When we turn to examine actual remains of the Pelasgikon on the south slope of the Acropolis (Fig. 2), we are met by disappointment. Of all the various terraces and supporting walls, only one fragment (P) can definitely be pronounced Pelasgian. The remaining walls seen in Fig. 16 date between the seventh and the fifth centuries. The walls marked G in the plan in Fig. 16, but purposely omitted in Fig. 2, are of good polygonal masonry, and must have been supporting walls to the successive terraces of the Pelasgikon; they are probably of the time of Peisistratos[63], but may even be earlier. It is important to note that though not ‘Pelasgic’ themselves they doubtless supplanted previous ‘Pelasgic’ structures. The line followed by the ancient road must have skirted the outermost wall of the Pelargikon; later it was diverted in order to allow of the building of the Odeion of Herodes Atticus. The Pelasgikon of Lucian’s day only extended as far as the Asklepieion; the earlier fortification must have included what was later the Asklepieion[64], as it would need to protect the important well within that precinct. * * * * * Thucydides has stated the limits of the ancient city, ‘_what is now the citadel was the city together with what is below it towards about south_.’ We now-a-days should not question his statement. The remains of the Pelasgian fortifications disclosed by excavation amply support his main contention, namely, that _what is now the citadel was the city_, the conformation of the hill and literary evidence justify his careful ‘addendum’ _together with what is below it towards about south_. But, as noted before, the readers of Thucydides were not in our position, they knew less about the boundaries of the ancient city, and though they probably knew fairly well the limits of the Pelasgikon, even that was becoming rather a matter of antiquarian interest. Above all, they were citizens of the larger city of Themistocles, the Dipylon was more to them than the Enneapylon. Thucydides therefore feels that the truth about the ancient city needs driving home. He proceeds to give evidence for what was, he felt, scarcely self-evident. If we feel that the evidence is somewhat superfluous, we yet welcome it because incidentally he thereby gives us much and interesting information as to the sanctuaries of ancient Athens. The evidence is, as above stated (p. 8), fourfold. CHAPTER II. THE SANCTUARIES IN THE CITADEL. τὰ γὰρ ἱερὰ ἐν αὐτῇ τῇ ἀκροπόλει καὶ ἄλλων θεῶν ἐστί. _There are sanctuaries in the citadel itself, those of other deities as well (as The Goddess)._
