(iv) There remains, fourthly, evidence relating to early Rome itself, and to customs and observances which obtained there. These customs belong to the three fields of religion, agrarian land-settlement and war. All three exhibit the same principle, the division of a definite space by two straight lines crossing at right angles at its centre, and (if need be) the further division of such space by other lines parallel to the two main lines. The Roman augur who asked the will of Heaven marked off a square piece of sky or earth—his templum—into four quarters; in them he sought for his signs. The Roman general who encamped his troops, laid out their tents on a rectangular pattern governed by the same idea. The commissioners who assigned farming-plots on the public domains to emigrant citizens of Rome, planned these plots on the same rectangular scheme—as the map of rural Italy is witness to this day.
These Roman customs are very ancient. Later Romans deemed them as ancient as Rome itself, and, though such patriotic traditions belong rather to politics than to history, we find the actual customs well established when our knowledge first becomes full, about 200 B.C.[53] The Roman camp, for example, had reached its complex form long before the middle of the second century, when Polybius described it in words. Here, one can hardly doubt, are things older even than Rome. Scholars have talked, indeed, of a Greek origin or of an Etruscan origin, and the technical term for the Roman surveying instrument, groma, has been explained as the Greek word 'gnomon', borrowed through an Etruscan medium. But the name of a single instrument would not carry with it the origin of a whole art, even if this etymology were more certain than it actually is. Save for the riddle of Marzabotto (p. 61), we have no reason to connect the Etruscans with town-planning or with the Roman system of surveying. When the Roman antiquary Varro alleged that 'the Romans founded towns with Etruscan ritual', he set the fashion for many later assertions by Roman and modern writers.[54] But he did not prove his allegation, and it is not so clear as is generally assumed, that he meant 'Etruscan ritual' to include architectural town-planning as well as religious ceremonial.
These are Italian customs, far older than the beginnings of Greek influence on Rome, older than the systematic town-planning of the Greek lands, and older also than the Etruscans. They should be treated as an ancestral heritage of the Italian tribes kindred with Rome, and should be connected with the plan of Pompeii and with the far older Terremare. Many generations in the family tree have no doubt been lost. The genealogy can only be taken as conjectural. But it is a reasonable conjecture.
In their original character these customs were probably secular rather than religious. They took their rise as methods proved by primitive practice to be good methods for laying out land for farming or for encamping armies. But in early communities all customs that touched the State were quasi-religious; to ensure their due performance, they were carried out by religious officials. At Rome, therefore, more especially in early times, the augurs were concerned with the delimitation alike of farm-plots and of soldiers' tents. They testified that the settlement, whether rural or military, was duly made according to the ancestral customs sanctioned by the gods. After-ages secularized once more, and as they secularized, they also introduced science. It was, perhaps, Greek influence which brought in a stricter use of the rectangle and a greater care for regular planning.
It may be asked how all this applies to the planning of towns. We possess certainly no such clear evidence with respect to towns as with respect to divisions agrarian or military. But the town-plans which we shall meet in the following chapters show very much the same outlines as those of the camp or of the farm plots. They are based on the same essential element of two straight lines crossing at right angles in the centre of a (usually) square or oblong plot. This is an element which does not occur, at least in quite the same form, at Priene or in other Greek towns of which we know the plans, and it may well be called Italian. We need not hesitate to put town and camp side by side, and to accept the statement that the Roman camp was a city in arms. Nor need we hesitate to conjecture further that in the planning of the town, as in that of the camp, Greek influence may have added a more rigid use of rectangular 'insulae'. When that occurred, will be discussed in Chapter VI.
Whether the nomenclature of the augur, the soldier and the land-commissioner was adopted in the towns, is a more difficult, but fortunately a less important question. Modern writers speak of the cardo and the decumanus of Roman towns, and even apply to them more highly technical terms such as striga and scamnum. For the use of cardo in relation to towns there is some evidence (p. 107). But it is very slight, and for the use of the other terms there is next to no evidence at all.[55] The silence alike of literature and of inscriptions shows that they were, at the best, theoretical expressions, confined to the surveyor's office.[56]
CHAPTER VI
ITALIAN TOWN-PLANNING:
THE LATE REPUBLIC AND EARLY EMPIRE
During the later Republic and the earlier Empire many Italian towns were founded or re-founded. To this result several causes contributed. Like the Greeks before them, the Romans of the Republic sent out from time to time compact bodies of emigrants whenever the home population had grown too large for its narrow space. These bodies were each large enough to form a small town, and thus each migration meant—or might mean—the foundation of a new town full-grown from its birth. The Greeks generally established new and politically independent towns. The Romans followed another method. Their colonists remained subject to Rome and constituted new centres of Roman rule, small quasi-fortresses of Roman dominion in outlying lands. Often the military need for such a stronghold had more to do with the foundation of a 'colonia' than the presence of too many mouths in the city. Cicero, speaking of a 'colonia' planted at Narbo (now Narbonne) in southern Gaul about 118 B.C., and planted perhaps with some regard to an actual overflow of population in contemporary Rome, calls it nevertheless 'a colonia of Roman citizens, a watch-tower of the Roman people, a bulwark against the wild tribes of Gaul'. Those words state very clearly the main object of many such foundations under Republic and Empire alike.
