I will first endeavour, in accordance with my original plan, to give an account of the war between Antiochus and Ptolemy for the possession of Coele-Syria. Though I am fully aware that at the period, at which I have stopped in my Greek history, this war was all but decided and concluded, I have yet deliberately chosen this particular break and division in my narrative; believing that I shall effectually provide against the possibility of mistakes on the part of my readers in regard to dates, if I indicate in the course of my narrative the years in this Olympiad in which the events in the several parts of the world, as well as in Greece, began and ended. For I think nothing more essential to the clearness of my history of this Olympiad than to avoid confusing the several narratives. Our object should be to distinguish and keep them separate as much as possible, until we come to the next Olympiad, and begin setting down the contemporary events in the several countries under each year. For since I have undertaken to write, not a particular, but a universal history, and have ventured upon a plan on a greater scale, as I have already shown, than any of my predecessors, it will be necessary also for me to take greater care than they, as to my method of treatment and arrangement; so as to secure clearness, both in the details, and in the general view adopted in my history. I will accordingly go back a short way in the history of the kingdoms of Antiochus and Ptolemy, and try to fix upon a starting-point for my narrative which shall be accepted and recognised by all: for this is a matter of the first importance.
