Chapter 10

These points yielded a regular plan of streets crossing at right angles, which in many of its features much resembles that of Autun. Thirteen streets were traced running east and west, and eight (Dr. Graven says seven but his plan shows eight) running north and south. The east and west streets, with two exceptions, lay some 320 ft. from one another. The north and south streets varied, some observing that distance, others being no more than 260 ft. apart. As a result, the rectangular house-blocks varied also in size. The largest seem to be those which fronted a street that crossed the town from east to west, from the Imperial Palace to the Baths and the West Gate, and corresponds roughly with the present Kaiserstrasse. This may well have been the _decumanus_, the main east and west street of the 'colonia', and hence the house-blocks fronting it may have been unusually large (p. 77). One of them, near the Neumarkt, reached the awkward size of nearly 3-1/2 acres (320 x 460 ft.). Others elsewhere were smaller, many measuring 320 x 320 ft., and others again 320 x 245 ft., rather less than 2 acres. In general, the 'insulae' on the east and west sides of the town were larger than those in the centre. The whole has a resemblance to Autun, and is more irregular than writers on Trier are ready to allow.[107]

[107] Gräven estimated that, except in the central street, all the 'insulae' measured 300 Roman ft. (290 English ft., 88 metres), but his plan suggests rather 100 metres. We need in reality that larger plan which he did not live to complete.

How many houses may have occupied either a large or a small 'insula' is uncertain; indeed, we know next to nothing of the private houses of Roman Trier. Nor can we fix the number of the 'insulae'. On the west, and still more on the east and south-east of the town, much of the area was not touched by the drainage works and therefore went unexplored. We have proof only of streets and buildings for a mile in length and half a mile in breadth.

Nevertheless we may make some guess at the original area. The streetage itself plainly dates from the original foundation of the Romano-Gaulish town by Augustus. There is, indeed, no other epoch in its history, so far as we know it, when a complete laying out could have been carried through. On the other hand, it is not probable that the first town was a mile long and half a mile wide. Possibly, as an acute German archaeologist has suggested, the small 'insulae' in the south of the town may indicate the line of an original wall and ditch which, like the first walls of Timgad, were overrun later by an expanding town. Certainly, early graves found hereabouts show that this space lay once outside the inhabited area, and similar evidence has been noted both on the north of the town in the Simeonstrasse, and on the west near the Mosel Bridge. If this be so, Augusta Treverorum may have at first covered only 120 or 130 acres; then, as the place spread beyond its original limits, its builders followed more or less closely the lines of the first streets, and, save near the Porta Nigra, continued the chess-board pattern as it was continued at Turin.

_Silchester_ (figs. 31, 32).

Silchester, Calleva Atrebatum (fig. 31), shows a different picture, which is the more interesting because the excavations carried out in 1890-1909 have given us a fuller knowledge of the town than of any other Roman site in the western provinces.[108] It was, apparently, the old tribal capital of the Atrebates and the county-town of its district in Roman days; though not possessing the full municipal status, it was probably the seat of local government for a considerable neighbourhood. In outline it was an irregular eight-sided area of 100 acres, defended by a strong stone wall, which was added long after the original foundation. Internally it was divided up by streets which, except near the east gate, run parallel or at right angles to one another. Its buildings are: a Forum and Basilica, a suite of public baths, four small temples, a small Christian church, a hotel, and a large number of private houses. Its area is by no means filled with buildings. Garden ground must have been common and cheap, and the buildings themselves do not form continuous streets; they do not even front the roadway in the manner of houses in Italian towns. In these respects Silchester differs widely from any of the examples which we have already considered, so far as their internal buildings are known to us. I will not call it a 'garden city', for a garden city represents an attempt to add some of the features of the country to a town. Silchester, I fancy, represents the exact opposite. It is an attempt to insert urban features into a country-side.

[108] For accounts of the Silchester excavations, see _Archaeologia_, vols. lii-lxii, and _Victoria Hist. of Hampshire_, i. 271, 350; large plan by W.H. St. John Hope (1:1,800) in _Archaeol._ lxi.