Another reason for the establishment of 'coloniae' may be found in the history of the dying Republic and nascent Empire. During the civil wars of Sulla, of Caesar and of Octavian, huge armies were brought into the field by the rival military chiefs. As each conflict ended, huge masses of soldiery had to be discharged almost at once. For the sake of future peace it was imperative that these men should be quickly settled in some form of civic life in which they would abide. The form chosen was the familiar form of the 'colonia'. The time-expired soldiers were treated—not altogether unreasonably—as surplus population, and they were planted out in large bodies, sometimes in existing towns which needed population or at least a loyal population, sometimes in new towns established full-grown for the purpose. This method of dealing with discharged soldiers was continued during the early Empire, though it was then employed somewhat intermittently and the 'coloniae' were oftener planted in the provinces than in Italy itself; indeed the establishment of Italian 'coloniae', as distinct from grants of colonial rank by way of honour, almost ceased after A.D. 68.
It is not easy to determine the number of such new foundations of towns in Italy. Some seventy or eighty are recorded from the early and middle periods of the Republic—previous to about 120 B.C.; Sulla added a dozen or so; Octavian (Augustus) in his earlier years established or helped to establish about thirty.[57] But these figures can hardly represent the whole facts. The one certainty is that, through the causes just detailed, a very large number of the Italian towns were either founded full-grown or re-founded under new conditions during the later Roman Republic and the earlier Empire. Few towns in Italy developed as Rome herself developed, expanding from small beginnings in a slow continuous growth which was governed by convenience and opportunism and untouched by any new birth or systematic reconstruction.
Coincident with these processes of urban expansion, we find, in many towns which can be connected with the later Republic or the Empire, examples of a definite type of town-planning. This type has obvious analogies with earlier Italy and with the town-planning of the Greek world, but is also in certain respects distinct from either. The town areas with which we have now to deal are small squares or oblongs; they are divided by two main streets into four parts and by other and parallel streets into square or oblong house-blocks ('insulae'), and the rectangular scheme is carried through with some geometrical precision. The 'insulae', whatever their shape—square or oblong—are fairly uniform throughout. Only, those which line the north side of the E. and W. street are often larger than the rest (pp. 88, 125).[58] The two main streets appear to follow some method of orientation connected with augural science. As a rule, one of them runs north and south, the other east and west, and now and again the latter street seems to point to the spot where the sun rises above the horizon on the dawn of some day important in the history of the town.[59]
The public buildings of these towns are in general somewhat small and arranged with little attempt at processional or architectural splendour; they seldom dominate or even cross the scheme of streets. Open spaces are rare; the Forum, which corresponds to the Greek Agora, contains, like that, a paved open court, but this court is almost as much enclosed as the cloister of a mediaeval church or the quadrangle of a mediaeval college. Theatre and amphitheatre[60] might, no doubt, reach huge dimensions, but externally they were more often massive than ornamental and the amphitheatre often stood outside the city walls. Here and there a triumphal arch spanned a road where it approached a town, and provided the only architectural vista to be seen in most of these Roman towns.
Dimensions, of course, varied. There was no normal size for an infant town. Some, when first established, covered little more than 30 acres, the area of mediaeval Warwick. Others were four or five times as spacious; they were twice or nearly twice as large as mediaeval Oxford, no mean city in thirteenth-century England. Most of them, doubtless, grew beyond their first limits; a few spread as far as a square mile, twice the extent of mediaeval London. Similarly the 'insulae' varied from town to town. In one, Timgad, they were only 70 to 80 ft. square. Often they measured 75 to 80 yds. square, rather more than an acre, as at Florence, Turin, Pavia, Piacenza.[61] Occasionally they were larger, but they seldom exceeded three acres, and their average fell below the prevalent practice of modern chess-board planning.
In most towns, though not in all, the dimensions of the 'insulae' show a common element. In length or in breadth or in both, they usually approximate to 120 ft. or some multiple of that. The figure is significant. The unit of Roman land-surveying, the 'iugerum', was a rectangular space of 120 by 240 Roman feet—in English feet a tiny trifle less—and it seems to follow that 'insulae' were often laid out with definite reference to the 'iugerum'. The divisions may not have always been mathematically correct; our available plans are seldom good enough to let us judge of that,[62] and we do not know whether we ought to count the surface of the streets with the measurement of the 'insulae'. But the general practice seems clear, and it extended even to Britain (p. 129), and though blocks forming exactly a 'iugerum' or a half 'iugerum' are rare, the Italian land-measure certainly affected the civilization of the provincial towns.
