"Lord Leighton had painted her, distraught and floating, a golden figure in a tunnel of darkness"

 Frederic Leighton (1830 - 1896) was an English artist and sculptor of the Victorian era. He associated with the Pre-Raphaelite Brotherhood and is possibly best known for his painting Flaming June. In 1891 he painted The Return of Persephone, which shows Persephone (Proserpina) being helped by the god Hermes to return to her mother Demeter, after being freed from the underworld.
