It was the secrets and stories of the quiet corners that fascinated Guillaume Apollinaire (1880-1918) about Paris. As a flâneur in Paris, he focused on the pre-modern city of eccentrics, which was threatened with disappearance, and on the ugly, industrial manifestations of modernity. The excursions presented here, which appeared shortly after Apollinaire's death, reveal his preference for the surprising, the lawless, for the poetic allure of torn posters and graffiti, and for the overlays of reality and fiction. On the occasion of the hundredth anniversary of the poet's death on November 9, 2018, the book is being released in a new edition. Apollinaire was a poet, indeed a person, à propos de tout et de rien. He immersed himself in the moment with such intense feeling and yet, at the same time, found such peculiar pleasure in the past that he was much more akin to any poets or artists of the great Ano.
