Sextus Julius Africanus, a Christian writer of the 3d century. Though of African birth or descent, he lived in the city of Emmaus, Palestine, of which, in a mission to Borne about 220, he procured the rebuilding after it had been burned. The new city was called Nicopolis. He is said to have been afterward a bishop. He composed a Chronicon in five books, commencing with the creation and closing with the year 221 of the present era, fragments of which have been preserved by Eusebius, Syncellus, and others. Two letters by him are also extant.
