86.  The evidence which can be produced in support of this theory, apart from question of style and probability, is threefold.  The first proof is derived from a manuscript entitled “The Booke of Plaies and Notes thereof, for Common Pollicie,” written by a somewhat famous magician-doctor, Simon Forman, who was implicated in the murder of Sir Thomas Overbury.  He says, “In ‘Macbeth,’ at the Globe, 1610, the 20th April, Saturday, there was to be observed first how Macbeth and Banquo, two noblemen of Scotland, riding through a wood, there stood before them three women fairies, or nymphs, and saluted Macbeth, saying three times unto him, ’Hail, Macbeth, King of Codor, for thou shalt be a king, but thou shalt beget no kings,’” etc.[1] This, if Forman’s account held together decently in other respects, would be strong, although not conclusive, evidence in favour of the theory; but the whole note is so full of inconsistencies and misstatements, that it is not unfair to conclude, either that the writer was not paying marvellous attention to the entertainment he professed to describe, or that the player’s copy differed in many essential points from the present text.  Not the least conspicuous of these inconsistencies is the account of the sisters’ greeting of Macbeth just quoted.  Subsequently Forman narrates that Duncan created Macbeth Prince of Cumberland; and that “when Macbeth had murdered the king, the blood on his hands could not be washed off by any means, nor from his wife’s hands, which handled the bloody daggers in hiding them, by which means they became both much amazed and affronted.”  Such a loose narration cannot be relied upon if the text in question contains any evidence at all rebutting the conclusion that the sisters are intended to be “women fairies, or nymphs.”

87.  The second piece of evidence is the story of Macbeth as it is narrated by Holinshed, from which Shakspere derived his material.  In that account we read that “It fortuned as Makbeth and Banquho journied toward Fores, where the king then laie, they went sporting by the waie togither without other companie, saue onlie themselues, passing thorough the woods and fields, when suddenlie in the middest of a laund there met them three women in strange and wild apparell, resembling creatures of elder world, whome when they attentivelie beheld, woondering much at the sight, the first of them spake and said; ’All haile, Makbeth, thane of Glammis’ (for he had latelie entered into that dignitie and office by the death of his father Sinell).  The second of them said; ’Haile, Makbeth, thane of Cawder.’  But the third said; ’All haile, Makbeth, that heereafter shall be King of Scotland.’ ...  Afterwards the common opinion was that these women were either the weird sisters, that is (as ye would say) the goddesses of destinie, or else some nymphs or feiries, indued with knowledge of prophesie by their necromanticall science, because everiething
