Then said Bancko, What all to Mackbeth And nothing to me. Yes, said the nimphes, haille to thee Bancko, thou shalt beget kinges, yet be no kinge. And so they departed & cam to the Courte of Scotland to Dunkin king of Scotes, and yt was in the dais of Edward the Confessor. And Dunkin bad them both kindly wellcome, And made Mackbeth forth with Prince of Northumberland, and sent him hom to his own castell, and appointed Mackbeth to prouid for him, for he would sup with him the next dai at night, & did soe. And Mackebeth contrived to kill Dunkin, & thorowe the persuasion of his wife did that night Murder the kinge in his own Castell, beinge his guest. And ther were many prodigies seen that night & the dai before. And when Mack Beth had murdred the kinge, the blod on his handes could not be washed of by Any meanes, nor from his wiues handes, which handled the bloddi daggers in hiding them, By which means they became both moch amazed & Affronted. The murder being knowen, Dunkins 2 sons fled, the on to England, the [other to] Walles, to saue them selues, they being fled, they were supposed guilty of the murder of their father, which was nothinge so. Then was Mackbeth crowned kinge, and then he for feare of Banko, his old companion, that he should beget kinges but be no kinge him selfe, he contriued the death of Banko, and caused him to be Murdred on the way as as he Rode. The next night, beinge at supper with his noble men whom he had bid to a feaste to the which also Banco should haue com, he began to speake of Noble Banco, to wish that he wer ther. And as he thus did, standing vp to drincke a Carouse to him, the ghoste of Banco came and sate down in his cheier behind him. And he turninge About to sit down Again sawe the goste of Banco, which fronted him so, that he fell into a great passion of fear and fury, Vtterynge many wordes about his murder, by which, when they hard that Banco was Murdred they Suspected Mackbet.

Comments: Simon Forman (1552-1611) was an Elizabethan astrologer, whose manuscripts include the ‘Booke of Plaies‘ with Forman’s impressions of four plays that he saw in London 1610-11, three of which were productions of Shakespeare. Though some have argued that the document is a forgery, it is generally accepted as authentic. It is also accepted that Forman got the year of the performance wrong, and it should be 1611.
