Dame Pliant’s brother. A kestrel is a type of falcon that is known to aggressively beat its wings while hunting for prey on the ground, and Jonson’s Kestrel is similarly aggressive. Kestrel’s friend, Abel Drugger, takes him to see Subtle because they believe Subtle is an accomplished alchemist and mystic who can teach Kestrel to quarrel and live by his wits. Kestrel basically wants to be independently wealthy and intimidate others, like he does to his sister, whom he intends on marrying off to a rich aristocrat. Kestrel is cruel to Dame Pliant and threatens to beat and “maul” her if she doesn’t do as he says. He forces her to kiss and entertain Face and Subtle, and when Surly arrives disguised as a Spanish count, Kestrel makes Dame Pliant agree to marry him. After Surly admits that he isn’t really Spanish and that Subtle and Face are really conmen, Kestrel uses his new quarreling skills to chase Surly away. He chases Surly down the street, where he presumably learns the truth about Subtle and Face’s scam. Kestrel returns to the house to get his sister, but he is met by Lovewit, who has already married Dame Pliant in his absence. Kestrel is furious and attempts to use his quarreling skills on Lovewit, but Kestrel is quickly intimidated and shut up. Kestrel represents gullibility and greed in Jonson’s play. He easy falls for Subtle and Face’s con, and he seeks Subtle’s help as an alchemist to selfish ends. Kestrel’s greed is also mirrored in his despicable treatment of his sister, whom he sees largely as an object that can bring him increased wealth and status.
