Would you dye a raven black? [ Proverb ]

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 lamplight over 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. [ Poe ]

Day is a snow-white Dove of heaven
That from the East glad message brings:
Night is a stealthy, evil Raven,
Wrapt to the eyes in his black wings. [ T. B. Aldrich ]

Whiter than new snow on a raven's back. [ William Shakespeare ]

How sweetly did they float upon the wings
Of silence through the empty-vaulted night.
At every fall smoothing the raven down
Of darkness till it smiled! [ Milton ]

The Raven's house is built with reeds, -
Sing woe, and alas is me!
And the Raven's couch is spread with weeds,
High on the hollow tree;
And the Raven himself, telling his beads
In penance for his past misdeeds.
Upon the top I see. [ Thos. Darcy McGee ]

The croaking raven doth bellow for revenge. [ William Shakespeare ]

The raven said to the rook, stand away black coat. [ Proverb ]
