In the plays "Merry Wives of Windsor," "Henry VI," Parts 2 and 3, "King John," "Richard III" and "Othello" in the First Folio, 4,479 new lines were added after these plays were published in the Quarto editions. These Quarto editions were published from three to six years after Will Shaksper's death, and the First Folio was published seven years after his death.
Is it a coincidence that the man who inserted
these 4,479 additonal lines seven years after Will Shaksper's death
was able to copy the orignial author's style to such an extent that
it is impossible to distinguish these additions from the original
matter?
