Paul Klee, Die Zwitscher-Maschine [Twittering Machine], 1922 (MOMA).
Walter Benjamin writes:
The messianic world is the world of complete and integral actuality. Only in the messianic realm does a universal history exist. Not as written history, but as festively enacted history. This festival is purified of all celebration. There are no festive songs. Its language is liberated prose - prose which has burst the fetters of script and is understood by all people (as the language of birds is understood by those born on Sundays).
