History of the Peloponnesian War

Accordingly they set to work in earnest, and having no iron tools, picked up stones, and put them together as they happened to fit, and where mortar was needed, carried it on their backs for want of hods, stooping down to make it stay on, and clasping their hands together behind to prevent it falling off;

sparing no effort to be able to complete the most vulnerable points before the arrival of the Lacedaemonians, most of the place being sufficiently strong by nature without further fortification.

Meanwhile the Lacedaemonians were celebrating a festival, and also at first made light of the news, in the idea that whenever they chose to take the field the place would be immediately evacuated by the enemy or easily taken by force; the absence of their army before Athens having also something to do with their delay.

The Athenians fortified the place on the land side, and where it most required it, in six days, and leaving Demosthenes with five ships to garrison it, with the main body of the fleet hastened on their voyage to Corcyra and Sicily.
