Of the causes that do concern the magnificency and greatness of a city

It now only resteth, having brought our city to that dignity and greatness which the condition of the site and other circumstances afford unto it, that we labour to conserve, to maintain and uphold the dignity and greatness of the same. And to speak all at a word, these helps may very well serve to do it: that is, justice, peace, and plenty. For justice assureth every man his own. Peace causeth tillage, trade and arts to flourish.

And plenty of food and victual sustaineth the life of man with ease and much contentment to him. And the people embrace nothing more gladly than plenty of corn. To conclude, all those things that cause the greatness of a city are also fit to conserve the same. For the causes, as well of the production of things as also of the conservation of them, are ever all one and the same, whatsoever they be.
