Iago was artful, and had studied human nature deeply, and he knew that of all the torments which afflict the mind of man (and far beyond bodily torture), the pains of jealousy were the most intolerable, and had the sorest sting. If he could succeed in making Othello jealous of Cassio, he thought it would be an exquisite plot of revenge, and might end in the death of Cassio or Othello, or both; he cared not.
The arrival of the general and his lady in Cyprus, meeting with the news of the dispersion of the enemy's fleet, made a sort of holiday in the island. Every body gave themselves up to feasting and making merry. Wine flowed in abundance, and cups went round to the health of the black Othello, and his lady the fair Desdemona.
Cassio had the direction of the guard that night, with a charge from Othello to keep the soldiers from excess in drinking, that no brawl might arise, to fright the inhabitants, or disgust them with the new-landed forces. That night Iago began his deep-laid plans of mischief; under cover of loyalty and love to the general, he enticed Cassio to make rather too free with the bottle (a great fault in an officer upon guard). Cassio for a time resisted, but he could not long hold out against the honest freedom which Iago knew how to put on, but kept swallowing glass after glass (as Iago still plied him with drink and encouraging songs), and Cassio's tongue ran over in praise of the lady Desdemona, whom he again and again toasted, affirming that she was a most exquisite lady: until at last the enemy which he put into his mouth, stole away his brains; and upon some provocation given him by a fellow whom Iago had set on, swords were drawn, and Montano, a worthy officer, who interfered to appease the dispute, was wounded in the scuffle. The riot now began to be general, and Iago, who had set on foot the mischief, was foremost in spreading the alarm, causing the castle-bell to be rung (as if some dangerous mutiny instead of a slight drunken quarrel had arisen): the alarm-bell ringing awakened Othello, who, dressing in a hurry, and coming to the scene of action, questioned Cassio of the cause. Cassio was now come to himself, the effect of the wine having a little gone off, but was too much ashamed to reply; and Iago, pretending a great reluctance to accuse Cassio, but as it were forced into it by Othello, who insisted to know the truth, gave an account of the whole matter (leaving out his own share in it, which Cassio was too far gone to remember) in such a manner, as while he seemed to make Cassio's offence less, did indeed make it appear greater than it was. The result was, that Othello, who was a strict observer of discipline, was compelled to take away Cassio's place of lieutenant from him.
Thus did Iago's first artifice succeed completely; he had now undermined his hated rival, and thrust him out of his place: but a further use was hereafter to be made of the adventure of this disastrous night.
Cassio, whom this misfortune had entirely sobered, now lamented to his seeming friend Iago that he should have been such a fool as to transform himself into a beast. He was undone, for how could he ask the general for his place again! he would tell him he was a drunkard. He despised himself. Iago, affecting to make light of it, said, that he, or any man living, might be drunk upon occasion; it remained now to make the best of a bad bargain; the general's wife was now the general, and could do any thing with Othello; that he were best to apply to the lady Desdemona to mediate for him with her lord; that she was of a frank, obliging disposition, and would readily undertake a good office of this sort, and set Cassio right again in the general's favour; and then this crack in their love would be made stronger than ever. A good advice of Iago, if it had not been given for wicked purposes, which will after appear.
Cassio did as Iago advised him, and made application to the lady Desdemona, who was easy to be won over in any honest suit; and she promised Cassio that she would be his solicitor with her lord, and rather die than give up his cause. This she immediately set about in so earnest and pretty a manner, that Othello, who was mortally offended with Cassio, could not put her off. When he pleaded delay, and that it was too soon to pardon such an offender, she would not be beat back, but insisted that it should be the next night, or the morning after, or the next morning to that at farthest. Then she shewed how penitent and humbled poor Cassio was, and that his offence did not deserve so sharp a check. And when Othello still hung back, "What! my lord," said she, "that I should have so much to do to plead for Cassio, Michael Cassio, that came a courting for you, and oftentimes, when I have spoken in dispraise of you, has taken your part! I count this but a little thing to ask of you. When I mean to try your love indeed, I shall ask a weighty matter." Othello could deny nothing to such a pleader, and only requesting that Desdemona would leave the time to him, promised to receive Michael Cassio again into favour.
