(c.160-c.240) Chronographer, east Africa. He is thought to have been of Roman descent; he studied at Alexandria and restored the city of Emmaus in Palestine and called it Nikopolis. His "Chronicle," in five books, covered the time from the Creation to A.D. 221, and was the first Christian attempt at universal history and the source of later Christian chronography; his "Embroideries," or "Puzzles," is a kind of encyclopedia of sciences, much esteemed by the Greek Fathers. A letter to Origen, disputing the authenticity of the story of Susanna, is his only complete work extant; another letter of which only fragments exist deals with the genealogy of Christ.
