In this research, we try to shed light on the important place that the East occupies in the literary library in the world and particularly in France. Indeed, the East attracts much attention of men of letters since the Crusades (Chateaubriands, Lamartine, Hugo, Rousseau... etc.) and love for him grew with time especially in the 19th century (the era of progress and science). However, Baudelaire did not see the Orient as a geographical place but an idea and a literary aesthetic that adds beauty to his poetry. Through this research, we try to reveal the mechanism by which Baudelaire introduced the East in his Flowers speaking of his ability to link the concrete (the East) to the abstract (the beauty and perfection).