In this system perhaps the most peculiar feature is the intermixture of square and oblong 'insulae'. It is not merely the variation which can be traced in Priene (fig. 5), where some blocks are rather more square or oblong than others, but where all approach the same norm. The Roman towns which we are now considering show two varieties of house-blocks. Sometimes the blocks are square; sometimes, perhaps more often, they are oblong approximating to a square, like the blocks of Priene. But in a few cases, as at Naples among the more ancient, and at Carthage among the later foundations, they are oblong and the oblongs are very long and narrow.
It is hard to detect any principle underlying the use of these various forms. No doubt differences of historical origin are ultimately the causes of the mixture. But our present knowledge does not reveal these origins. The evidence is, indeed, contradictory at every point. If the Graeco-Macedonian fashion be quoted as precedent for square or squarish 'insulae', the Terremare show the same. If the theoretical scheme of the earlier Roman camp seemed based on the long narrow oblong, the actual remains of legionary encampments of the second century B.C. at Numantia include many squares. If one part of Pompeii exhibits oblongs, another part is made up of squares. If Piacenza, first founded in north Italy about 183 B.C., and founded again a hundred and fifty years later, is laid out in squares, its coeval neighbour Modena prefers the oblong. If the old Greek city of Naples embodies an extreme type of oblong, so does the later Augustan Carthage (pp. 100, 113). In the historic period, it would seem, no sharp line was drawn, or felt to exist, between the various types of 'insulae'. In the main, the square or squarish-oblong was preferred. Local accidents, such as the convenience of the site at Carthage, led to occasional adoption of the narrower oblong.
The Roman land-surveyors, it is true, distinguished the square and the oblong in a very definite way. The square, they alleged, was proper to the Italian land or to such provincial soil as enjoyed the privilege of being taxed—or freed from taxation—on the Italian scale. The oblong they connected with the ordinary tax-paying soil of the provinces. This distinction, however, was not carried out even in the agrarian surveys with which these writers were especially concerned,[63] and it applies still less to the towns. No doubt it is a fiction of the office. It would be only human nature if the surveyors, finding both forms in use, should invent a theory to account for them.
The system sketched in the preceding paragraphs seems, as has been said (p. 73), to have sprung from a fusion of Greek or Graeco-Macedonian with Italian customs. Roman town-planning, like Roman art, was recast under Hellenistic influence and thus gained mathematical precision and symmetry. When this happened is doubtful. Foreign scholars often ascribe it to Augustus and find a special connexion between the first emperor and the chess-board town-plan. But the architect Vitruvius, who dedicated his book to Augustus and who gives some brief notice to town-planning, urges strongly that towns should not be laid out on the chess-board pattern, but rather on an eight-sided or (as we might call it) star-shaped plan.[64] He would hardly have denounced a scheme which had been specially taken up by his patron, nor indeed does his criticism of the chess-board system sound as if he were denouncing a novelty in Italian building.
On the other hand there seems no great difficulty in the idea that the regularization of the old Italian town-plan by Greek influence took place spontaneously in the late Republic. We cannot, indeed, date the change. It must remain doubtful whether it came by degrees or all at once,[65] and whether the right-angled plans of towns like Aquileia[66] or Piacenza belonged to their first foundation, i.e. to about 180 B.C., or to later rearrangements. But it seems reasonable to believe that a Graeco-Italian rectangular fashion of town-planning did supersede an earlier, irregular, Italian style, and had become supreme before the end of the Republic.
CHAPTER VII
INSTANCES OF ITALIAN TOWN-PLANS
The preceding chapters have dealt with the origins and general character of the Italian town-plan. We pass now to the remains which it has left in its own home, in Italy. These are many. In one city indeed, the greatest of all, no town-planning can be detected. Like Athens and Sparta, Rome shows that conservatism which marks so many capital cities. No part of it, so far as we know, was laid out on a rectangular or indeed on any plan.[67] It grew as it could. Its builders, above all its imperial builders, cared much for spectacular effects and architectural pomp. Even in late Republican times the gloomy mass of the Tabularium and the temples of the Capitol must have towered above the Forum in no mere accidental stateliness, and imperial Rome contained many buildings in many quarters to show that it was the capital of an Empire. But for town-planning we must go elsewhere.
