Consentius was a learned man of senatorial rank, very likely living in Gaul and probably kin of or identical with one of the Narbonese Consentii in the circle of Sidonius Apollinaris. As internal cross-references show, his two extant works, De duabus partibus orationis nomine et verbo (GL 5.338-85) and De barbarismis et metaplasmis (GL 5.386-404; also edited by M. Niedermann [Neuchâtel 1937] and T. Mari [Oxford 2016]), were originally parts of a larger work, perhaps an ars on the model of Aelius Donatus, with whose ordering of the parts of speech and doctrine on the noun and verb Consentius agrees. But Consentius also freely elaborates beyond Donatus, and unlike the latter—who follows grammatical tradition in treating “barbarisms” among the vitia orationis, “metaplasms” among the virtutes orationis—Consentius joins them together, as two sides of the same coin, and—most unconventionally and importantly—draws his examples of “barbarisms” not from literary sources but from the spoken Latin of his own day.
