(Chronology, p. 334, [48]note 5.)

Here an invaluable work for comparison and reference must be consulted by the student; viz., the Chronicon of Julius Africanus, in Routh's Reliquiae (tom ii. p. 220, et seqq.), with learned annotations, in which (e.g., p. 491) Clement's work is cited. Africanus took up chronological science in the imperfect state where it was left by Clement, with whom he was partially contemporary; for he was Bishop of Emmaus in Palestine (called also Nicopolis), and composed his fine books of chronological history, under Marcus Aurelius. ¹ On the Alexandrian era consult a paragraph in Encyc. Britannica (vol. v. p. 714). It was adopted for Christian computation, after Africanus. See Eusebius (book vi. cap. 31), and compare (this volume, p. 85) what is said of Theophilus of Antioch, by Abp. Usher. ²
