 For some romantic poets, the nightingale even began to take on qualities of the muse.John Keats (1795–1821), in "Ode to a Nightingale" (1819) idealizes the nightingale as a poet who has achieved the poetry that Keats himself longs to write.Keats directly employs the Philomel myth in "The Eve of St. Agnes" (1820) where the rape of Madeline by Porphyro mirrors the rape of Philomela by Tereus.
