Note 62 — Chapter XXX · CORINTH.

It was the favourite plan of the Peloponnesian states in the Persian war to fortify the Isthmus and leave all Northern Greece at the mercy of the Persians; but this plan was abandoned owing to the declaration of the Athenians that, if it was persisted in, they would make terms with the Persians. A wall, of course, would have been useless, if the fleet of the enemy were free to land an army wherever it pleased. The work, however, was begun, though never completed.
