This article examines the image of ‘flowers of evil’ as an imago image — an imaginary image of a real object. The term ‘imago’ was first used in this sense by Carl Jung in 1912. The work proposes a novel approach to investigating the image of ‘flowers of evil’. The comparative historical, analytical and psychoanalytic methods of text examination revealed that, in his novel À rebours, Huysmans espouses Baudelaire’s celebrated image, representing it primarily as a notion of something bizarre, extraordinary, transmuted and dangerous. This is achieved through the reception of the image of ‘flowers of evil’ embodied by Huysmans in a series of vegetative appearances, such as the collection of exotic plants, the lotus in the hands of Salome and the nidularium seen in a dream. It is concluded that Huysmans uses phytonymic images to demonstrate his belief that his decadent contemporaries, personified in the character of Jean Desessent, perceive Baudelaire’s work superficially, inaccurately and too literally, making them accomplices in the ‘burial’ of everything associated with ‘old’ values. Therefore, as a poetic image, Baudelaire’s ‘flowers of evil’ align with the explored ‘imago’ methodology as they generate multiple interpretive chains representing independent acts of creativity.
