<head>I. From the Preface</head>These are the principal events included in the above-mentioned Olympiad, that is in the space of four years which we term an Olympiad, and I shall attempt to narrate them in two Books.
I am not unaware that my work owing to the uniformity of its composition has a certain severity, and will suit the taste and gain the approval of only one class of reader.
For nearly all other writers, or at least most of them, by dealing with every branch of history, attract many kinds of people to the perusal of their works.
The genealogical side appeals to those who are fond of a story, and the account of colonies, the foundation of cities, and their ties of kindred, such as we find, for instance, in Ephorus, attracts the curious and lovers of recondite longer,
while the student of politics is interested in the doings of nations, cities, and monarchs. As I have confined my attention strictly to these last matters and as my whole work treats of nothing else, it is, as I say, adapted only to one sort of reader, and its perusal will have no attractions for the larger number.
I have stated elsewhere at some length my reason for choosing to exclude other branches of history and chronicle actions alone, but there is no harm in briefly reminding my readers of it here in order to impress it on them.
