Alexander I., bp. of Rome, is stated by all the authorities to have been the successor of Evaristus. Eusebius (H. E. iv. 4) makes him succeed in A.D. 109, in his Chronicle, A. D. 111 (f. 89). He assigns him in both works a reign of ten years. He has been confused with a martyr of the same name, who is mentioned in a fragment of an inscription.
