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. [85] Beloch, _Campanien_ (Berlin, 1879), p. 26; Capasso, _Napoli Greco-Romana_ (Napoli, 1905). The Forum, Market, and some other buildings marked by Capasso seem to me (and even to him or his editors) very dubious (p. 63). Two theatres (p. 82) and a Temple of the Dioscuri are better established. For plans see _Piante topogr. dei quartieri di Napoli_ 1861-5 (1:3,888) and _Pianta della città di N._ (Off. della Guerra, 1865), from which latter fig. 20 is adapted. [Illustration: FIG. 20. NAPLES. ADAPTED FROM A PLAN OF 1865. (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. [86] The limits are the Castel Capuano on the east, the Strada dell' Orticello on the north, the church of S. Pietro a Majella on the west, and on the south the churches of S. Marcellino and S. Severino.
