There was further a postern, also approached from the ridge, near the south-east corner. From the fortress, which stands more than two thousand feet above the sea, the view is magnificent, taking in the whole of the Athenian plain with Athens itself and Hymettus, and the sea with Salamis, Aegina, and the coast of Peloponnese. The high peak, now named Mount Pagania, which towers immediately to the north-east of Phyle in the form of a crescent-shaped wall of naked rock is probably the ancient Harma, which the augurs at Athens watched till they saw lightning flash about its summit, whereupon they sent the sacrifice to Delphi. Strabo expressly says that Harma was near Phyle. On its eastern side the peak descends in precipices into the deep glen, already mentioned, at the entrance of which is the monastery of Our Lady of the Defile. Farther up this glen than the monastery, at a height of some hundreds of feet above the torrent (the Potami) which traverses it, there is a cavern which is sometimes visited. The direct distance of this cavern from the monastery is only about a mile and a half. But in the glen the stream, hemmed in by precipices advancing from the mountains on both sides, has scooped out for itself between them a bed so profound and rugged that to scramble along it is impossible, even when the water is at its lowest. Hence in order to reach the cavern it is needful to make a long detour round the western flanks of Mount Pagania and to come down into the glen at a point a good deal higher up. Having done so we follow the glen downward past the place where another glen opens into it, bringing its tributary stream to swell the Potami. The cave is situated high up on the eastern side of the main glen, a little below the meeting of the waters. To clamber up the steep slope to it is far from easy. The mouth of the cave is so narrow that only one person can enter it at a time; it opens at the foot of a precipice darkened by overhanging trees and flanked by two crags which project like wings on either side. In the face of the rock to the right of the entrance into the cavern are some votive niches with worn inscriptions under them. Within the cave, which may be about a hundred paces deep, water dripping from the roof has formed large stalactites and has hollowed out basins in the floor. Broken lamps and potsherds have been found in it in considerable quantities, which, with the votive niches outside, prove that this secluded spot was an ancient sanctuary. It was most probably the Nymphaeum or sanctuary of the Nymphs, which Menander mentioned as being near Phyle. Here, too, the people of Phyle probably offered the sacrifices to Pan to which Aelian refers. For one of the inscriptions on the rock outside the cave sets forth that a certain Tychander caused workmen to put up the image of Pan beside the Celadon, and that sacrifices were offered by one Trophimianus. From this inscription we
