Catholic Encyclopedia (1913)/Rhodo
A Christian writer who flourished in the time of Commodus (180-92); he was a native of Asia who came to Rome where he was a pupil of Tatian's. He wrote several books, two of which are mentioned by Eusebius (Hist. eccl., V, xiii), viz., a treatise on "The Six Days of Creation" and a work against the Marcionites in which he dwelled upon the various opinions which divided them. Eusebius, upon whom we depend exclusively for our knowledge of Rhodo, quotes some passages from the latter work, in one of which an account is given of the Marcionite Apelles. St. Jerome (De vir. ill.) amplifies Eusebius's account somewhat by making Rhodo the author of a work against the Cataphrygians — probably he had in mind an anonymous work quoted by Eusebius a little later (op. cit., V, xvi).
