IV.
THE foregoing Sketch of the history of this region shews that its architecture must belong to two entirely distinct epochs—the Roman period and the Mediæval period. It is proposed in the following description of the various edifices to treat of these two periods separately,—taking up first the buildings of the Roman period in regular sequence as they are met with in descending the Rhone from Lyons, and in the various localities along the Riviera, both west and east of Marseilles. Having thus exhausted the Roman monuments in the province, we shall return to Lyons, and repeat the journey southwards to Marseilles, and thence westwards and eastwards along the coast, taking note of the more important of the many remarkable Mediæval structures in which these localities abound.
This method will, we believe, be found to be much more satisfactory than any attempt to deal with the architecture in chronological order. That plan would be very confusing, the reader having under it to be constantly transferring himself from one region to another. By the system adopted he will at least always know where he is, and the situation of the buildings will thus be fixed in the mind. The disadvantage of this method admittedly is that structures of all the Mediæval periods are described together as they occur in each locality; but it is hoped that this disadvantage will be to some extent overcome by the introduction to the Mediæval period, in which the historic sequence and development of the architecture of the country in the Middle Ages is considered.
Following the above arrangement we shall now proceed with the description of the buildings, commencing with
