The walls of Corinth, overthrown by an earthquake, and the mouldering bulwarks of Athens and Plataea, were carefully restored; the Barbarians were discouraged by the prospect of successive and painful sieges: and the naked cities of Peloponnesus were covered by the fortifications of the Isthmus of Corinth.

At the extremity of Europe, another peninsula, the Thracian Chersonesus, runs three days' journey into the sea, to form, with the adjacent shores of Asia, the Straits of the Hellespont.
