HE ATHENIANS, on their return to Attica, after the defeat of the Persians, found their city ruined and their country desolate. They began to rebuild their city on a larger scale than before, and to fortify it with a wall. Those allies to whom the increasing maritime power of Athens was an object of suspicion, and especially the AEginetans, to whom it was more particularly formidable, beheld her rising fortifications with dismay. They endeavoured to inspire the Lacedaemonians with their fears, and urged them to arrest the work. But though Sparta shared the jealousy of the allies, she could not with any decency interfere by force to prevent a friendly city from exercising a right inherent in all independent states. She assumed therefore the hypocritical garb of an adviser and counsellor. Concealing her jealousy under the pretence of zeal for the common interests of Greece, she represented to the Athenians that, in the event of another Persian invasion, fortified towns would serve the enemy for camps and strongholds, as Thebes had done in the last war; and proposed that the Athenians should not only desist from completing their own fortifications, but help to demolish those which already existed in other towns.
