English summary: "Edison is the new Gutenberg. He invented the new printing," states Vachel Lindsay in 1914, in the first book ever devoted to cinema. This work is proof of the strong conviction of Lindsay: from the Platonic myth and the guesswork of parietal painting to the iconic and verbal beauties of Egyptian hieroglyphs, it encourages modern man to "think in pictures" and America to recognize in cinema the only possible grammar for the lexicon of its national imagination. This new edition of the seminal book (L'art du cinema) includes articles by Lindsay that appeared in The New Republic in 1917, as well as extensive extracts from the manuscript of a second, unpublished book.
