The Extant Fragments of the Five Books of the Chronography of Julius Africanus

And Africanus, in the third book of his History, writes: Now the first Olympiad recorded—which, however, was really the fourteenth—was the period when Corœbus was victor;¹¹¹³ at that time Ahaz was in the first year of his reign in Jerusalem. Then in the fourth book he says: It is therefore with the first year of the reign of Ahaz that we have shown the first Olympiad to fall in.