It happened that Othello and Iago had entered into the room where Desdemona was, just as Cassio, who had been imploring her intercession, was departing at the opposite door; and Iago, who was full of art, said in a low voice, as if to himself, "I like not that." Othello took no great notice of what he said; indeed the conference which immediately took place with his lady put it out of his head; but he remembered it afterwards. For when Desdemona was gone, Iago, as if for mere satisfaction of his thought, questioned Othello whether Michael Cassio, when Othello was courting his lady, knew of his love. To this the general answering in the affirmative, and adding, that he had gone between them very often during the courtship, Iago knitted his brow, as if he had got fresh light of some terrible matter, and cried, "Indeed!" This brought into Othello's mind the words which Iago had let fall upon entering the room and seeing Cassio with Desdemona; and he began to think there was some meaning in all this: for he deemed Iago to be a just man, and full of love and honesty, and what in a false knave would be tricks, in him seemed to be the natural workings of an honest mind, big with something too great for utterance: and Othello prayed Iago to speak what he knew, and to give his worst thoughts words. "And what," said Iago, "if some thoughts very vile should have intruded into my breast, as where is the palace into which foul things do not enter?" Then Iago went on to say, what a pity it were, if any trouble should arise to Othello out of his imperfect observations; that it would not be for Othello's peace to know his thoughts; that people's good names were not to be taken away for slight suspicions; and when Othello's curiosity was raised almost to distraction with these hints and scattered words, Iago, as if in earnest care for Othello's peace of mind, besought him to beware of jealousy: with such art did this villain raise suspicions in the unguarded Othello, by the very caution which he pretended to give him against suspicion. "I know," said Othello, "that my wife is fair, loves company and feasting, is free of speech, sings, plays, and dances well: but where virtue is, these qualities are virtuous. I must have proof before I think her dishonest." Then Iago, as if glad that Othello was slow to believe ill of his lady, frankly declared that he had no proof, but begged Othello to observe her behaviour well, when Cassio was by; not to be jealous, nor too secure neither, for that he (Iago) knew the dispositions of the Italian ladies, his country-women, better than Othello could do; and that in Venice the wives let heaven see many pranks they dared not shew their husbands. Then he artfully insinuated, that Desdemona deceived her father in marrying with Othello, and carried it so closely, that the poor old man thought that witchcraft had been used. Othello was much moved with this argument, which brought the matter home to him, for if she had deceived her father, why might she not deceive her husband?
Iago begged pardon for having moved him; but Othello, assuming an indifference, while he was really shaken with inward grief at Iago's words, begged him to go on, which Iago did with many apologies, as if unwilling to produce any thing against Cassio, whom he called his friend: he then came strongly to the point, and reminded Othello how Desdemona had refused many suitable matches of her own clime and complexion, and had married him, a Moor, which shewed unnatural in her, and proved her to have a headstrong will: and when her better judgment returned, how probable it was she should fall upon comparing Othello with the fine forms and clear white complexions of the young Italians her countrymen. He concluded with advising Othello to put off his reconcilement with Cassio a little longer, and in the mean while to note with what earnestness Desdemona should intercede in his behalf; for that much would be seen in that. So mischievously did this artful villain lay his plots to turn the gentle qualities of this innocent lady into her destruction, and make a net for her out of her own goodness to entrap her: first setting Cassio on to intreat her mediation, and then out of that very mediation contriving stratagems for her ruin.
The conference ended with Iago's begging Othello to account his wife innocent, until he had more decisive proof; and Othello promised to be patient: but from that moment the deceived Othello never tasted content of mind. Poppy, nor the juice of mandragora, nor all the sleeping potions in the world, could ever again restore to him that sweet rest, which he had enjoyed but yesterday. His occupation sickened upon him. He no longer took delight in arms. His heart, that used to be roused at the sight of troops, and banners, and battle-array, and would stir and leap at the sound of a drum, or a trumpet, or a neighing war-horse, seemed to have lost all that pride and ambition, which are a soldier's virtue; and his military ardour and all his old joys forsook him. Sometimes he thought his wife honest, and at times he thought her not so; sometimes he thought Iago just, and at times he thought him not so; then he would wish that he had never known of it; he was not the worse for her loving Cassio, so long as he knew it not: torn in pieces with these distracting thoughts, he once laid hold on Iago's throat, and demanded proof of Desdemona's guilt, or threatened instant death for his having belied her. Iago, feigning indignation that his honesty should be taken for a vice, asked Othello, if he had not sometimes seen a handkerchief spotted with strawberries in his wife's hand. Othello answered, that he had given her such a one, and that it was his first gift. "That same handkerchief," said Iago, "did I see Michael Cassio this day wipe his face with." "If it be as you say," said Othello, "I will not rest till a wide revenge swallow them up: and first, for a token of your fidelity, I expect that Cassio shall be put to death within three days; and for that fair devil [meaning his lady], I will withdraw and devise some swift means of death for her."
Trifles, light as air, are to the jealous proofs as strong as holy writ. A handkerchief of his wife's seen in Cassio's hand, was motive enough to the deluded Othello to pass sentence of death upon them both, without once enquiring how Cassio came by it. Desdemona had never given such a present to Cassio, nor would this constant lady have wronged her lord with doing so naughty a thing, as giving his presents to another man; both Cassio and Desdemona were innocent of any offence against Othello: but the wicked Iago, whose spirits never slept in contrivance of villainy, had made his wife (a good, but a weak woman) steal this handkerchief from Desdemona, under pretence of getting the work copied, but in reality to drop it in Cassio's way, where he might find it, and give a handle to Iago's suggestion that it was Desdemona's present.
