FIG. 2.
PLAN OF PIRAEUS

Thurii.

Another town ascribed to Hippodamus is the colony which the Athenians and others planted in 443 B.C. at Thurii in southern Italy, of which Herodotus himself is said to have been one of the original colonists. Its site has never been excavated, and indeed one might doubt whether excavation would show the street plan of 443 B.C. or that of a later and possibly even of a Roman age, when the town was recolonized on the Roman system. But the historian Diodorus, writing in the first century B.C. and no doubt embodying much older matter, records a pertinent detail. The town, he says, was divided lengthways by four streets and crossways by three. Plainly, therefore, it had a definite and rectangular street-planning, though the brevity of the historian does not enable us to decide how many house-blocks it had and how far the lesser streets were symmetrical with these seven principal thoroughfares. In most of the cases which we shall meet in the following sections of this treatise, the number of streets running-straight or at right angles is very much greater than the number assigned to Thurii. I may refer for example to the plans of Priene, Miletus, and Timgad.

Rhodes.

A third city assigned to Hippodamus is Rhodes. This, according to Strabo, was laid out by 'the architect of the Piraeus'; according to others, it was built round its harbour like the seats of an ancient theatre round the orchestra, that is, fan-fashion like Karlsruhe. However, this case is doubtful. Rhodes was laid out in 408 B.C., thirty-five years after the planting of Thurii and seventy years after the approximate date of the birth of Hippodamus. It is conceivable but not altogether probable that Hippodamus was still planning towns in his extreme old age, nor is it, on political grounds, very likely that he would be planning in Rhodes. As, however, we do not know the real date of his birth, and as Strabo does not specifically mention his name, certainty is unattainable.[[18] ]

If we cannot tell exactly how Hippodamus planned cities or exactly which he planned, still less do we know how far town-planning on his or on any theory came into general use in his lifetime or indeed before the middle of the fourth century. Few Greek cities have been systematically uncovered, even in part. Fewer still have revealed street-planning which can be dated previous to that time. It does not follow, when we find streets in the ruins of an ancient city, that they must belong to its earliest period. That is not true of towns in any age, modern or mediaeval, Roman or Greek. Some Greek cities were founded in early times, were rebuilt in the Macedonian period, and again rebuilt in the Roman period. Without minute excavation it may be impossible to assign the town-plan of such a place to its proper place among these three periods.

We have, however, at Selinus in Sicily and Cyrene on the north coast of Africa, two cases which may belong to the age of Hippodamus. They are worth describing, since they illustrate both the difficulty of reaching quite certain conclusions and also the system which probably did obtain in the later fifth and the early fourth century.

Selinus (fig. 3).

At Selinus the Italian archaeologists discovered some years ago, in the so-called Acropolis, a town of irregular, rudely pear-shaped outline with a distinct though not yet fully excavated town-plan. Two main thoroughfares ran straight from end to end and crossed at right angles (fig. 3), the longer of these thoroughfares being just a quarter of a mile long and 30 ft. wide. From these two main streets other narrower streets (12-18 ft. wide) ran off at right angles; the result, though not chess-board pattern, is a rectangular town-plan. Unfortunately, it cannot be dated. Selinus was founded in 648 B.C., was destroyed in 409, then reoccupied and rebuilt, and finally destroyed for ever in 249. Its town-planning, therefore, might be as early as the seventh century B.C. Or (and this is the most probable conclusion) it may date from the days of Selinuntine prosperity just before 409, when the city was growing and the great Temple of Zeus or Apollo was rising on its eastern hill. Or again, though less probably, it may have been introduced after 400. We may conclude that we have here a clear case of town-planning and we may best refer it to the later part of the fifth century.[[19] ]
