Baring-Gould’s sources: Roman and Gallican Martyrologies. In Dempster's Scottish Menology on March 19 and Sept. 3. Authorities: — Two Lives, both long posterior, the second an amplification of the first, full of legendary matter, by Adso, Abbot of Moutier-en-Der, in the 10th cent.] Mansuetus of Toul was the first bishop of that see. It is pretended by his biographer, trusting to popular tradition, that he was consecrated and sent into Gaul by S. Peter. But what seems more probable is that he was long posterior. He is said to have been an Irishman (Scotus), and Dempster supposing that Scotus meant Scotchman, introduced him into his Scottish menology. If he were one of the many Irish missionaries who carried the light of the Gospel into Gaul and Germany and Switzerland, his date is later. The fables related of Mansuetus are many. The son of the prince of Toul fell into the river and was drowned; Mansuetus prayed, the boy came to the surface of the Moselle and revived, after having been under water a night and a day.

Nor were his miracles of restoring to life confined to boys. A native of Ireland (Scotus) lost his pig, which thieves had carried off, killed and eaten. He invoked S. Mansuetus, and made a pilgrimage to Toul to deplore the loss of his pig over the tomb of the saint. Great was his delight to find a pig on his way back, which he could appropriate and drive home to Ireland, under the assurance that it was his own pig.

In 1790 the relics [the bodily remains of a saint, or objects they used, kept with honor] of S. Mansuetus were divided among the canons of the church of Toul, that they might be preserved from the fury of the revolutionists. Many of the fragments have been restored, and the cathedral of Toul now possesses a shoulder, the church of S. Gengolf the head, that of S. Nicholas-de-Port a rib. The old crypt in which was the tomb of S. Mansuetus (in French Mansuy) is now private property. On the tomb he is represented trampling on paganism, with the resuscitated prince at his side.
