Lupianus

Saint Lupianus of Rezé (in Latin Lupianus Ratiatensis, of Ratiatum) lived in the fourth century and is counted among the first Christians of the ancient city of Ratiatum and of the Pays de Retz. He was baptized by Saint Hilary of Poitiers, between 350 and 367, probably after Hilary's return from exile in Phrygia. Hilary is said to have come several times to Ratiatum, the second city of the Pictones, to visit the young Christian community there, and he then taught his disciple Lupianus, who died fairly soon.

His life is not well known, but Gregory of Tours devoted a chapter to him in the Glory of the Confessors in the sixth century. He is venerated in the Roman Catholic and the Orthodox Church. The day of his commemoration is not clear: according to some authors it could be 29 April or 1 July, according to others 11 October or 11 July. His veneration is attested by the chapel of Saint-⁠Lupien, built at Rezé on the site of his tomb. He should not be confused with Saint Louvent, a sixth-⁠century martyr of Champagne who also bears the name Lupianus, nor be called Lucian, as was sometimes mistakenly done.
