“London, thou art of townes A per se.
Soveraign of cities, semeliest in sight,
Of high renoun, riches, and royaltie;
Of lordis, barons, and many goodly knyght;
Of most delectable lusty ladies bright;
Of famous prelatis in habitis clericall;
Of merchauntis full of substaunce and myght:
London, thou art the flour of Cities all”

“Do you know what Agelisas said, when he was asked why the great city of Lacedomonie was not girded with walls? Because, pointing out the inhabitants and citizens of the city, so expert in military discipline and so strong and well armed: “Here,” he said, “are the walls of the city,” meaning that there is no wall but of bones, and that towns and cities can have no more secure nor stronger wall than the virtue of their citizens and inhabitants.”
—François Rabelais (1494–1553)