The sources of our knowledge are twofold. In a few cases archaeological excavation has laid bare the paving of Roman streets or the foundation of Roman house-blocks. More often mediaeval and modern streets seem to follow ancient lines and the ancient town-plan, or a part of it, survives in use to-day. Such survivals are especially common in the north of Italy. It is not, indeed, possible to gather a full list of them. He who would do that needs a longer series of good town-maps and good local histories than exist at present; he needs, too, a wider knowledge of mediaeval Italian history and a closer personal acquaintance with modern Italian towns, than a classical scholar can attempt. But much can be learnt even from our limited material.[68]
The evidence of the streets needs, however, to be checked in every case. It would be rash to assume a Roman origin for an Italian town simply because its streets are old and their plan rectangular. There are many rectangular towns of mediaeval or modern origin. Such is Terra Nova, near the ancient Gela in Sicily, built by Frederick Stupor Mundi early in the thirteenth century. Such, too, Livorno, built by the Medici in the sixteenth century. Such, too, the many little military colonies of the Italian Republics, dotted over parts of northern and middle Italy. Often it is easy to prove that, despite their chess-board plans, these towns do not stand on Roman sites. Often the inquiry leads into regions remote from the study of ancient history.
Fortunately, enough examples can be identified as Roman to serve our purpose. Some of these occur in the Lombardy plain where, both under the Republic and at the outset of the Empire, many 'coloniae' were planted full-grown and where town-life on the Roman model was otherwise developed. Not all these towns survive to-day; not all of the survivors retain clear traces of their Roman town-plan; in nine cases, at least, the streets seem unmistakably to follow Roman lines. Four of the nine date from early days; in the late third and the early second centuries (218-183 B.C.), Piacenza, Bologna, Parma, and Modena, were built as new towns with the rank of 'colonia'. The first three of these were later refounded, about 40-20 B.C.—whether their streets were then laid out afresh is an open question—and Turin and Brescia were added. In addition, Verona, Pavia, and Como won municipal status in or before this later date, though when or how they came to be laid out symmetrically is not certain.[69] And there are other less certain examples.
Other instances, but not so many, may be quoted from south of the Apennines. At Florence, for example, and at Lucca 'coloniae' were planted full-grown and the street-plans still record the fact. At Naples, at Herculaneum, perhaps at Sorrento,[70] proofs survive of similar planning. But the towns of central Italy were in great part more ancient than the era of precise town-planning, and many of them were perched in true Italian fashion on lofty crags—praeruptis oppida saxis—which gave no room for square or oblong house-blocks. In the period of the dying Republic and nascent Empire fewer 'coloniae' were planted here than in the north, while in much of southern Italy towns have in all ages been comparatively rare.
In the towns just noted we can trace many, though not all, of the original house-blocks. Usually the blocks are square or nearly so, as at Turin, Verona, Pavia, Piacenza, Florence, Lucca. Less often they are long and even narrow rectangles, as at Modena, and Sorrento, and above all Naples, and as usual it is not easy to understand the reason for the difference (p. 80).
Turin (fig. 15).
Of all the examples of Roman town-planning known to us in Italy, Turin is by far the most famous.[71] Here the streets have survived almost intact, and excavations have confirmed the truth of the survival by revealing both the ancient road-metalling and the ancient town-walls and gates. Turin, Augusta Taurinorum, began about 28 B.C. as a 'colonia' planted by Augustus. Its walls enclosed an oblong of about 745 x 695 metres (127 acres).[72] The sides are represented (1) on the north by the Via Giulio, in the western part of which the southern edge of the street actually coincides with the line of the Roman town-wall, while further east the Porta Palatina enshrines an ancient gate; (2) on the west by the Via della Consolata, and the Via Siccardi, the east side of which latter street seems to stand upon the Roman town-wall; and (3) on the south by the Via della Cernaia and Via Teresa, the north side of which stands over the Roman southern town-wall. (4) The east wall agrees with no existing street but may be represented by a line drawn through the Carignano Theatre and the western front of the Palazzo Madama, which contains the actual towers of the Roman east gate.[73] The north-west corner, uncovered in 1884, is a sharp right angle. This feature recurs at Aosta and at Laibach (pp. 90, 116), both founded, like Turin, in the Augustan age, and seems to belong to that period; later, it gave place to the rounded angle visible at Timgad (p. 109) and in many Roman forts of the middle Empire.
Of the interior buildings of the town little is known. The Forum perhaps stood near the present Palazzo di Città, and the Theatre was traced in 1899 in the north-east corner of the town, occupying apparently, a complete insula;[74] of the private houses nothing definite seems to be recorded.
But the street-plan has survived intact, except in two outlying corners. The town was divided up into square or nearly square blocks, of which there were nine counting from east to west and eight from north to south. Most of these 'insulae' measured about 80 yds. square.[75] A few were larger, 80 x 120 yds.; these were ranged along the north side of the street now called Via Garibaldi (formerly Dora Grossa), which represents the Roman main street between the east and west gates—in the language of the Roman land-surveyors, the decumanus maximus. This street cut the town into two equal halves. The other divisions of the town were no less symmetrical. But, as there were nine 'insulae' from east to west, the main north and south street could not bisect the town. Indeed, the south gate seems to have had five house-blocks west of it and four east of it, while the Porta Palatina stands further west, with six blocks on the west side of it. The north and south gates, therefore, are not opposite.[76] Whether this was the original plan is not clear, nor is the age of the surviving walls and gates quite certain; the bonding courses in some of the masonry of the walls does not seem Augustan. But the street plan may unhesitatingly be assigned to the first establishment of the town, about 28 B.C. Since, it has been extended far beyond the Roman walls. Nearly all modern Turin has been laid out, bit by bit, in imitation and continuation of the original Roman lines.

