There are also other ancient temples in this quarter. The fountain too, which, since the alteration made by the tyrants, has been called Enneacrounos, or Nine Pipes, but which, when the spring was open, went by the name of Callirhoe, or Fairwater, was in those days, from being so near, used for the most important offices. Indeed, the old fashion of using the water before marriage and for other sacred purposes is still kept up. Again, from their old residence in that quarter, the citadel is still known among Athenians as the city.
The Athenians thus long lived scattered over Attica in independent townships. Even after the centralization of Theseus, old habit still prevailed; and from the early times down to the present war most Athenians still lived in the country with their families and households, and were consequently not at all inclined to move now, especially as they had only just restored their establishments after the Median invasion. Deep was their trouble and discontent at abandoning their houses and the hereditary temples of the ancient constitution, and at having to change their habits of life and to bid farewell to what each regarded as his native city.
When they arrived at Athens, though a few had houses of their own to go to, or could find an asylum with friends or relatives, by far the greater number had to take up their dwelling in the parts of the city that were not built over and in the temples and chapels of the heroes, except the Acropolis and the temple of the Eleusinian Demeter and such other Places as were always kept closed. The occupation of the plot of ground lying below the citadel called the Pelasgian had been forbidden by a curse; and there was also an ominous fragment of a Pythian oracle which said:
Leave the Pelasgian parcel desolate, Woe worth the day that men inhabit it!
Yet this too was now built over in the necessity of the moment. And in my opinion, if the oracle proved true, it was in the opposite sense to what was expected. For the misfortunes of the state did not arise from the unlawful occupation, but the necessity of the occupation from the war; and though the god did not mention this, he foresaw that it would be an evil day for Athens in which the plot came to be inhabited. Many also took up their quarters in the towers of the walls or wherever else they could. For when they were all come in, the city proved too small to hold them; though afterwards they divided the Long Walls and a great part of Piraeus into lots and settled there.
All this while great attention was being given to the war; the allies were being mustered, and an armament of a hundred ships equipped for Peloponnese. Such was the state of preparation at Athens.
Meanwhile the army of the Peloponnesians was advancing. The first town they came to in Attica was Oenoe, where they to enter the country. Sitting down before it, they prepared to assault the wall with engines and otherwise. Oenoe, standing upon the Athenian and Boeotian border, was of course a walled town, and was used as a fortress by the Athenians in time of war. So the Peloponnesians prepared for their assault, and wasted some valuable time before the place. This delay brought the gravest censure upon Archidamus. Even during the levying of the war he had credit for weakness and Athenian sympathies by the half measures he had advocated; and after the army had assembled he had further injured himself in public estimation by his loitering at the Isthmus and the slowness with which the rest of the march had been conducted. But all this was as nothing to the delay at Oenoe. During this interval the Athenians were carrying in their property; and it was the belief of the Peloponnesians that a quick advance would have found everything still out, had it not been for his procrastination. Such was the feeling of the army towards Archidamus during the siege. But he, it is said, expected that the Athenians would shrink from letting their land be wasted, and would make their submission while it was still uninjured; and this was why he waited.
But after he had assaulted Oenoe, and every possible attempt to take it had failed, as no herald came from Athens, he at last broke up his camp and invaded Attica. This was about eighty days after the Theban attempt upon Plataea, just in the middle of summer, when the corn was ripe, and Archidamus, son of Zeuxis, king of Lacedaemon, was in command. Encamping in Eleusis and the Thriasian plain, they began their ravages, and putting to flight some Athenian horse at a place called Rheiti, or the Brooks, they then advanced, keeping Mount Aegaleus on their right, through Cropia, until they reached Acharnae, the largest of the Athenian demes or townships. Sitting down before it, they formed a camp there, and continued their ravages for a long while.
The reason why Archidamus remained in order of battle at Acharnae during this incursion, instead of descending into the plain, is said to have been this. He hoped that the Athenians might possibly be tempted by the multitude of their youth and the unprecedented efficiency of their service to come out to battle and attempt to stop the devastation of their lands. Accordingly, as they had met him at Eleusis or the Thriasian plain, he tried if they could be provoked to a sally by the spectacle of a camp at Acharnae. He thought the place itself a good position for encamping; and it seemed likely that such an important part of the state as the three thousand heavy infantry of the Acharnians would refuse to submit to the ruin of their property, and would force a battle on the rest of the citizens. On the other hand, should the Athenians not take the field during this incursion, he could then fearlessly ravage the plain in future invasions, and extend his advance up to the very walls of Athens.