Most of it must have been laid out at once. At any rate, the area of which the 'insulae' numbered X, XXI, XXXV, and XIX form the corners, and the Forum the centre, must have been planned complete from the first. This covers just 40 acres, and is divided into rectangular plots of which the smallest covers a little less than an acre and a half, while the largest fall little short of 3-1/2 acres.[109] Outside this area, the division of the town into 'insulae' is less completely carried through, although most of the streets run straight on as far as the walls, and one or two details may tempt us to think that the division into 'insulae' was at some time extended beyond the line ultimately taken by the walls.

[109] The plots are of three sizes, two being 3-4 acres (128 x 130 yds.), six about 2.4 acres (128 x 89 yds.), and six about 1.4 acres (89 x 80 yds.). In the third size the dimension of 240 Roman feet (p. 79) can perhaps be recognized.

But whatever the exact amount of Roman building and Roman street-plan given to Silchester when it was first laid out, the place is not in effect a real town. It is not merely that, as I have said, the houses do not form continuous streets. A glance at the houses will show that they could not possibly be fitted into streets. The types of house here visible are not town houses. They are the types which appear among the 'villas', that is, the landlords' or the farmers' dwellings, up and down the rural districts of Roman Britain and northern Gaul, and the town which they constitute is a conglomeration of country houses. The reverse has taken place of that which we often see to-day in England. Our modern builders and architects had--until perhaps quite recently--only one idea of a small house, the house, namely, which to-day characterizes the monotonous streets in the poorer quarters of our new towns, with its front door and bow window on one side, its offices behind, and its two other sides left blank for other houses to stand against. This is a town house. Yet our modern builders use it, all by itself, in the most desolate country districts. I came across one such not long ago, when driving over a lonely valley in Exmoor. There it stood, with no other house near it, yet with its two sides blankly waiting for the street that ought to form itself to the right and left.

The opposite of this has occurred at Calleva; here the rural house has been used, with scarcely a change, to form a town. We see the Roman street-plan introduced in surroundings which are not properly urban. The outward expression of the civilised municipal system jostles against a provincial and rural life. Here was a premature attempt to municipalize the Briton, which outstripped the readiness of the Briton to be municipalized. Silchester was probably a tribal centre before the Roman came; for awhile it may have remained much the same under Roman rule. But forty years after the Roman Conquest, in the reign of Vespasian (about A.D. 70-85), the Romanization of the whole province appears to have rapidly advanced. It was, indeed, encouraged by the Home Government. Various details suggest that the laying out of Silchester belonged to this very date. But to this the Callevan failed to rise. He learnt much from Rome; he learnt even town-life; he did not learn town-life in its highest form. When his town had been 'haussmannized' and fitted with Roman streets, and equipped with Roman Forum and Basilica, and the rest, he yet continued to live--perhaps more happily than the true townsman--in his irregularly grouped houses and cottages amid an expanse of gardens. The area of Silchester differed little from that of Aosta; its population, if we may judge by the number of dwelling-houses, was hardly as large as that of Timgad.

_Caerwent_ (fig. 33).

I turn lastly to another Romano-British town, Caerwent (Venta Silurum), between Chepstow and Newport in Monmouthshire. It is a smaller town than Silchester. Both towns perhaps began with the same area, 40 or 45 acres. But Caerwent never expanded; it remained not much more than 45 acres within the walls. Land was probably valuable within it; certainly its houses are packed closer, and its garden ground is smaller than at Silchester. Its general type is, however, the same. It has a very similar Forum and Basilica, Temples, an Amphitheatre, and a large number of private houses which resemble closely those of Silchester. It has, moreover, at least in the parts that have been so far excavated, distinct traces of a rectangular street pattern, which, if it was carried through the whole town, would provide (including the Forum) twenty 'insulae'. The size of these blocks cannot be determined with any precision. Indeed, in some cases the houses seem to have encroached on and distorted the street-plan. Probably it would be true to say that the average block covered an acre and a half or an acre and two-thirds.[110] We do not know enough of the history of Caerwent to do more than guess how this street-plan came to it. Very likely the same process of establishing a Roman-looking town for a local capital was adopted here as at Silchester. Very likely the step was taken in the same period as at Silchester, that is, in the last thirty years of the first century. Its occurrence is significant. Caerwent lay remote in the far west, with nothing but garrisons beyond it. It was the outpost of Roman city life towards the Atlantic. It was the only town of Roman municipal plan in Britain which was swept by Atlantic breezes.[111]

[110] The three best defined examples measure about 260 x 260, 260 x 280, 275 x 275 ft. (1.55, 1.61, and 1.73 acres respectively). The unit of 240 Roman feet (p. 79) does not appear at Caerwent.

