A raven and guard at the Tower of London. According to superstition, there must always be 6 ravens present at the Tower, or else the monarchy, kingdom, and Tower itself will fall. In "The Tudors," when Anne was executed, you can see her look up at the flying ravens overhead. In actuality, they all stopped flight and sat on the edge of the Tower as she lost her head...something eyewitness accounts of the execution described as not only eerie, but highly unusual.
Then this ebony bird beguiling my sad fancy into smiling, By the grave and stern decorum of the countenance it wore, `Though thy crest be shorn and shaven, thou,' I said, `art sure no craven. Ghastly grim and ancient raven wandering from the nightly shore - Tell me what thy lordly name is on the Night's Plutonian shore!' Quoth the raven, `Nevermore.'
The Raven | 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!
