Among these newer efforts town-planning is one of the better known. Most of us now admit that if some scores of dwellings have to be run up for working-men or city-clerks--or even for University teachers in North Oxford--they can and should be planned with regard to the health and convenience and occupations of their probable tenants. Town-planning has taken rank as an art; it is sometimes styled a science and University professorships are named after it; in the London Conference of 1910 it got its _deductio in forum_ or at least its first dance. But it is still young and its possibilities undefined. Its name is apt to be applied to all sorts of building-schemes, and little attempt is made to assign it any specific sense. It is only slowly making its way towards the recognized method and the recognized principles which even an art requires. Here, it seemed, a student of ancient history might proffer parallels from antiquity, and especially from the Hellenistic and Roman ages, which somewhat resemble the present day in their care for the well-being of the individual. In enlarging the lecture I have tried not only to preserve this point of view, but also to treat the subject in a manner useful to classical scholars and historians. The details of Greek and Roman town-planning are probably little known to many who study Greek and Roman life, and though they have often been incidentally discussed,[1] they have never been collected. The material, however, is plentiful, and it illuminates vividly the character and meaning of that city-life which, in its different forms, was a vital element in both the Greek and the Roman world. Even our little towns of Silchester and Caerwent in Roman Britain become more intelligible by its aid. The Roman student gains perhaps more than the Hellenist from this inquiry, since the ancient Roman builder planned more regularly and the modern Roman archaeologist has dug more widely. But admirable German excavations at Priene, Miletus, and elsewhere declare that much may be learnt about Greek towns and in Greek lands. [1] For example, by Beloch in his volume on the cities of Campania, by Schulten in various essays, by Barthel in a recent inquiry into Roman Africa, and by others, to be cited below. Dr. J. Stübben in his _Städtebau_ (Darmstadt, ed. 2, 1907) and Mr. Raymond Unwin in his _Town planning in practice_ (London, 1909) have given interesting notices and illustrations of the subject for modern builders. The task of collecting and examining these details is not easy. It needs much local knowledge and many local books, all of which are hard to come by. Here, as in most branches of Roman history, we want a series of special inquiries into the fortunes of individual Roman towns in Italy and the provinces, carried out by men who combine two things which seldom go together, scientific and parochial knowledge. But a body of evidence already waits to be used, and though its discussion may lead--as it has led me--into topographical minutiae, where completeness and certainty are too often unattainable and errors are fatally easy, my results may nevertheless contain some new suggestions and may help some future workers. I have avoided technical terms as far as I could, and that not merely in the interests of the general reader. Such terms are too often both ugly and unnecessary. When a foreign scholar writes of a Roman town as 'scamnirt' or 'strigirt', it is hard to avoid the feeling that this is neither pleasant nor needful. Perhaps it is not even accurate, as I shall point...
