Whoever had, at that period, observed the Greeks exposed on one side to the open sea, and on the other to the Spaniards, a fierce and warlike race, would have wondered by what cause they were preserved.

Deficient in strength, they guarded against danger by regular discipline; of which, among even more powerful people, the best preservative is fear.

That part of the wall which faced the country, they kept strongly fortified, having but one gate, at which some one of the magistrates was continually on guard.

During the night, a third part of the citizens kept watch on the walls, posting their watches, and going their rounds, not merely from the force of custom, or in compliance with the law, but with as much vigilance as if an enemy were at their gates.

They never admitted any Spaniard into the city, nor did they go outside the walls without precaution.
