A Elbereth Gilthoniel is an Elvish hymn to Varda (Sindarin: Elbereth) in J. R. R. Tolkien's The Lord of the Rings. It is the longest piece of Sindarin in The Lord of the Rings. It is not translated in the main text where it is first presented. The poem, written in iambic tetrameters, has been likened to a Roman Catholic Marian hymn. Among the musical renderings of the poem, the earliest is Donald Swann's, published in his song cycle The Road Goes Ever On, while The Tolkien Ensemble recorded four different renditions.