Aosta (fig. 16).
Another example of an Italian town-plan, from the same date and district as Turin, is supplied by Augusta Praetoria, now Aosta, some fifty miles north of Turin in the Dora Baltea Valley, not far from the foot of Mont Blanc.[77] Aosta was founded by Augustus in 25 B.C. on a hitherto empty spot, to provide homes for time-expired soldiers and to serve as a quasi-fortress in an important Alpine valley. Its first inhabitants were 3,000 men discharged from the Praetorian Guard, with their wives and children; its population may have numbered at the outset some 15,000 free persons, besides slaves. The town, as it is known to us from excavation and observation, formed a rectangle 620 yds. long and 780 yds. wide, and covered an area of about 100 acres (fig. 16). The walls formed sharp right angles at the corners, as at Turin. Within the walls were an amphitheatre, a theatre, public baths, a structure covering nearly 2 acres and interpreted as a granary or (perhaps more correctly) as a cistern,[78] and private houses as yet unexplored. Beneath the chief streets were sewers, by which indeed these streets were mainly traced.
AOSTA
FIG. 16.
AOSTA
The whole was divided by a regular network of streets into rectangular blocks. According to the latest plan of the site, there were sixteen blocks, nearly identical in shape and averaging 145 x 180 yds. (5½ acres). That, however, is an incredible area for single house-blocks, and it is to be noted that Promis shows two further roads (A, A in fig. 16). If these are survivals of other such roads, Aosta may have contained thirty-two oblong 'insulae', each nearly 220 x 540 ft., or even sixty-four smaller and squarer 'insulae', measuring half that size.[79] Four gates gave entrance; those in the two longer sides which face north-west and south-east, are curiously far from the centre and indeed close to the south-western end of the town. It is, of course, impossible to determine, without spade-work, which of the recognizable buildings of Aosta date from the foundation of the place in 25 B.C. But the general internal scheme and the symmetrical and practically 'chess-board' pattern of streets must date from the first foundation.[80]
Florence (fig. 17).
A yet more interesting instance of a Roman town-plan preserved in many streets may be found in Florence.[81] In Roman times Florence was a 'colonia'. When this 'colonia' was planted is very doubtful. Perhaps the age of Sulla (90-80 B.C.) is the likeliest date; all that is actually certain is that the foundation was made before the end of the first century A.D. This 'colonia', like others, was laid out in chess-board fashion, and vestiges of its streets survive in the Centro which forms the heart of the present town. The Centro of Florence, as we see it to-day, is very modern. It was, indeed, laid out a generation ago by Italian architects who designed the broad streets crossing at right angles which form its characteristic. But this 'Haussmannization' revived, consciously or unconsciously, an old arrangement. The plan of Florence in 1427 shows a group of twenty unmistakable 'insulae', each of them about 1-1/8 acre in area, that is, very similar in size to the 'insulae' of Turin. This group is bounded by the modern streets Tornabuoni on the west, Porta Rossa on the south, Calzaioli on the east, Teatina on the north; it covers a rectangle of some 305 x 327 yds., not quite 21 acres.

FIG. 17B.
FLORENCE ABOUT 1795, FROM L. BARDI
The chief streets which seem to have preserved Roman lines are marked in black.
The original Roman town presumably extended beyond these narrow limits. But it is not easy to fix its area, nor are unmistakable 'insulae' to be detected outside them. On the west the Via Tornabuoni seems to have marked the Roman limit, as it does to-day. On the north, a probable line is given by the gateway, Por Episcopi, which once spanned the passage—now an open space—on the east side of the Archbishop's Palace (plan 17 B). That gateway stood between the Via Teatina and the next street to the north, the Via dei Cerretani, and the Roman north wall and ditch apparently ran along the intervals between these two modern streets—as indeed the lines of certain mediaeval lanes suggest. On the east the 'colonia' is supposed to have stretched to the Via del Proconsolo and the old Por S. Piero, probably the original east gate. Here the traces of 'insulae' are ill preserved; the space in question would contain, and the mediaeval streets would admit of, twelve blocks in addition to the twenty noted above.
