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. 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.