[111] Accounts of the Caerwent Excavations, 1899-1910, will be found in _Archaeologia_, vols. lvii-lxii. A good plan of the whole town, from which fig. 33 is taken, was issued in vol. lxii, plate 64, by Mr. F. King, architect to the excavations (scale, 1:900).

Silchester and Caerwent did not stand alone in Britain. At Wroxeter, the ancient Viroconium, tribal centre of the Cornovii and a Romano-British country-town much like Silchester, though somewhat larger, oblong 'insulae' have recently been detected by Mr. J.P. Bushe-Fox which measure 103 x 126 yds. (2-2/3 acres). At Cirencester, the Romano-British centre for the canton of the Dobuni and a still larger town than Wroxeter, the 'insulae' near the Basilica seem to have measured as much as 120 yards in length, though full details have not yet been obtained. Both these towns may be ascribed to the later years of the first century and to the same civilizing process as Silchester and Caerwent. As further Romano-British towns are uncovered, we may therefore hope for more examples. However imperfectly the inner meaning of town-planning was understood, it was plainly common in the south of Roman Britain.

NOTE. THE EASTERN PROVINCES.

To complete the survey of Roman provincial town-planning, we must glance briefly at the East. Here towns of Roman origin were few, and of those few scarcely any are well known. But they do not lack interest. For example, take Antinoê, built by Hadrian in memory of his favourite Antinous, on the banks of the Nile. It was a parallelogram more than 3 miles round, which covered an area of 360 acres. Two main streets, each colonnaded, crossed at right angles and cut it into four parts. Of the other streets, nothing certain seems to be known. But references to the town in papyri denote four quarters of it by various letters, Alpha, Beta, Gamma, Delta, and distinguish its house-blocks by the term Plintheion with a numeral attached. Thus, a house is described as lying 'in the letter Delta and the Plintheion 7'. Our documents show that there were in Antinoê at least eleven of these Plintheia.[112] It is fairly plain that they are rectangular 'insulae', of either Roman or Hellenic type, while the general fashion of the town and of its monuments suggest a Greek rather than an Italian city.

[112] _Exploration des ruines d' Antinoe_, by A.C. Gayet (Annales du Musée Guimet, xxvi, Paris, 1897); _Grundzüge der Papyruskunde,_ Wilcken, i, pp. 49, 50. Professor A.S. Hunt refers me to the following papyri:--Reinach, 49. 11; Oxyrhynchus, 1110. 9-10 and note there; Brit. Mus. 1164 (c) 12. The numeration of the divisions of the town by letters was borrowed from Alexandria, where the five parts of the city were known as A, B, C, D, E. For plans see the Napoleonic _Description d'Égypte_ iv (Paris, 1817), plate 53, and E. Jomard, _Antiquités d'Égypte_ (1818), chap. xv.

Another instance may be found still further east, in the land beyond Jordan, at the capital of the Haurân, Bosrâ, anciently Bostra. Little has been achieved in the way of exploration of this site beyond studies of the stately ruins of theatres, palaces, temples, triumphal arches, aqueducts. Little can therefore be said as to the date of its ground-plan. But it was rectangular in outline, or nearly so; and its streets crossed at right angles and enclosed rectangular insulae.[113] The place owes all its greatness to Rome. During the second century it was the fortress of the Legio III Cyrenaica, which guarded this part of the eastern Roman frontier. About A.D. 225 it became a 'colonia,' and perhaps we should date from this the town-plan just described (fig. 34).

[113] Baedeker, _Palestine and Syria_ (1906), p. 162.

This rectangular planning remained long in use in the Eastern Empire. When in A.D. 705 (as it seems) the town of Chersonnesus in the Crimea was rebuilt after a total destruction, it was rebuilt on a symmetrical plan of oblong 'insulae' (25-30 by 60-70 yds. area). Its streets were mean and narrow. But their plan at least was apparently more regular than that of their predecessors.[114]
