LXVIII. THE PLAIN OF MEGALOPOLIS.—Megalopolis stood in the great western plain of Arcadia, which, like the great eastern plain of Mantinea and Tegea, extends in a direction from north to south. In natural beauty the plain of Megalopolis is far superior to its eastern neighbour. The latter is a bare monotonous flat, unrelieved by trees or rivers, and enclosed by barren mountains, so that its general aspect is somewhat dreary and depressing; only towards its northern end do the mountains rise in grander masses and with more picturesque outlines. The plain of Megalopolis, on the other hand, is surrounded by mountains of fine and varied outlines, some of the slopes of which are clothed with wood, and the surface of the plain itself is diversified with copses and undulating downs and hillocks, refreshed by numerous streams shaded with plane-trees, and watered by the broad though shallow stream of the Alpheus winding through its midst. The scenery, in contrast to that of the eastern plain, is eminently bright, smiling, and cheerful. It is, perhaps, seen at its best after rain on a fine morning in early summer. The vegetation is then green, the air pellucid, the outlines of the environing mountains are sharp and clear, and their tints vary from deep purple to lilac. LXIX. THE CAVE OF THE BLACK DEMETER.—The cave of the Black Demeter has been identified with a small cavern in the glen of the Neda, about an hour’s walk to the west of Phigalia. The place is known in the neighbourhood as the _stomion tes Panagias_ or Gully of the Virgin. To reach the cavern it is necessary to descend into the ravine by a steep and narrow path which affords very little foothold and overhangs depths which might turn a weak head. At the awkward places, however, it is generally possible to hold on to bushes or rocks with the hands. Thus we descend to the bed of the river, which here rushes roaring along at the bottom of the narrow wooded ravine, the precipitous sides of which tower up on either hand to an immense height. The cave is situated in the face of a prodigious cliff on the north side of the ravine, about a hundred feet or so above the bed of the river, from which it is accessible only by a narrow and difficult footpath. The ravine at this point sweeps round in a sharp curve, and the cavern is placed just at the elbow of the bend. On the opposite side of the lyn, some fifty feet or so away, a great crag, its sides green with grass and trees wherever they can find a footing, soars up to a height about as far above the cavern as the cavern is above the stream. Hills close the view both up and down the glen; those at the upper end are high, steep, and wooded.
