(M119) About five miles to the north-east of the Corycian caverns, but divided from them by many deep gorges and impassable rocks, is another and very similar chasm. It may be reached in about an hour and a quarter from the sea by an ancient paved road, which ascends at first very steeply and then gently through bush-clad and wooded hills. Thus you come to a stretch of level ground covered with the well-preserved ruins of an ancient town. Remains of fortresses constructed of polygonal masonry, stately churches, and many houses, together with numerous tombs and reliefs, finely chiselled in the calcareous limestone of the neighbourhood, bear witness to the extent and importance of the place. Yet it is mentioned by no ancient writer. Inscriptions prove that its name was Kanyteldeis or Kanytelideis, which still survives in the modern form of Kanidiwan. The great chasm opens in the very heart of the city. So crowded are the ruins that you do not perceive the abyss till you are within a few yards of it. It is almost a complete circle, about a quarter of a mile wide, three-quarters of a mile in circumference, and uniformly two hundred feet or more in depth. The cliffs go sheer down and remind the traveller of the great quarries at Syracuse. But like the Corycian caves, the larger of which it closely resembles, the huge fissure is natural; and its bottom, like theirs, is overgrown with trees and vegetation. Two ways led down into it in antiquity, both cut through the rock. One of them was a tunnel, which is now obstructed; the other is still open. Remains of columns and hewn stones in the bottom of the chasm seem to show that a temple once stood there. But there is no cave at the foot of the cliffs, and no stream flows in the deep hollow or can be heard to rumble underground. A ruined tower of polygonal masonry, which stands on the southern edge of the chasm, bears a Greek inscription stating that it was dedicated to Olbian Zeus by the priest Teucer, son of Tarkuaris. The letters are beautifully cut in the style of the third century before Christ. We may infer that at the time of the dedication the town belonged to the priestly kings of Olba, and that the great chasm was sacred to Olbian Zeus.(463)
