 In speaking of the character of Lady Macbeth , we ought not to pass over Mrs. Siddons 's manner of acting that part . We can conceive of nothing grander . It was something above nature . It seemed almost as if a being of a superior order had dropped from a higher sphere to awe the world with the majesty of her appearance . Power was seated on her brow , passion emanated from her breast as from a shrine ; she was tragedy personified . In coming on in the sleeping @-@ scene , her eyes were open , but their sense was shut . She was like a person bewildered and unconscious of what she did . Her lips moved involuntarily — all her gestures were involuntary and mechanical . She glided on and off the stage like an apparition . To have seen her in that character was an event in every one 's life , not to be forgotten .
