This gate facing south-west stands on the summit of the hill, and is but one. Kleidemos (p. 11) tells us that the Pelargikon had nine gates. That there should be nine gates _round_ the Acropolis is unthinkable, such an arrangement would weaken the fortification, not strengthen it. The successive gates must somehow have been arranged one inside the other, and the fortifications would probably be in terrace form. The west slope of the Acropolis lends itself to such an arrangement, and in Turkish days this slope was occupied by a succession of redoubts (Fig. 14). Fortified Turkish Athens is in some ways nearer to the old Pelasgian fortress than the Acropolis as we see it to-day. We shall probably not be far wrong if we think of the approach to the ancient citadel as a winding way (Fig. 15), leading gradually up by successive terraces, passing through successive fortified gates[55], and reaching at last the topmost _propylon_ which faced south-west. These terraces, gates, fortifications, covering a large space, the limits of which will presently be defined, formed a whole known from the time of Thucydides to that of Lucian as the Pelargikon or Pelasgikon. [Illustration: FIG. 15.] * * * * * Lucian indeed not only affords our best evidence that, down to Roman days, a place called the Pelasgikon existed below the Acropolis, but is also our chief literary source for defining its limits. We expect those limits to be wide, otherwise the refugees would not have crowded in. The passages about the Pelasgikon in Lucian are two. First in the ‘Double Indictment[56],’ Dike, standing on the Acropolis, sees Pan approaching, and asks who the god is with the horns and the pipe and the hairy legs. Hermes answers that Pan, who used to dwell on Mt Parthenion, had for his services been honoured with a cave below the Acropolis ‘a little beyond the Pelasgikon.’ There he lives and pays his taxes as a resident alien. The site of Pan’s cave is certainly known; close below it was the Pelasgikon. This marks the extreme limit of the Pelasgikon to the north, for the sanctuary of Aglauros (p. 81) by which the Persians climbed up was unquestionably outside the fortifications. Herodotus[57] distinctly says, ‘In front then of the Acropolis, but behind the gates and the ascent, where neither did anyone keep guard, nor could it be expected that anyone could climb up there, some of them ascended near the sanctuary of Aglauros, daughter of Kekrops, though the place was precipitous.’
