Galadriel [SEP] Introduction
Her daughter Celebrían was the wife of Elrond and mother of Arwen, Elladan, and Elrohir. Tolkien describes Galadriel as "the mightiest and fairest of all the Elves that remained in Middle-earth" (after the death of Gil-galad) and the "greatest of elven women". The Tolkien scholar Tom Shippey has written that Galadriel represented Tolkien's attempt to re-create the kind of elf hinted at by surviving references in Old English. He has compared his elves also to those in a Christian Middle English source, "The Early South English Legendary", where the elves were angels. Another scholar, Marjorie Burns, compares Galadriel in multiple details to Rider Haggard's heroine , and to Tennyson's The Lady of Shalott, both being reworked figures of Arthurian legend.
