In the following pages the attempt is made to indicate the principles on which the topography of Asia Minor must be studied, and to give a sketch of the subject as a whole. In addition to this I give a number of details about special points which have been collected in the course of my readings, and which have become too numerous to hold together in my mind, amid the distractions of other work, without the printer's aid. I have not tried to make them complete, or to give what may be found in ordinary sources of information. Every fact has been gathered from the original sources, and represents the impression which the context has made on my mind : I cannot, of course, feel sure that the impression has always been correct, but from the first page to the last this sketch springs from a fresh collection and an independent valuation of the material.

A comparison of the lists of cities in each province whose exisience at various periods can be traced forms the basis of this study, and a brief criticism of the chief authorities is necessary as an introduction.

First may be mentioned the Notitisæ Episcopatuum. The most important Notitiae published by Parthey and Pinder are VII., VIII., IX., I., III., X., XIII. All the unpublished Notitiæ that I have seen are mere variations of some of these.
