Among the African rhetor Marius Victorinus’s anti-Arian works are two letters to him from an otherwise unknown Arian named Candidus: in the first, Candidus expounds Arian doctrine on the basis of Platonic philosophy; in the second he sends Victorinus the texts, in Latin, of two letters by Arius and Eusebius of Nicomedia. Various modern scholars think that Candidus was a literary fiction of Victorinus, who used him to present his refutation of Arian doctrine more clearly and effectively.
