In offering to the public two more volumes on the state-religion of the Greek world, I must express my regrets that the interval between their appearance and that of the first two has been so long. I may plead for indulgence on the grounds that multifarious official duties have borne heavily upon me, and that I have devoted what leisure I have had to preparing myself for the completion of my task. I have gained this at least from the long delay, that I have been able to profit by the many works and monographs of Continental and English scholars relating directly or indirectly to the subject, to reconsider many questions and to form more mature opinions on many important points. The results of the researches and discoveries throughout the last decade bearing on the history of religion have given us the opportunity, if we choose to avail ourselves of it, of improving the anthropological method in its application to the problems of comparative religion; and the great discoveries in Crete have thrown new light on certain questions that arise in the study of the classical polytheism. Every year also enriches the record with new material, from newly discovered inscriptions and other monuments.
