What a city is, and what the greatness of a city is said to be

A city is said to be an assembly of people, a congregation drawn together to the end they may thereby the better live at their ease in wealth and plenty. And the greatness of a city is said to be, not the largeness of the site or the circuit of the walls, but the multitude and number of the inhabitants and their power. Now men are drawn together upon sundry causes and occasions thereunto them moving: some by authority, some by force, some by pleasure, and some by profit that proceedeth of it.
