4.3 As Emilia prepares her mistress’s wedding bed, Desdemona talks of her mother’s servant Barbary who was forsaken by a mad lover, 4.3.25; then she and Emilia talk about whether they would be unfaithful to their husbands or not (4.3.60*). What is the significance of this conversation? Desdemona says she would never be unfaithful to her husband: “Beshrew [curse] me, if I would do such a wrong / For the whole world.”
4.3 What are Emilia’s thoughts on infidelity? How do they contrast with Desdemona? Emilia says, “who would not make her husband a cuckold to make him a monarch? I should venture purgatory for’t.” In other words, she would betray her husband if it meant raising their position/making him a king. She also says that women have the same desires and weaknesses as men, “And have we not affections, / Desires for sport, and frailty, as men have?” Desdemona, in contrast, would not be unfaithful to her husband “for the whole world.”