The southern limit of Roman Florence towards the Arno is altogether doubtful. There are, or were, traces of Roman baths in the Via delle Terme, and it has been thought that the town stretched riverwards as far as the old gate Por S. Maria and the Piazza S. Trinità. The gate, however, is ill-placed and the line of wall implied by this theory is irregular. The mediaeval streets point rather to a south wall near the Via Porta Rossa. The baths might perhaps be due to a later Roman extension, such as we shall meet at Timgad (p. 113). The Por S. Maria may even be due to one of the reconstructions of Florence in the Middle Ages. At the end we must admit that without further evidence the limits of Roman Florence cannot be fixed for certain. But the limits indicated above give the not unsuitable dimensions of 46 acres (380 x 590 yds.), while the history of the twenty indubitable insulae of the Centro remains full of interest. We see here, as clearly as anywhere in the Roman world, how the regular Roman plan has gradually been distorted by encroachments and how, even in its irregularity, it has had power to drive modern builders towards its ancient fashion.
Of the interior of the Roman town little is known. The streets now called Strozzi and Speziali plainly preserve the Roman main street from east to west, while the Via Calimara overlies that which ran from north to south. Where these crossed was the mediaeval Mercato Vecchio, now enlarged into a patriotic Piazza Vittorio Emmanuele; here we may put the Roman forum, and here too, by the former church of S. Maria in Campidoglio, was the temple of Capitoline Juppiter. There were also theatres, a shrine of Isis, and, outside the Roman limit, an amphitheatre still discernible in the curves of certain streets (plan 17 B). However small Florentia was, it possessed the true elements of the Roman town.
Lucca (fig. 18).
A good parallel to Florence may be found at Lucca, the ancient Luca, where again the streets preserve a rectangular pattern without showing clearly what was its full extent. Luca is said to have been founded as a 'colonia' in 177 B.C., but the statement is of doubtful truth. Certainly it was a 'municipium' in Cicero's days, and a little later, in the period 40-20 B.C., it received the rank of 'colonia' and many colonists, taken (as an inscription says) from discharged soldiers of Legions VII and XXVI. Whether the surviving traces of town-planning date from this latter event or from some earlier age is not easy to say. But of the street-plan there can be no doubt, though its original size is uncertain. A rectangular area about 700 yds. from east to west and 360 yds. from north to south is divided into fifteen square or squarish 'insulae' arranged in three rows. Each insula is about 3 acres, but those of the middle row are larger than the rest (150 x 150 yds.). The Via S. Croce which runs along the south side of this row was perhaps the main east and west thoroughfare of the town, the 'decumanus maximus', so that the larger 'insulae' correspond to those which appear in the same position at Turin and elsewhere (p. 88).

Not Available
Whether there were other 'insulae' besides the fifteen is doubtful. On the east there were certainly none: the two narrow parallel streets at the east end of the area just described are obviously due to a growth of houses along the line of the original east wall. The other limits are more obscure. Probably the north and west walls stood a little outside of the Via Galli Tassi (once S. Pellegrino) and the Via S. Giorgio, but there may well have been a row of insulae, now obliterated, south of the Via del Battistero. One or two interior buildings are known. The Forum appears to have stood where is now the Piazza S. Michele in Foro; close by was a temple; in the north-eastern quarter, at the Piazza del Carmine, was probably the theatre; near it but outside the walls was the amphitheatre, its outlines still visible in the Piazza del Mercato (110 x 80 yds. in greatest dimensions).[82]
Herculaneum (fig. 19).
To these examples from north Italy may be added two from the south, Herculaneum and Naples. Herculaneum had much the same early history as its more important neighbour Pompeii. First an Oscan settlement, then Etruscan, then Samnite, it passed later under Roman rule. After the Social Wars (89 B.C.) it appears as a 'municipium'; of its history from that date till its destruction (A.D. 79) we know next to nothing. But excavations, commenced in the eighteenth century and now long suspended, have thrown light on its ground-plan.[83] This was a rectangular pattern of oblong house-blocks, measuring 54 x 89 yds., or in some cases a little more, and divided by streets varying from 15 to 30 ft. in width which ran at right angles or parallel to one another. Only a part of the town has been as yet unearthed. In that a broad colonnaded main street ran from north-west to south-east; on the north-east side of this street stood a row of house-blocks with a structure taken to be a Basilica, and on the south-west of it were ten house-blocks, one of which includes some public baths. At the north end of this area are a theatre and temple, at the south end two large structures which have been called temples but are more like large private houses; on the east (according to the eighteenth-century searchers) are graves.

HERCULANEUM
How much of the town has been uncovered, how much still lies hidden beneath the lava which overflowed it in A.D. 79, is disputed. Of its town-walls and gates no trace has yet been found. But nearly all its public buildings seem to be known; the graves on the east side, if correctly mapped by their discoverers and if coeval with the streets and houses, leave no room for further 'insulae' in that direction, while the great country-house called the 'Casa dei Papiri' plainly stood outside the town on the north-west. From these facts one modern writer has calculated that Herculaneum was less than a quarter of a mile long, less than 350 yds. broad, and less than 26 acres in extent—in short, not a sixth part of Pompeii. These measures are probably too small. The 'Basilica' on the north side of the main street cannot have stood on the extreme edge of the town. There must have been not three but four rows of house-blocks from south-west to north-east; the graves once noted in this quarter must be older than our Herculaneum or otherwise unconnected with it. The whole town must have been 40 or 45 rather than 25 acres in area. Even so it is a little town. The unenthusiastic references to it in ancient literature are, after all, truthful. Apart from the great villa outside it—possibly an imperial residence—it hardly deserved, or to-day deserves, to be excavated at the extraordinary cost which its excavation would involve.
