In Jonson’s Every Man in His Humour (acted 1598), which made this type of play popular, all the words and acts of Kitely are controlled by an overpowering suspicion that his wife is unfaithful; George Downright, a country squire, must be "frank" above all things; the country gull in town determines his every decision by his desire to "catch on" to the manners of the city gallant.
