Love, a powerful and puzzling emotion, has through the centuries evoked a wealth of images, metaphors and poetry, but seldom fostered the epistemological wish to discover its nature. The story of Cupid and Psyche, so often depicted in works of art, is of late origin (Apuleus), and therefore not a genuine myth. Nevertheless, it can be read as a cautionary tale, warning us that love will vanish if, like Psyche, driven by curiosity, we dare gaze upon its face.
