The age and senatorial character of old Brabantio, commanded a most patient hearing from that grave assembly; but the incensed father conducted his accusation with so much intemperance, producing likelihoods and allegations for proofs, that, when Othello was called upon for his defence, he had only to relate a plain tale of the course of his love; which he did with such an artless eloquence, recounting the whole story of his wooing, as we have related it above, and delivered his speech with so noble a plainness (the evidence of truth), that the duke, who sat as chief judge, could not help confessing that a tale so told would have won his daughter too: and the spells and conjurations which Othello had used in his courtship, plainly appeared to have been no more than the honest arts of men in love; and the only witchcraft which he had used, the faculty of telling a soft tale to win a lady's ear.

This statement of Othello was confirmed by the testimony of the Lady Desdemona herself, who appeared in court, and professing a duty to her father for life and education, challenged leave of him to profess a yet higher duty to her lord and husband, even so much as her mother had shown in preferring him (Brabantio) above her father.

The old senator, unable to maintain his plea, called the Moor to him with many expressions of sorrow, and, as an act of necessity, bestowed upon him his daughter, whom, if he had been free to withhold her (he told him), he would with all his heart have kept from him; adding, that he was glad at soul that he had no other child, for this behaviour of Desdemona would have taught him to be a tyrant, and hang clogs on them for her desertion.

This difficulty being got over, Othello, to whom custom had rendered the hardships of a military life as natural as food and rest are to other men, readily undertook the management of the wars in Cyprus: and Desdemona, preferring the honour of her lord (though with danger) before the indulgence of those idle delights in which new-married people usually waste their time, cheerfully consented to his going.

No sooner were Othello and his lady landed in Cyprus, than news arrived, that a desperate tempest had dispersed the Turkish fleet, and thus the island was secure from any immediate apprehension of an attack. But the war, which Othello was to suffer, was now beginning; and the enemies, which malice stirred up against his innocent lady, proved in their nature more deadly than strangers or infidels.

Among all the general's friends no one possessed the confidence of Othello more entirely than Cassio. Michael Cassio was a young soldier, a Florentine, gay, amorous, and of pleasing address, favourite qualities with women; he was handsome and eloquent, and exactly such a person as might alarm the jealousy of a man advanced in years (as Othello in some measure was), who had married a young and beautiful wife; but Othello was as free from jealousy as he was noble, and as incapable of suspecting as of doing a base action. He had employed this Cassio in his love affair with Desdemona, and Cassio had been a sort of go-between in his suit: for Othello, fearing that himself had not those soft parts of conversation which please ladies, and finding these qualities in his friend, would often depute Cassio to go (as he phrased it) a courting for him: such innocent simplicity being rather an honour than a blemish to the character of the valiant Moor. So that no wonder, if next to Othello himself (but at far distance, as beseems a virtuous wife) the gentle Desdemona loved and trusted Cassio. Nor had the marriage of this couple made any difference in their behaviour to Michael Cassio. He frequented their house, and his free and rattling talk was no unpleasing variety to Othello, who was himself of a more serious temper: for such tempers are observed often to delight in their contraries, as a relief from the oppressive excess of their own: and Desdemona and Cassio would talk and laugh together, as in the days when he went a courting for his friend.

Othello had lately promoted Cassio to be the lieutenant, a place of trust, and nearest to the general's person. This promotion gave great offence to Iago, an older officer who thought he had a better claim than Cassio, and would often ridicule Cassio as a fellow fit only for the company of ladies, and one that knew no more of the art of war or how to set an army in array for battle, than a girl. Iago hated Cassio, and he hated Othello, as well for favouring Cassio, as for an unjust suspicion, which he had lightly taken up against Othello, that the Moor was too fond of Iago's wife Emilia. From these imaginary provocations, the plotting mind of Iago conceived a horrid scheme of revenge, which should involve both Cassio, the Moor, and Desdemona, in one common ruin.

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. Everybody 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 colour 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.
