Fair is foul and foul is fair:
things are not what they appear to be

 

MACBETH

ACT ONE

Scene I. An open place.

Thunder and lightning. Enter three Witches.

1 Witch. When shall we three meet again?
In thunder, lightning, or in rain?

2 Witch. When the hurlyburly's done, when the battle's lost and won.

3 Witch. That will be ere the set of sun.

1 Witch. Where the place?

2 Witch. Upon the heath.

3 Witch. There to meet with Macbeth.

1 Witch. I come, greymalkin.

2 Witch. Paddock calls.

3 Witch. Anon.

All. Fair is foul and foul is fair:

Hover through the fog and filthy air.

[Witches vanish]

Fair is foul and foul is fair: things are not what they seem.
