The system of references adopted perhaps calls for some explanation. As I have no right to expect my readers to take what I say for gospel, I should have preferred to give my authority for every statement made by me in the text. But there are often many authorities supporting the same statement, and some discrimination between them was necessary unless these two volumes were to be swollen to an intolerable length. The same consideration for brevity, too, has often led me to quote at second or third hand rather than at first. References to well-known passages in the more widely read classical writers and Christian Fathers are not needed by scholarly readers, while to others they are difficult to check or verify. I have therefore deliberately and of choice preferred the less recondite sources to the more recondite, and have never hesitated to refer the reader to encyclopaedias, popular lectures, and the works avowedly addressed to the general public of writers like Renan and Mahaffy, rather than to the sources from which they have themselves drawn their information. In so doing, however, I have never consciously failed to check the statement quoted with the original source, and to see, so far as in me lay, that it correctly represents its purport. A fairly long experience has convinced me that to many readers the “Apoll. Rhod. ac Nigid. Schuster, p. 41” and the “Clemens de div. serv. Su 20” dear to certain German professors and their English admirers mean very little, and to the greater public nothing at all. For the translations which appear in the text or notes I have gleaned from all sources, but, except where expressly mentioned, I must personally accept all responsibility for them, and in cases in which any doubt seemed possible I have generally added the words of the original document. Finally, I have not attempted to impress my own opinion on my readers, but merely to give them the material on which they can form their own; and where I have found myself in doubt as to what the facts of the case really were, I have never scrupled to say so. This is not a counsel of perfection, but the one which on the whole seemed to me best. If by doing so I have succeeded in sending to the documents themselves a few readers hitherto ignorant of them, I shall think I have not wasted my time. F. LEGGE. 6 GRAY’S INN SQUARE, _July 1914_. P.S. The outbreak of the war has caused the publication of this book to be postponed. I regret the delay the less that it has enabled me to make use of several works and studies which have appeared during the last twelve months. F. L.
