De Agricultura

For as fishermen let down their nets at times to the most extraordinary depths, comprehending a vast surface of the sea in their circle, in order to catch the greatest possible number of fish enclosed within their nets, like people shut up within the walls of a besieged city; so in the same manner the greatest part of men having extended their universal nets to take everything, as the poets somewhere say, not only over the parts of the sea, but also over the whole nature of earth, and air, and water, seek to catch everything from every quarter for the enjoyment and attainment of pleasure.
