History of the Peloponnesian War

But the Plataean envoys went to the Athenians and after consulting with them returned with the following message to the people at home: "

The Athenians assure you, Plataeans, that as in times past, since you became their allies,[*](About 520 B.C. cf. Thuc. 3.68.5.) they have never on any occasion deserted you when you were being wronged, so now they will not suffer you to be wronged, but will assist you with all their might. They therefore adjure you, by the oaths which your fathers swore, not to break off the alliance."

When the envoys reported this answer, the Plataeans determined not to betray the Athenians, but to endure even to see their lands laid waste, if need be, and to suffer whatever else might happen; further, that no one should thereafter leave the city, but that the answer should be given from the walls that they found it impossible to do what the Lacedaemonians proposed.

And when they had made answer, thereupon king Archidamus first stood forth calling the gods and heroes of the country to witness in the following words: "Ye gods and heroes who protect the land of Plataea, be our witnesses that we did no wrong in the beginning, but only after the Plataeans first abandoned the oath we all swore did we come against this land, where our fathers, invoking you in their prayers, conquered the Persians, and which you made auspicious for the Hellenes to fight in, and that now also, if we take any measures, we shall be guilty of no wrong; for though we have made them many reasonable proposals we have failed. Grant therefore your consent, that those be punished for the wrong who first began it, and that those obtain their revenge who are seeking to exact it lawfully."
