 826. He was canonized on 3 December 1049 by Pope Leo IX. He is commemorated in the Roman Martyrology on 29 August. References Further reading Henri Tribout de Morembert : Le Diocèse de Metz, Letouzey & Ané, Paris, 1970. Bishops of Metz
