Passionate Journey, or My Book of Hours (French: Mon livre d'heures), is a wordless novel of 1919 by Flemish artist Frans Masereel. The story is told in 167 captionless prints, and is the longest and best-selling of the wordless novels Masereel made. It tells of the experiences of an early 20th-century everyman in a modern city.
Masereel's medium is the woodcut, and the images are in an emotional, allegorical style inspired by Expressionism. The book followed Masereel's first wordless novel, 25 Images of a Man's Passion (1918); both were published in Switzerland, where Masereel spent much of World War I. German publisher Kurt Wolff released an inexpensive "people's edition" of the book in Germany with an introduction by German novelist Thomas Mann, and the book went on to sell over 100,000 copies in Europe. Its success encouraged other publishers to print wordless novels, and the genre flourished in the interwar years.
Masereel followed the book with dozens of others, beginning with The Sun later in 1919. Masereel's work was lauded in the art world in the earlier half of the 20th century, but has since been neglected outside of Western comics circles, where Masereel's wordless novels are seen as anticipating the development of the graphic novel.
The story follows the life of a prototypical early 20th-century everyman after he enters a city. It is by turns comic and tragic: a sick woman cared for by the man loses her life; the man breaks wind at a group of businessmen; the man is rejected by a prostitute with whom he has fallen in love. He also takes trips to different locales around the world. In the end, the man leaves the city for the woods, raises his arms in praise of nature, and dies. His spirit rises from him, stomps on the heart of his dead body, and waves to the reader as it sets off across the universe.
