Of the chief writings of Julius Africanus (called Sextus Africanus by Suidas), who wrote at Emmaus and Alexandria c. 220, only fragments remain.  A Letter to Origen is complete.  His principal work was a Chronicon from the Creation to a.d. 221, in Five Books.  Of this Dr. Salmon (D.C.B. i. 56) thinks the doxology quoted by Basil was the conclusion.
