"...Second Witch: I'll give thee a wind.
First Witch: Thou'rt kind.
Third Witch: And I another.
First Witch: I myself have all the other,
And the very ports they blow,
All the quarters that they know..."
(Act I, Scene 3, 'Macbeth', c 1606)
I understand little of Macbeth or any of Shakespeare but I was bewitched (!) by the magnificence of this picture:
Artist: John Raphael Smith, 'Macbeth', the Weird Sisters, 1785

After seeing the picture, I can't question the power of "Three Weird Sisters"...
