Thucydides is strictly correct both as regards official and literary usage. An examination of official inscriptions shows that down to the Peace of Antalcidas (387-6 B.C.) the Acropolis was officially known as _polis_[282]. The new form ‘in the Acropolis’ first appears in the year of the peace[283], and from then on is in regular use. In literature, both in prose and verse, _polis_ is still uniformly used after a local preposition, _e.g._ towards the _polis_, in the _polis_; but when there is no local preposition the word acropolis is employed. Thus, in the _Knights_ of Aristophanes[284], when the Sausage-Seller sees the Goddess herself coming from the _polis_ with her owl perched on her, and there is no shadow of doubt that Athena is coming from the Acropolis; but Lysistrata[285] says, ‘to-day we shall seize the Acropolis,’ where there is no local preposition, though the sense would have been clear with _polis_. As Dr Wyse[286] has pointed out, it was easy for the word _polis_ to go on being used for the Acropolis, because the Athenians had another word (ἄστυ), which they used in such phrases as ‘in town,’ ‘to town.’ * * * * * We have learnt from Thucydides all he has to tell us, and in the light of recent excavations he seems to have spoken clearly enough. The limits of his ancient city have been confirmed by the discovery of the old Pelasgic fortifications. We have seen with our own eyes two of the ancient sanctuaries which lay _towards_ his city, the Pythion and the sanctuary of Dionysos-in-the-Marshes; and from literary evidence inferred the two others, the Olympieion and the sanctuary of Ge. We have noted that, in the order in which Thucydides names them, they occur in succession from East to West; and, most convincing of all, near to the last-named sanctuary we have found Nine-Spouts, and not only Nine-Spouts, but the old Fair-Fount that was before it. Thus all seems clear and simple; Thucydides, Pausanias, and modern excavations tell the same harmonious tale. [Illustration: FIG. 46. From _Antike Denkmäler_ II. 37.] CONCLUSION. Having now stated what we believe to be the truth respecting the ancient burgh of Athens, its nature and limits and the position of its early Sanctuaries, we have still, in accordance with the plan proposed at the outset (p. 4), to examine other and, as we believe, erroneous views. These views are widely current in manuals and guide-books and are supported by names[287] that command respect. A study of the genesis of errors so wide-spread and deep-rooted may not be unprofitable. The sources of error seem to us fourfold, as follows: 1. _The lie of the modern town._ 2. _A misunderstanding of the text of Thucydides._ 3. _The duplication of certain sanctuaries and, closely connected with this_, 4. _Confusion as to Kallirrhoë and Enneakrounos._ 1. _The lie of the modern town._
