This article focuses on artistic and aesthetic practices within the idealist and symbolist movements of the late 19th century in France. It investigates how artists and art critics embraced androgynous imaginaries derived from Greco-Roman antiquity and the Platonic myth, transforming them into tools for social and sexual emancipation and giving rise to a proto-queer vision. An analysis of the art of Alexandre Séon, Odilon Redon, Jeanne Jacquemin, and Léonard Sarluis, in conjunction with the symbolist theories of Joséphin Péladan, Gabriel-Albert Aurier, and Émile Verhaeren, reveals an idealistic pursuit grounded in the union of the masculine and the feminine through the act of creation. Through the examination of artworks, contemporary critical discourse, and the personal correspondence of these art figures, this study posits that the androgyne serves as a heuristic model for a queer art history. The ideal androgyne, as theorized in Freud’s psychoanalytic writings, can function as a methodological paradigm in art studies as a tool for visualizing and conceptualizing homosexuality in art.
