The barn swallow symbolises the coming of spring and thus love in the "Pervigilium Veneris", a late Latin poem. In his poem "The Waste Land", T. S. Eliot quoted the line ""Quando fiam uti chelidon tacere desinam?"" ("When will I be like the swallow, so that I can stop being silent?") This refers to the myth of Philomela in which she turns into a nightingale, and her sister Procne into a swallow. On the other hand, an image of the assembly of swallows for their southward migration concludes John Keats's ode "To Autumn".
