It should be observed that at the close of the Banquet scene, where she has gone through much less, she is evidently exhausted.

Shakespeare, of course, knew whether he meant the faint to be real:  but I am not aware if an actor of the part could show the audience whether it was real or pretended.  If he could, he would doubtless receive instructions from the author.

NOTE EE.

DURATION OF THE ACTION IN MACBETH.  MACBETH’S AGE.  ’HE HAS NO CHILDREN.’

1.  The duration of the action cannot well be more than a few months.  On the day following the murder of Duncan his sons fly and Macbeth goes to Scone to be invested (II. iv.).  Between this scene and Act III. an interval must be supposed, sufficient for news to arrive of Malcolm being in England and Donalbain in Ireland, and for Banquo to have shown himself a good counsellor.  But the interval is evidently not long:  e.g. Banquo’s first words are ‘Thou hast it now’ (III. i. 1).  Banquo is murdered on the day when he speaks these words.  Macbeth’s visit to the Witches takes place the next day (III. iv. 132).  At the end of this visit (IV. i.) he hears of Macduff’s flight to England, and determines to have Macduff’s wife and children slaughtered without delay; and this is the subject of the next scene (IV. ii.).  No great interval, then, can be supposed between this scene and the next, where Macduff, arrived at the English court, hears what has happened at his castle.  At the end of that scene (IV. iii. 237) Malcolm says that ’Macbeth is ripe for shaking, and the powers above put on their instruments’:  and the events of Act V. evidently follow with little delay, and occupy but a short time.  Holinshed’s Macbeth appears to have reigned seventeen years:  Shakespeare’s may perhaps be allowed as many weeks.

But, naturally, Shakespeare creates some difficulties through wishing to produce different impressions in different parts of the play.  The main effect is that of fiery speed, and it would be impossible to imagine the torment of Macbeth’s mind lasting through a number of years, even if Shakespeare had been willing to allow him years of outward success.  Hence the brevity of the action.  On the other hand time is wanted for the degeneration of his character hinted at in IV. iii. 57 f., for the development of his tyranny, for his attempts to entrap Malcolm (ib. 117 f.), and perhaps for the deepening of his feeling that his life had passed into the sere and yellow leaf.  Shakespeare, as we have seen, scarcely provides time for all this, but at certain points he produces an impression that a longer time has elapsed than he has provided for, and he puts most of the indications of this longer time into a scene (IV. iii.) which by its quietness contrasts strongly with almost all the rest of the play.
