Cronius is the name of two early Christians:
1. An ecclesiastic who accompanied Athanasius tot Tyre, and signed his letter to the church of that place (Athan. ad Constant. 1:797); perhaps the same as the bishop of Metole in the list given by Meletius (ibid. 789).
2. A presbyter and solitary, visited by Palladius A.D. 394 (who was afterwards bishop of Helenopolis in Bithynia), and about the same time by Petronius (afterwards bishop of Boulogne, and canonized). He was a disciple and interpreter to St. Anthony, and lived in the deserts of Egypt. He was canonized (Pallad. Hist. Laus. cap. 7, § 713; De Vitis Patrum, 7, cap. 19, ap. Migne, Patrol. Lat. 73:1041, 1122, 1126; Ceillier, 7:485; 10:161).
