Eärendil is the star-associated figure named in Tolkien’s poem “The Song of Eärendil.”
In The Lord of the Rings, the poem tells of Eärendil the Mariner, who sails into the West carrying a shining jewel. Tolkien’s wider mythology explains that Eärendil becomes a star or heavenly light visible in the skies of Middle-earth. His story links the ancient First Age with the later events involving Frodo and Sam.
The light associated with Eärendil is preserved in the phial Galadriel gives Frodo. Sam later uses it against Shelob, and the light becomes a symbol of hope in darkness. The name therefore connects poetry, cosmology, heroic history, and a practical object in the narrative.
Eärendil is sometimes confused with Elbereth, the Vala associated with the stars, or with Gil-galad, the Elven king mentioned in another poem. Beren is also a First Age hero, but he is not the figure named in this title.
