Which lines in this excerpt from "the raven" by edgar allan poe use allusion?
"be that word our sign of parting, bird or fiend! ” i shrieked upstarting—
"get thee back into the tempest and the night's plutonian shore!
leave no black plume as a token of that lie thy soul hath spoken!
leave my loneliness unbroken! quit the bust above my door!
take thy beak from out my heart, and take thy form from off my door! "
quoth the raven, "nevermore."
and the raven, never flitting, still is sitting, still is sitting
on the pallid bust of pallas just above my chamber door;
and his eyes have all the seeming of a demon's that is dreaming,
and the lamp-light o'er him streaming throws his shadow on the floor:
and my soul from out that shadow that lies floating on the floor
shall be lifted—nevermore!
