ANTERUS, an'te-rus: Bishop of Rome in the third century, successor of Pontianus. According to the Catalogus Liberianus, he was consecrated Nov. 21, 235. The divergent account of Eusebius (Hist. eccl., VI. xxix. 1), which makes him enter upon his office in the reign of Gordianus, is of less authority. After a pontificate of little over a month, he died Jan. 3, 236. The stone placed over his grave in the cemetery of Calixtus was discovered in 1854.
