Elendil is a fictional character in J. R. R. Tolkien's legendarium. He is mentioned in The Lord of the Rings, The Silmarillion and Unfinished Tales. He was the father of Isildur and Anárion, last lord of Andúnië on the island of Númenor, and having escaped its downfall by sailing to Middle-earth, became the first High King of Arnor and Gondor. In the Last Alliance of Men and Elves, Elendil and Gil-galad laid siege to the Dark Lord Sauron's fortress of Barad-dûr, and fought him hand-to-hand for the One Ring. Both Elendil and Gil-galad were killed, and Elendil's son Isildur took the Ring for himself.
Tolkien compared Elendil to the Biblical Noah, who similarly escaped from the wreck of a civilisation by ship. Fresco in San Maurizio al Monastero Maggiore, Milan
Elendil was played by Peter McKenzie in Peter Jackson's 2001 film The Fellowship of the Ring, fighting a gigantic Sauron to the death.
Tolkien's legendarium is the body of J. R. R. Tolkien's mythopoeic writing, unpublished in his lifetime, that forms the background to his The Lord of the Rings, and which his son Christopher summarized in his compilation of The Silmarillion and documented in his 12-volume series The History of Middle-earth. The legendarium's origins reach back to 1914, when Tolkien began writing poems and story sketches, drawing maps, and inventing languages and names as a private project to create a unique English mythology. The earliest story drafts are from 1916; he revised and rewrote these for most of his adult life.
Tolkien went to great lengths to present his work as a collection of documents "within the fictional world", including preparing facsimile pages from The Book of Mazarbul to support the story (it was intended for The Lord of the Rings) and to bring readers into his fantasy.
