I think the sun where he was born
Drew all such humours from him.

– William Shakespeare

Othello, Act 3, Scene 4. With much irony, a naive and too trusting Desdemona insists to Emilia that Othello is not a jealous man. But her emotions blind her to the reality of the situation and the imminent danger it puts her in. The husband she doesn’t know as well as she thinks is intensely jealous because of a supposed affair she is having with Cassio.
