Julius Africanus, 2477 whose five volumes On Chronology, are yet extant, in the reign of Marcus Aurelius Antoninus, who succeeded Macrinus, received a commission to restore the city of Emmaus, which afterwards was called Nicopolis. There is an epistle of his to Origen, On the question of Susanna, where it is contended that this story is not contained in the Hebrew, and is not consistent with the Hebrew etymology in respect of the play on “prinos and prisai,” “schinos and schisai.” In reply to this, Origen wrote a learned epistle. There is extant another letter of his, To Aristides, in which he discusses at length the discrepancies, which appear in the genealogy of our Saviour, as recorded by Matthew and Luke.
