Composed and printed by THE UNIVERSITY OF CHICAGO PRESS, Chicago, Illinois, U.S.A. oi.uchicago.edu PREFACE Early in the course of my work on the text volume to Medinet Habu III: The Calendar, a project upon which Dr. Harold H. Nelson and I intend to collaborate, it became evident to me that I could not successfully grapple with the problems of Ramses III's temple calendar without a thorough investigation into all the calendarial phenomena of ancient Egypt. Once started, my own predilection for the subject led me farther and farther, so that what was originally intended as a page or two of footnotes has grown to the proportions of the present volume. Not all of what I shall present in these pages is new. My obligations to those chronological giants, Brugsch, Meyer, and Borchardt, are manifold; and I have ransacked the literature in order to avoid claiming as my own what had long ago been proposed. For some earlier propospls I have more proof to offer and may convince where others failed. Other propositions are mine and must stand on their own merits. Calendars and chronology are not of themselves difficult subjects, but they are frequently made so by the as- sumption of their devotees that everyone understands always what they are talking about. I intend to take the op- posite extreme and shall assume almost no special knowledge on the part of my readers. I shall not shrink from extended explanation or from repetition whenever understanding may be furthered. In the Introduction I shall pre- sent some of the basic astronomical and calendarial concepts with which we shall have to deal in later pages. Practiced chronologers may go on to the first chapter without concern, but I would urge all others to read the Introduction carefully. In the following pages I hope to demonstrate that the Egyptians had three calendars, two lunar and religious, one civil. I shall begin with a consideration of the lunar day and month, pass on to an analysis of the later lunar calendar, then discuss the probable nature of the early lunar calendar, and, finally, suggest a possible origin for the civil calendar. In three excursuses I shall offer solutions to various problems which arose naturally out of the calendarial material. The end product of our investigations will be, I hope, to persuade the reader to accept my present conviction that the lunar calendar is an essential key to a proper understanding of Egyptian festivals and thus in some meas- ure of Egyptian religion. In the preparation of these studies I have had the inestimable advantage of frequent discussion with my colleagues in the Oriental Institute. Professor Henri Frankfort permitted me to present my views for the criticism of his seminar. Professors John A. Wilson and Keith C. Seele and Dr. G. R. Hughes read the manuscript in preliminary form and made many valuable suggestions. Professors Otto Neugebauer of Brown University and William F. Al- bright of Johns Hopkins University gave penetrating criticism. My debts to Dr. Abd el-Mohsen Bakir of the Cairo Museum and to Professor G. Posener are acknowledged on the appropriate pages. Dr. T. George Allen has given me welcome editorial criticism. The drawings are the expert and painstaking work of Sue Richert. To all of them and to others not named I am deeply grateful. RICHARD A.
