At this time Africanus also, the author of the books entitled Cesti, was well known. A letter of his, written to Origen, is extant, in which he was at a loss whether the story of Susanna in the book of Daniel were a spurious and fabricated thing; to which Origen makes a very full reply.
Of the same Africanus there have also reached us five other works, his Chronographies, labours wrought with accuracy, in which he says that he himself made a journey to Alexandria because of the great fame of Heraclas, who, as we have shown, was greatly distinguished for philosophical studies and the other learning of the Greeks, and was entrusted with the episcopate of the church there.
And another letter of the same Africanus is extant, to Aristides, On the supposed discord between the genealogies of Christ in Matthew and Luke, in which he most clearly establishes the harmony of the evangelists from an account that came down to him, which in due season, by anticipation, I set forth in the first book of the present work.
