what is the raven poem about

"The Raven" is a narrative poem by Edgar Allan Poe, first published in 1845. It tells the story of a distraught lover, often identified as a student, who is visited by a talking raven while lamenting the loss of his love, Lenore. The poem is noted for its musicality, stylized language, and supernatural atmosphere. The raven's constant repetition of the word "Nevermore" further antagonizes the protagonist.

Poe's careful crafting of the poem is described in his 1846 essay "The Philosophy of Composition"
