Baring-Gould’s sources: Gallican Martyrologies. Authority': — The lections in the Le Mans Breviary.] S. Innocent was a native of Le Mans; he was baptized, educated, and ordained by S. Victorius. He succeeded S. Principius in the see of Le Mans, and was a model of virtue and prudence during his long episcopate of forty-six years. He greatly loved those who led the life of retirement from the world, and rejoiced to see the wastes and wildernesses in his diocese thronged with hermits. He gave many of them places where to dwell, and he directed them in their manner of life. Many of his disciples became famous; such were SS. Carilef, Ulface, Rigomer, Constantian, Frambald and Leonard.

He died on the feast of SS. Gervase and Protasius in 542, and was buried in the church dedicated to these saints which had been built on the further bank of the Sarthe, to contain their relics [the bodily remains of a saint, or objects they used, kept with honor], given by S. Martin of Tours to the church of Le Mans.
