Very few remains of the ancient city of Mantinea are to be seen, but the lower courses of the encircling walls, measuring more than two and a half miles in circumference, are plainly visible, with eight different gates and more than 120 towers, separated by intervals of fully 80 feet, while the course of the Ophis can also be traced, which served apparently as a moat, with its two arms running round the city. In 1887 three marble slabs were discovered in the floor of a Byzantine church within the walls, with reliefs representing the musical contest between Marsyas and Apollo, which have been identified with those mentioned by Pausanias as adorning a pedestal supporting images of Latona and her children, by Praxiteles. In the present aspect of the place, which is very much of the nature of a swamp, there is little to justify its ancient reputation as the “lovely city” mentioned in Homer. Tegea and Mantinea and another ancient city in the neighbourhood (Pallantion) are commemorated in the city of Tripoliza (or Tripolis, the threefold city), which was founded by the Turks about two hundred years ago. [Illustration: MEGALÓPOLIS IN ARCADIA The east ramp of the Theatre is in the foreground to the left, from which we see remains of the proscenium and colonnade. Beyond are a few drums of columns, probably belonging to the Thersilion or Town Hall. The river Helisson shows in the distance. Sunset.] Tripoliza is the only large town in Arcadia, having a population of more than 10,000, with a thriving trade. It is also the seat of a bishopric, and contains one of the handsomest modern churches in Greece, built of marble, with a lofty tower recently added. The elevation of the city, like that of the plain generally, is fully 2000 feet above the sea.
