Who does the speaker say sent raven and what it represent in poem The Raven?

The speaker in Edgar Allan Poe's "The Raven" doesn't explicitly say who sent the raven. The bird itself claims to be a messenger from "the Night's Plutonian shore," which is a poetic way of describing the land of the dead.

However, the poem leaves room for interpretation, and some readers believe the raven could represent:

* The speaker's own subconscious: The raven's only answer is "Nevermore," which could reflect the speaker's own internal despair and hopelessness.

* A symbol of loss and grief: The speaker is grieving the loss of Lenore, and the raven's constant repetition of "Nevermore" reinforces his sense of loss.

* A supernatural force: The raven's arrival and pronouncements create an unsettling, almost mystical atmosphere.

The poem deliberately avoids a clear explanation of the raven's origin, allowing readers to draw their own conclusions about its significance and what it represents. This ambiguity adds to the poem's haunting and mysterious quality.
