s of the investigation, for their
chief title to authority would rest upon the general opinion current in
the neighbourhood in which they dwelt; but how could such an inquiry be
carried out successfully in the case of Norns? It is noticeable, too,
that Macbeth knows exactly where to find the sisters when he wants them;
and when he says--

"More shall they speak; for now I am bent to know,
By the worst means, the worst,"[2]

he makes another clear allusion to the traffic of the witches with the
devil. After the events recorded in Act IV. sc. i., Macbeth speaks of
the prophecies upon which he relies as "the equivocation of the
fiend,"[3] and the prophets as "these juggling fiends;"[4] and with
reason--for he has seen and heard the very devils themselves, the
masters of the witches and sources of all their evil power. Every point
in the play that bears upon the subject at all tends to show that
Shakspere intentionally replaced the "goddesses of Destinie" by witches;
and that the supposed Norn origin of these characters is the result of a
somewhat too great eagerness to unfold a novel and startling theory.

[Footnote 2: Mr. Fleay avoids the difficulty created by this passage,
which alludes to the witches as "the weird sisters," by supposing that
these lines were interpolated by Middleton--a method of criticism that
hardly needs comment. Act III. sc. iv. l. 134.]

100. Assuming, therefore, that the witch-nature of the sisters is
conclusively proved, it now becomes necessary to support the assertion
previously made, that good reason can be shown why Shakspere should
have elected to represent witches rather than Norns.

It is impossible to read "Macbeth" without noticing the prominence given
to the belief that witches had the power of creating storms and other
atmospheric disturbances, and that they delighted in so doing. The
sisters elect to meet in thunder, lightning, or rain. To them "fair is
foul, and foul is fair," as they "hover through the fog and filthy air."
The whole of the earlier part of the third scene of the first act is one
blast of tempest with its attendant devastation. They can loose and bind
the winds,[1] cause vessels to be tempest-tossed at sea, and mutilate
wrecked bodies.[2] They describe themselves as "posters of the sea and
land;"[3] the heath they meet upon is blasted;[4] and t
