The scholar of English literature Marjorie Burns writes that one of the female Vala, Varda (Elbereth to the Elves) is sung to by the Elf-queen of Middle-earth Galadriel. Burns notes that Varda sits far off in Valinor on Oiolossë, looking from her mountain-peak tower in Aman towards Middle-earth and the Dark Tower of Sauron in Mordor: in her view, the white benevolent feminine symbol opposing the evil masculine symbol. Further, Burns suggests, Galadriel is an Elf from Valinor in the Blessed Realm, bringing Varda's influence with her to Middle-earth. This is seen in the phial of light that she gives to Frodo, and that Sam uses to defeat the evil giant spider Shelob: Sam invokes Elbereth when he uses the phial. Burns comments that Sam's request to the Lady sounds distinctly Catholic, and that the female principle, embodied in Varda of Valinor and Galadriel of Middle-earth, most clearly represents the charitable Christian heart.
