Isildur is a fictional character in J. R. R. Tolkien's Middle-earth, the elder son of Elendil, descended from Elros, the founder of the island Kingdom of Númenor. He fled with his father when the island was drowned, becoming in his turn King of Arnor and Gondor. He cut the Ring from Sauron's hand, but instead of destroying it, was corrupted by its power and claimed it for his own. He was killed by orcs, and the Ring was lost in the River Anduin. This set the stage for the Ring to pass to Gollum and then to Bilbo, as told in The Hobbit; that in turn provided the central theme, the quest to destroy the Ring, for The Lord of the Rings.
'Gladden' is an old name for the yellow iris which grows beside freshwater.
Harry Sinclair plays Isildur in Peter Jackson's The Lord of the Rings film trilogy.
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.
