Written in French, this thesis presents a comparative and intertextual study on the theme of « windows » in four poems by Charles Baudelaire, Stéphane Mallarmé, Marie Krysinska and Guillaume Apollinaire. Charles Baudelaire (1821-1867), Stéphane Mallarmé (1842 -1898), Marie Krysinska (1857-1908) and Guillaume Apollinaire (1880-1918) use « windows » as a common theme in their poetry. My study compares this common theme found in four poems: (1) “Les fenêtres” by Charles Baudelaire in Spleen de Paris XXXV, 1869. (2) “Les fenêtres” by Stéphane Mallarmé in Le Parnasse Contemporain, 1863/66. (3) “Les fenêtres” by Marie Krysinska in Rythmes pittoresques, 1890. (4) “Les fenêtres” by Guillaume Apollinaire in Calligrammes (1913-1916), 1918. I focus on what distinguishes these fours poems by following the evolution of poetical forms between symbolism and futurism/surrealism. The common theme (“windows”) provides an opportunity to better underline the formal heterogeneity which separates these different “poetical avenues”: with Baudelaire, the newness of prose poetry; with Mallarmé, the symbolist renewal of a more classic form; with Apollinaire, a form of simultaneity inspired by futurism. The comparative analysis brings to light the original value of the poem written by Krysinska, whose works have not greatly captivated the attention of critics.
