Sidonius Apollinaris (1. v. Epist. 9, p. 139, and Not.

Yet the praefect supported a respectable character in the world, and even in the church; held a devout correspondence with St. Augustin and St. Jerom; and was complimented by the latter (tom. iii. p. 66) with the epithets of Christianorum Nobilissime and Nobilium Christianissime .
