The Re-echo Club: as by Edgar Allan Poe (Purple Cow)

Open then I flung a shutter,
And, with many a flirt and flutter,
In there stepped a Purple Cow which gayly tripped around my floor.
Not the least obeisance made she,
Not a moment stopped or stayed she,
But with mien of chorus lady perched herself above my door.
On a dusty bust of Dante perched and sat above my door.

And that Purple Cow unflitting
Still is sitting--still is sitting
On that dusty bust of Dante just above my chamber door,
And her horns have all the seeming
Of a demon's that is screaming,
And the arc-light o'er her streaming
Casts her shadow on the floor.
And my soul from out that pool of Purple Shadow on the floor
Shall be lifted Nevermore!
