Henry Fuseli, Lady Macbeth Seizing the Daggers. Exhibited 1812.  Oil on canvas, support: 1016 x 1270 mm.
MACBETH I’ll go no more:    I am afraid to think what I have done;     Look on’t again I dare not.
LADY MACBETH Infirm of purpose!     Give me the daggers: the sleeping and the dead     Are but as pictures: ‘tis the eye of childhood     That fears a painted devil. If he do bleed,     I’ll gild the faces of the grooms withal;     For it must seem their guilt. 
 - Macbeth, Act II, scene ii.
