Focusing on the founding figures of British aestheticism, Algernon Charles Swinburne and Walter Pater, this chapter discusses how they embraced the identity of the aesthetic olfactif, the cultivation of scent sensitivity, and the notion of the perfumed atmosphere produced by individual writers and literary or cultural schools, with this reflected in their influential critical prose. While Swinburne’s notorious Poems and Ballads (1866) apparently revels in heady perfumes, his own taste for light airy florals and dislike of musk clearly emerges in his subsequent poetry and prose, although his associations with his favoured scents are anything but conventional. Pater, another lover of delicate floral fragrance, refines Swinburne’s perception of the ‘scent’ of literature into a subtler critical language. His influential notion of the literary work’s ‘scented essence’ was adopted by admirers like Wilde and Symons, while his own writing was noted for its unmistakable ‘perfume’.
