is the name of several persons in early Christian records:
1. A ponitiff of Thrace in A.D. 304 (Tillemont, Memoires, 5, 305). (See PHILIP OF HERACLEA).
2. The persecutor of Eulalia (q.v.) is called by this name in some copies of her acts, in others Datian (Tillemont, 5, 322).
3. Supposed by Tillemont (7, 632) to have been an Apollinarist, and companion of Timotheus, and, on receipt of a letter from him, to have written to others of the same sect named Pausorius, Uranius, Diodorus, and Jovius. But from the passage to which he refers (Leontius Byz., adv. Fraud. Apollin, in Migne, Patr. Gr. 89, 1954), it appears rather that Cataphronius was an imaginary personage in a dialogue dedicated by Timotheus to Pausorius and others.
4. The praefect of Egypt in A.D. 356, who established the Arian bishop George at Alexandria, and persecuted the Catholics (Tillemont, 8, 157, 677; Athanas. 1, 847).
