Fortunatus (18) , a bp. who has been confounded with Venantius Fortunatus, bp. of Poictiers. Born at Vercellae, he migrated into Gaul, and became intimate with St. Germanus, who induced him to write the Life of St. Marcellus. He was probably the author of bk. i. of the Life of St. Hilary of Poictiers, and of three other Lives of saints ascribed to his more distinguished namesake. He died at Celles, in the diocese of Sens, c. 569. Rivet, Hist. lit. de la France, t. iii. p. 298.
