How does Iago plant his poison on Othello's mind about Desdemona's infidelity?
Iago manages to plant poison in Othello’s mind by doing it gradually. In Act III scene III, we can see that his plan is going well as he convinces the Moor that Desdemona are having a love affair with Cassio. These two are actually not having a love affair but Iago manages to make Othello think they are by lying and placing the handkerchief in Cassio’s room.
Iago attempts to lure Othello’s mind by saying “Ha! I like not that” (line 35). Iago tries to catch Othello’s attention by warning him. Here, Iago tries to convince Othello that something bad is going on between Desdemona and Cassio. He achieves what he wanted as Othello responds “What dost thou say?”. By saying that it is clear that Iago caught his attention.
When Desdemona tries to convince her husband that Cassio should be forgiven, Othello expresses his opinion ““Excellent wretch! Perdition catch my soul/But I do love thee; and when I love thee not, Chaos is come again” (line 90). This is dramatic irony as later on Othello will stop loving Desdemona and because of this he falls in a chaotic madness.
Iago attempts to make Othello think about Cassio and Desdemona, but then he backs out so that Othello would not be suspicious about him. This is an outstanding technique which will help Iago plant his poison on Othello’s mind. He starts by saying “Did Michael Cassio, When you wooed my lady, Know of your love?” (line 95), and when Othello suspiciously responds, he replies “But for a satisfaction of my thought, No further harm”(line 97). Here Iago manages to plant the poison with the first line, and backs up with the next line.
After, it is clear that Othello is fully vulnerable to Iago. This is because Othello shows his trust towards him “If thou dost love me, Show me thy thought” (line 116). When Iago answers “My lord, you know I love you.” (line 118), Othello
