Themes are the fundamental and often universal ideas explored in a literary work.
Before and above all else, Othello is a soldier. From the earliest moments in the play, his career affects his married life. Asking “fit disposition” for his wife after being ordered to Cyprus (I.iii.234), Othello notes that “the tyrant custom . . . / Hath made the flinty and steel couch of war / My thrice-driven bed of down” (I.iii.227–229). While Desdemona is used to better “accommodation,” she nevertheless accompanies her husband to Cyprus (I.iii.236). Moreover, she is unperturbed by the tempest or Turks that threatened their crossing, and genuinely curious rather than irate when she is roused from bed by the drunken brawl in Act II, scene iii. She is, indeed, Othello’s “fair warrior,” and he is happiest when he has her by his side in the midst of military conflict or business (II.i.179). The military also provides Othello with a means to gain acceptance in Venetian society. While the Venetians in the play are generally fearful of the prospect of Othello’s social entrance into white society through his marriage to Desdemona, all Venetians respect and honor him as a soldier. Mercenary Moors were, in fact, commonplace at the time.
Othello predicates his success in love on his success as a soldier, wooing Desdemona with tales of his military travels and battles. Once the Turks are drowned—by natural rather than military might—Othello is left without anything to do: the last act of military administration we see him perform is the viewing of fortifications in the extremely short second scene of Act III. No longer having a means of proving his manhood or honor in a public setting such as the court or the battlefield, Othello begins to feel uneasy with his footing in a private setting, the bedroom. Iago capitalizes on this uneasiness, calling Othello’s epileptic fit in Act IV, scene i, “[a] passion most unsuiting such a man.” In other words, Iago is calling Othello unsoldierly. Iago also takes care to mention that Cassio, whom Othello believes to be his competitor, saw him in his emasculating trance (IV.i.75).
Desperate to cling to the security of his former identity as a soldier while his current identity as a lover crumbles, Othello begins to confuse the one with the other. His expression of his jealousy quickly devolves from the conventional—“Farewell the tranquil mind”—to the absurd:
Farewell the plum’d troops and the big wars
That make ambition virtue! O, farewell,
Farewell the neighing steed and the shrill trump,
The spirit-stirring drum, th’ear piercing fife,
The royal banner, and all quality,
Pride, pomp, and circumstance of glorious war!”
One might well say that Othello is saying farewell to the wrong things—he is entirely preoccupied with his identity as a soldier. But his way of thinking is somewhat justified by its seductiveness to the audience as well. Critics and audiences alike find comfort and nobility in Othello’s final speech and the anecdote of the “malignant and . . . turbaned Turk” (V.ii.362), even though in that speech, as in his speech in Act III, scene iii, Othello depends on his identity as a soldier to glorify himself in the public’s memory, and to try to make his audience forget his and Desdemona’s disastrous marital experiment.
The action of Othello moves from the metropolis of Venice to the island of Cyprus. Protected by military fortifications as well as by the forces of nature, Cyprus faces little threat from external forces. Once Othello, Iago, Desdemona, Emilia, and Roderigo have come to Cyprus, they have nothing to do but prey upon one another. Isolation enables many of the play’s most important effects: Iago frequently speaks in soliloquies; Othello stands apart while Iago talks with Cassio in Act IV, scene i, and is left alone onstage with the bodies of Emilia and Desdemona for a few moments in Act V, scene ii; Roderigo seems attached to no one in the play except Iago. And, most prominently, Othello is visibly isolated from the other characters by his physical stature and the color of his skin. Iago is an expert at manipulating the distance between characters, isolating his victims so that they fall prey to their own obsessions. At the same time, Iago, of necessity always standing apart, falls prey to his own obsession with revenge. The characters cannot be islands, the play seems to say: self-isolation as an act of self-preservation leads ultimately to self-destruction. Such self-isolation leads to the deaths of Roderigo, Iago, Othello, and even Emilia.
