The influence of another twentieth-century classic, M. I. Rostovt- zeff's
Something must be said about the apparent omissions and idiosyncrasies. We have not thought it necessary to write an account of the sources for the period. The major literary sources (Tacitus, Suetonius, Cassius Dio, Josephus) have been very well served by recent scholarship and this period is not, from the point of view of the literary evidence, as problematical as those which follow. The range of documentary, archaeological and numismatic evidence for different topics and regions has been thought best left to individual contributors to summarize as they considered appropriate.
The presence in this volume of a chapter on the unification of Italy might be thought an oddity. Its inclusion here was a decision taken in consultation with the editors of the new edition of Volume ix, on the ground that the Augustan period is a good standpoint from which to consider a process which cannot really be considered complete before that, and perhaps not fully complete even by the Augustan age. Two of the chapters (those on Egypt and on the development of Roman law) will have counterparts in Volume xii (a.d. 193-337), but not in Volume xi; in both cases the accounts given here are intended to be generally valid for the first two centuries a.d. The treatment of Judaea and of the origins of Christianity posed difficulties of organization and articulation, given the extensive overlap of subject-matter. We nevertheless decided to invite different scholars to write these sections and to juxtapose them. It still seems surprising that the first edition of this volume contains no account of the origins and early growth of Christianity, a phenomenon which is, from the point of view of the subsequent development of civilization, surely the most important single feature of our period. Some degree of overlap with other standard works of reference is inevitable. We have, however, deliberately tried to avoid this in the case of literature by including a chapter which is intended as a history of literary activity in its social context, rather than a history of the literature of the period as such, which can be found in
