In Edgar Allan Poe's "The Raven," how is the raven described in stanzas 12 and 13?

"" byis one of the most famous
poems in American literature, and arguably the star of the poem is a symbolic black raven who
appears to a grieving man. We know that the raven finally enters the room in stanza seven, and
then he sits, perched on a bust above the door.

In other places in the poem,
the raven is called an "ungainly fowl," an "ebony bird," and "a stately
raven." These are short descriptions which could apply to any raven.

In
the two stanzas you referenced nothing changes; man and bird are still sitting. However, in
these verses we get a more detailed description of the visiting bird. The narrator has moved his
chair so he is sitting directly in front of the raven, and then he really looks at it.

In stanza twelve, the narrator usesto describe the raven:

this grim, ungainly, ghastly, gaunt and ominous bird of yore.

In stanza thirteen, the speaker of the poem is still sitting and
looking at the strange bird. Again he uses alliteration and describes it as

the fowl whose fiery eyes now burned into my bosom's core.

These two descriptions give us a clearer picture of the strange,
symbolic bird, and he is depicted as evil. Note that nearly all of the descriptors are
indicative of something rather demonic. This image is borne out in the following stanza, when
the grieving man calls the raven a "fiend" and a
"devil."
