CHAPTER 108

The Athenians were drawn up in order of battle in a sacred close belonging to Hercules, when they were joined by the Plataeans, who came in full force to their aid. Some time before, the Plataeans had put themselves under the rule of the Athenians; and these last had already undertaken many labours on their behalf. The occasion of the surrender was the following. The Plataeans suffered grievous things at the hands of the men of Thebes; so, as it chanced that Cleomenes, the son of Anaxandridas, and the Lacedaemonians were in their neighbourhood, they first of all offered to surrender themselves to them. But the Lacedaemonians refused to receive them, and said:

"We dwell too far off from you, and ours would be but chill succour. Ye might oftentimes be carried into slavery before one of us heard of it. We counsel you rather to give yourselves up to the Athenians, who are your next neighbours, and well able to shelter you."

This they said, not so much out of good will towards the Plataeans as because they wished to involve the Athenians in trouble by engaging them in wars with the Boeotians. The Plataeans, however, when the Lacedaemonians gave them this counsel, complied at once; and when the sacrifice to the Twelve Gods was being offered at Athens, they came and sat as suppliants about the altar, and gave themselves up to the Athenians. The Thebans no sooner learnt what the Plataeans had done than instantly they marched out against them, while the Athenians sent troops to their aid. As the two armies were about to join battle, the Corinthians, who chanced to be at hand, would not allow them to engage; both sides consented to take them for arbitrators, whereupon they made up the quarrel, and fixed the boundary-line between the two states upon this condition: to wit, that if any of the Boeotians wished no longer to belong to Boeotia, the Thebans should allow them to follow their own inclinations. The Corinthians, when they had thus decreed, forthwith departed to their homes: the Athenians likewise set off on their return; but the Boeotians fell upon them during the march, and a battle was fought wherein they were worsted by the Athenians. Hereupon these last would not be bound by the line which the Corinthians had fixed, but advanced beyond those limits, and made the Asopus the boundary-line between the country of the Thebans and that of the Plataeans and Hysians. Under such circumstances did the Plataeans give themselves up to Athens; and now they were come to Marathon to bear the Athenians aid.
