Famous quotes containing the word cities:
“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”
—William Dunbar (c. 1465–c. 1530)
“Today as in the time of Pliny and Columella, the hyacinth flourishes in Wales, the periwinkle in Illyria, the daisy on the ruins of Numantia; while around them cities have changed their masters and their names, collided and smashed, disappeared into nothingness, their peaceful generations have crossed down the ages as fresh and smiling as on the days of battle.”
—Edgar Quinet (1803–1875)
“Just as language has no longer anything in common with the thing it names, so the movements of most of the people who live in cities have lost their connexion with the earth; they hang, as it were, in the air, hover in all directions, and find no place where they can settle.”
—Rainer Maria Rilke (1875–1926)