The date of its planning is as doubtful as the extent of its area. One recent writer, Nissen, has suggested that it was reconstructed after an earthquake in A.D. 63 and was hardly completed before the eruption of 79. The earthquake is well attested. But it cannot possibly have wrecked the town so utterly as to cause wholesale rebuilding on new lines, and an inscription points rather to the time of Augustus. One Marcus Nonius Balbus (the text runs) built 'a basilica, gates and a wall at his own cost', and this builder Balbus was probably a contemporary of Augustus.[84] Others have preferred to think that the town-planning reveals Greek influences; they point to the Greek city of Naples, 7 miles west of Herculaneum, and the Doric temple at Pompeii, much the same distance east of it. However, neither the town-planning of Naples, to be discussed in the next paragraphs, nor that of Pompeii (p. 68), seems to be necessarily Greek, and Herculaneum itself contains nothing which cannot be explained as Italian. It is possible, though there is no record of the fact, that it received a settlement of discharged soldiers somewhere about 30 B.C. and was then laid out afresh. But here, as throughout this inquiry, more light is needed if the inquirer is to pass from guesswork to proven fact.
Naples (fig. 20).
One more example, from the neighbourhood of Herculaneum, may complete the list of Italian street-plans. Naples, the Greek and Roman Neapolis, was a Greek city, the most prosperous of the Greek towns in Campania.[85] After 90 B.C. it appears to have become a Roman 'municipium'. But it retained much of its Greek civilization. A writer of the early first century after Christ, Strabo, states that abundant traces of Greek life survived there, 'gymnasia, and athletic schools, and tribal divisions, and Greek names even for Roman things.' Even later Tacitus calls it a 'Greek city', and Greek was still used for official inscriptions there in the third century.

(TH = Theatre, T = Temple.)
This Neapolis town had, as certain existing streets declare, a peculiar form of town-planning. The area covered by these streets is an irregular space of 250 acres in the heart of the modern city, about 850 yds. from north to south and 1,000 yds. from east to west.[86] In Roman days three straight streets ran parallel from east to west and a large number of smaller streets, twenty or so, ran at right angles to them from north to south. The house-blocks enclosed by these streets were all of similar size and shape, a thin oblong of 35 x 180 metres (39 x 198 yds.). Some of the public buildings naturally trespassed on to more than one 'insula'; a theatre appears indeed to have stretched over parts of three. In general, the oblongs seem to have been laid out with great regularity and the angles are right angles, though the 'insulae' in the northern and southern rows of house-blocks cannot have been fully rectangular and symmetrical.
This town-plan of Naples differs from any of those noted above. Its blocks are narrower than those in any Italian town, unless in Modena, and while they resemble the 'insulae' of the sixth region of Pompeii (fig. 13), are far more regular than those. Almost the only close parallel is that of Roman Carthage (fig. 24). As Naples was by origin and character a Greek city, these narrow oblongs have been supposed to represent a Greek arrangement. They do not, however, correspond to anything that is known in the Greek lands, either of the Macedonian or of any earlier period. The conclusion is difficult to avoid that this Greek city of Naples adopted an Italian street-scheme, but laid it out with more scientific regularity than the early Italians themselves. When this occurred and why, is wholly unknown. That the result is not an unpractical form of building is shown by the fact that similar long and narrow house-blocks are a characteristic feature of modern Liverpool, though they seldom occur in other English towns, unless intermixed with square and other blocks.
CHAPTER VIII
ROMAN PROVINCIAL TOWN-PLANS. I
The provinces, and above all the western provinces of the Roman Empire, tell us even more than Italy about Roman town-planning. But they tell it in another way. They contain many towns which were founded full-grown, or re-founded and at the same time rebuilt, and which were in either case laid out on the Roman plan. But the modern successors of these towns have rarely kept the network of their ancient streets in recognizable detail. Though walls, gates, temples, baths, palaces, amphitheatres still stand stubbornly erect amidst a flood of modern dwellings, they are but the islands which mark a submerged area. The paths and passages by which men once moved across that area have vanished beneath the waves and cannot be recovered from any survey of these visible fragments. There is hardly one modern town in all the European and African provinces of the Roman Empire which still uses any considerable part of its ancient street-plan. In our own country there is no single case. In Gaul and Germany, two or three streets in Cologne and one or two in Trier are the sole survivals.[87] In Illyricum there is no example unless possibly at Belgrade. In the Spanish peninsula the town of Braga in northern Portugal seems to stand alone. In Roman Africa—Tunis, Algiers and Morocco—no instance has survived the Arab conquest.[88]
If, however, survivals of ancient streets are as rare in the provinces as they are common in Italy, the provinces yield other evidence unknown to Italy. In these lands, and above all in Africa, the sites of many Roman towns have lain desolate and untouched since Roman days, waiting for the excavator to recover the unspoilt pattern of their streets. If the Roman Empire brought to certain provinces, as it unquestionably did to Africa, the happiest period in their history till almost the present day, that only makes their remains the more noteworthy and instructive. Here the new art of excavation has already achieved many and varied successes. In the western Empire one town, Silchester in Britain, has been wholly uncovered within the circuit of its walls. Others, like Caerwent in Britain or Timgad and Carthage in Africa, have been methodically examined, though the inquiries have not yet touched or perhaps can never touch their whole areas. In others again, some of which lie in the east, occasional search or even chance discoveries have shed welcome light. Our knowledge is more than enough already for the purposes of this chapter.
