Secondly, while I have been at work on the lectures, the idea seems to have been slowly gaining ground that the patrician religion of the early City-state, which became so highly formalised, so clean and austere, and eventually so political, was really the religion of an invading race, like that of the Achaeans in Greece, engrafted on the religion of a primitive and less civilised population. I have not definitely adopted this idea; but I am inclined to think that a good deal of what I have said in the earlier lectures may be found to support it. Once only, in Lecture XVII., I have used it myself to support a hypothesis there advanced. I have retained the familiar English spelling of certain divine names, _e.g._ Jupiter (instead of Iuppiter), as less startling to British readers. I wish to express my very deep obligations to the works of Prof. Wissowa and Dr. J. G. Frazer, and also to Mr. R. R. Marett, who gave me useful personal help in my second and third lectures. From Prof. Wissowa and Dr. Frazer I have had the misfortune to differ on one or two points; but "difference of opinion is the salt of life," as a great scholar said to me not long ago. In reading the proofs I have had much kind and valuable help from my Oxford friends Mr. Cyril Bailey and Mr. A. S. L. Farquharson, who have read certain parts of the work, and to whose suggestions I am greatly indebted. The whole has been read through by my old pupil Mr. Hugh Parr, now of Clifton College, to whom my best thanks are due for his timely discovery of many misprints and awkward expressions. The loyalty and goodwill of my old Oxford pupils never seem to fail me. W. W. F. Kingham, Oxon, _3rd March 1911_. CONTENTS LECTURE I INTRODUCTORY PAGE Accounts of the Roman religion in recent standard works; a hard and highly formalised system. Its interest lies partly in this fact. How did it come to be so?

A useful definition applied to the plan of Lectures I.-X.; including (1) survivals of primitive or quasi-magical religion; (2) the religion of the agricultural family; (3) that of the City-state, in its simplest form, and in its first period of expansion.
