Evaristus (called Aristus in the Liberian Catalogue), bp. of Rome at the beginning of the 2nd cent. With respect to the exact date and duration of his episcopate, as well as the names and order of succession of his predecessors [See Linus; Cletus; Clement], ancient accounts are greatly at variance. Eusebius ( H. E. iii. 34, iv. 1) gives Clemens as his immediate predecessor, the third year of Trajan (101) as the date of his accession, and 9 years as the duration of his episcopate; but in his Chronicle he makes the latter 7 years ( Chron. iv. 1). Irenaeus, an older authority, who probably got his information when at Rome in the time of Eleutherus towards the end of the cent., also makes Clemens his predecessor, but gives no dates ( adv. Haeres. iii. 3, 3). The Liberian (a.d. 354) and subsequent Roman Catalogues, as well as Augustin and Optatus, represent him as succeeding Anacletus, and the former authorities give a.d. 96 as the commencement of his episcopate, and between 13 and 14 years as its duration. The best and probably final authority on the order and dates of the early era of Rome is Bp. Lightfoot's Apostolical Fathers , part i.