We can already see that the town-plan described in the foregoing pages was widely used in the provinces of the Empire. We find it in Africa, in Central and Western Europe, and indeed wherever Rorrran remains have been carefully excavated; we find it even in remote Britain amidst conditions which make its use seem premature. Where excavation has as yet yielded no proofs, other evidence fills the gap. In southern Gaul, as it happens, archaeological remains are unhelpful. But just there an inscription has come to light, the only one of its kind in the Roman world, which proves that one at least of the 'coloniae' of Gallia Narbonensis was laid out in rectangular oblong plots. It is clear enough that this town-plan was one of the forms through which the Italian civilization diffused itself over the western provinces.
The exact measure of its popularity is, however, hard to determine. In the east it found little entrance. There, the very similar Macedonian and Greek methods of town-planning were rooted firmly, long before Rome conquered Greece or Asia Minor or Syria or Egypt. The few town-plans which have been noted in these lands, and which may be assigned more or less conjecturally to the Roman era, seem to be Hellenic or Hellenistic rather than Italian. They show broad stately streets, colonnades, vistas, which belong to the east and not to Italy. Even in the west, the rule of the chess-board was sometimes broken. Aquincum, near Budapest, became a 'municipium' under Hadrian; its ruins, so far as hitherto planned, exhibit no true street-planning. But that may be due to its history, for it seems not to have been founded full-grown, but to have slowly developed as best it could, and to have won municipal status at the end.
Roman Africa is here, as so often, our best source of knowledge. At Timgad (p. 109), a town laid out in Roman fashion with a rigid 'chess-board' of streets was subsequently enlarged on irregular and almost chaotic lines. At Gigthi, in the south-east of Tunis, the streets around the Forum, itself rectangular enough, do not run parallel or at right angles to it or to one another.[89] At Thibilis, on the border of Tunis and Algeria, the streets, so far as they have yet been uncovered, diverge widely from the chess-board pattern.[90] One French archaeologist has even declared that most of the towns in Roman Africa lacked this pattern.[91] Our evidence is perhaps still too slight to prove or disprove that conclusion. Few African towns have been sufficiently uncovered to show the street-plan.[92] But town-life was well developed in Roman Africa. It is hardly credible that the Africans learnt all the rest of Roman city civilization and city government, and left out the planning. The individual cases of such planning which will be quoted in the following pages tell their own tale—that, while the strict rule was often broken, it was the rule.
Orange (fig. 21).
The case which deserves the first place stands by itself. It is the one piece of written evidence (as distinct from structural remains) which has survived from Roman town-planning. Curiously enough, it was found not in Italy but in a province, and a province which, for all its wealth of Roman buildings, has not yet revealed the smallest structural proof of Roman town-planning. In April 1904 a scrap of inscribed marble, little more than 18 in. broad and high, was dug up at Orange, in southern France, right in the centre of the town. It is a waif from a lengthy document. But it chances to be intelligible. It enumerates six plots of land—'merides' it calls them, from a Greek word meaning 'share' or 'division'—which seem to have formed one parcel: each plot is numbered, and the length of its frontage on the public way (in fronte), the name of its lessee or manceps and that of his surety (fideiussor) are added. The frontages of four plots make up 200 ft. (those of the other two are lost), and it has been suggested that the six together made up 240 ft. The depth—which is not stated on the surviving fragment, but was doubtless uniform for all the plots—may then have been 120 ft., and the whole parcel may have covered 120 x 240 ft., that is, a Roman 'iugerum'. It was plainly a piece of town property. The largest 'meris', Plot v, measured only 25 by 40 yds. and no one would care for such a field or farm. Besides, this plot at one end adjoined a 'ludus' or gladiatorial school, and it fronted AD K, ad kardinem, on to the street called in surveying language the 'cardo'. The whole land apparently belonged to one lessee who held it from the municipality on something like a perpetual lease.[93]
