The unfolding of eroticism always has been controlled socially; its expression forbidden for the women and accepted for the men. Ernestina de Champourcín’s poetry is an example of the presence of eroticism and the Avant-Garde in Spanish poetry. Champourcín becomes a member of the Generation of ‘27 after appearing in the prologue of Gerardo Diego’s anthology, Poesía Española Contemporßnea (1934). According to this thesis, the shortage of studies on her work is due to her exile, not to the Spanish Civil War. The exposition celebrates the life and work of Champourcín and studies the relationship between the Avant-Garde and sensuality in her poetry and in poems of Pedro Salinas and Vicente Aleixandre. It compares their individual handling of the Avant-Garde, the sexual act, and love, and concludes that Champourcín’s poetry is as Avant-Garde and erotic as the works of her companions of the Generation of ‘27.
