Further south, on the edge of the Haurân, stood the town of Gerasa. This too, like Apamea, was built by the Macedonians and flourished not only in their days but during the following Roman age. Its general outline was ovoid, its greatest diameter three quarters of a mile, its area some 235 acres--nearly the same with Roman Cologne and Roman Cirencester. Its streets resembled those of Apamea. A colonnaded highway ran straight through from north to south; two other streets crossed at right angles, and its chief public buildings, the Temple of the Sun and three other temples, two theatres and two public baths, stood near these three streets (fig. 10). Again the evidence proves rectangular town-planning in broad outline; excavation alone can tell the rest.[37] [37] _Zeitschrift des deutschen Palãstina-Vereins_, xxv (1902), plate 6; Bãdeker, _Palestine and Syria_ (1906), p. 140. For the neighbouring Bostra, see p. 136. [Illustration: FIG. 10. GERASA] In the towns just described a distinctive feature is the 'chess-board' pattern of streets and rectangular house-blocks. That, of course, is the feature which most concerns us here. It may not have looked so predominant to their builders and inhabitants. The towns which the Macedonians founded were not seldom rich and large; several were the capitals of powerful and despotic rulers. In such towns we expect great public buildings, temples, palaces. It is not surprising if sometimes those who reared them cared solely for the spectacular grouping of magnificent structures and forgot the private houses and the general plan of the town. _Pergamum_. One such instance from the Macedonian age, perhaps the most instructive which we could ever hope to get,[38] is Pergamum, in the north-west of Asia Minor. This has been thoroughly explored by German science; its remains are superb; its chief buildings date from an age when town-planning had grown familiar to the Greek world. About 300 B.C. it was a hill-town where a Macedonian chief could bestow a war-chest. It grew both populous and splendid in the third and second centuries B.C. under the Attalid kings; later builders, Augustus or Trajan or other, added little either to its general design or to its architectural glory. The dominant idea was that of a semi-circle of great edifices, crowning the crest and inner slopes of a high crescent-shaped ridge. Near the northern and highest end of this ridge stood the palace of the Attalid princes, afterwards buried beneath a temple in honour of Trajan. Next, to the south, was the Library--with stores of papyri worth more perhaps to the world than all the architecture of Pergamon. The middle of the crescent held the shrine of Athena, goddess of Pergamon, and beside it the Altar of Zeus the Saviour, gigantic in size, splendid with sculpture, itself the equal of an Acropolis. Lastly, the southern or lower end of the ridge bore a temple of Dionysus and an Agora for Assemblies.
