Three further passages (4.3.87–106, 5.2.176–79, 5.2.217–20) considerably flesh out the character of Emilia. Most powerful is the extraordinary defense of woman in Act 4 Scene 3:

But I do think it is their husbands’ faults
If wives do fall…
… And have not we affections?
Desires for sport? And frailty, as men have?

The introduction of this plea for recognition of female bodily desire and for an end to the double standard over adultery makes an enormous difference to the play. That Shakespeare seems to have written it not in his first draft but in response to theatrical need is most revealing.

If you look at printers’ handbooks from the age of Shakespeare, you quickly discover that one of the first rules was that, whenever possible, compositors were recommended to set their type from existing printed books rather than manuscripts. This was the age before mechanical typesetting, where each individual letter had to be picked out by hand from the compositor’s case and placed on a stick (upside down and back to front) before being laid on the press. It was an age of murky rush-light and of manuscripts written in a secretary hand that had dozens of different, hard-to-decipher forms. Printers’ lives were a lot easier when they were reprinting existing books rather than struggling with handwritten copy. Easily the quickest way to have created the First Folio would have been simply to reprint those eighteen plays that had already appeared in Quarto and only work from manuscript on the other eighteen.

But that is not what happened. Whenever Quartos were used, playhouse “promptbooks” were also consulted and stage directions copied in from them. And in the case of several major plays where a reasonably well-printed Quarto was available, the Folio printers were instructed to work from an alternative, playhouse-derived manuscript. This meant that the whole process of producing the first complete Shakespeare took months, even years, longer than it might have done. But for the men overseeing the project, John Hemings and Henry Condell, friends and fellow actors who had been remembered in Shakespeare’s will, the additional labor and cost were worth the effort for the sake of producing an edition that was close to the practice of the theater. They wanted all the plays in print so that people could, as they wrote in their prefatory address to the reader, “read him and again and again,” but they also wanted “the great variety of readers” to work from texts that were close to the theater life for which Shakespeare originally intended them. For this reason, the RSC Shakespeare, in both Complete Works and individual volumes, uses the Folio as base text wherever possible. Significant Quarto variants are, however, noted in the Textual Notes and Quarto-only passages are appended after the text of Othello.

The following notes highlight various aspects of the editorial process and indicate conventions used in the text of this edition:

Lists of Parts are supplied in the First Folio for only six plays, one of which is Othello, so the list at the beginning of the play is reproduced from the First Folio with minor editorial adjustments. Capitals indicate that part of the name which is used for speech headings in the script (thus OTHELLO, the Moor).

Locations are provided by the Folio for only two plays. Eighteenth-century editors, working in an age of elaborately realistic stage sets, were the first to provide detailed locations. Given that Shakespeare wrote for a bare stage and often an imprecise sense of place, we have relegated locations to the explanatory notes at the foot of the page, where they are given at the beginning of each scene where the imaginary location is different from the one before. We have emphasized broad geographical settings (Venice and Cyprus) rather than specifics of the kind that suggest anachronistically realistic staging. We have therefore avoided such niceties as “another room in the palace.”

Act and Scene Divisions were provided in the Folio in a much more thoroughgoing way than in the Quartos. Sometimes, however, they were erroneous or omitted; corrections and additions supplied by editorial tradition are indicated by square brackets. Five-act division is based on a classical model, and act breaks provided the opportunity to replace the candles in the indoor Blackfriars playhouse which the King’s Men used after 1608, but Shakespeare did not necessarily think in terms of a five-part structure of dramatic composition. The Folio convention is that a scene ends when the stage is empty. Nowadays, partly under the influence of film, we tend to consider a scene to be a dramatic unit that ends with either a change of imaginary location or a significant passage of time within the narrative. Shakespeare’s fluidity of composition accords well with this convention, so in addition to act and scene numbers we provide a running scene count in the right margin at the beginning of each new scene, in the typeface used for editorial directions. Where there is a scene break caused by a momentary bare stage, but the location does not change and extra time does not pass, we use the convention running scene continues. There is inevitably a degree of editorial judgment in making such calls, but the system is very valuable in suggesting the pace of the plays.

Speakers’ Names are often inconsistent in Folio. We have regularized speech headings, but retained an element of deliberate inconsistency in entry directions, in order to give the flavor of Folio.

Verse is indicated by lines that do not run to the right margin and by capitalization of each line. The Folio printers sometimes set verse as prose, and vice versa (either out of misunderstanding or for reasons of space). We have silently corrected in such cases, although in some instances there is ambiguity, in which case we have leaned toward the preservation of Folio layout. Folio sometimes uses contraction (“turnd” rather than “turned”) to indicate whether or not the final “-ed” of a past participle is sounded, an area where there is variation for the sake of the five-beat iambic pentameter rhythm.
