1. At this time also Africanus, the writer of the books entitled Cesti, was well known. There is extant an epistle of his to Origen, expressing doubts of the story of Susannah in Daniel, as being spurious and fictitious. Origen answered this very fully.
2. Other works of the same Africanus which have reached us are his five books on Chronology, a work accurately and laboriously prepared. He says in this that he went to Alexandria on account of the great fame of Heraclas, who excelled especially in philosophic studies and other Greek learning, and whose appointment to the bishopric of the church there we have already mentioned.
3. There is extant also another epistle from the same Africanus to Aristides on the supposed discrepancy between Matthew and Luke in the Genealogies of Christ. In this he shows clearly the agreement of the evangelists, from an account which had come down to him, which we have already given in its proper place in the first book of this work.
