The Humorous Courtier, also called The Duke, is a Caroline era stage play, a comedy written by James Shirley, first published in 1640.
The Humorous Courtier was licensed for performance by Sir Henry Herbert, the Master of the Revels, on 17 May 1631, under the title The Duke.[1] Like most of Shirley's plays, it was acted by Queen Henrietta's Men at the Cockpit Theatre. As The Humorous Courtier, the play was entered into the Stationers' Register on 29 July 1639. The 1640 quarto, printed by Thomas Cotes for the bookseller William Cooke, contains an interesting bibliographic feature in its prefatory material: a catalogue of 20 plays by Shirley published to that date.[2] Such catalogues were only then coming into existence. (Since Cooke had already published a number of Shirley's plays, this promotional catalogue served his own interest.)
As its title indicates, the play is a humors comedy. That subgenre was initiated by George Chapman with his An Humorous Day's Mirth (1597), but is most strongly associated with Ben Jonson, whose plays Every Man in His Humour and Every Man Out of His Humour defined the form. Later writers also worked in the humors vein, as John Fletcher did in his tragicomedy The Humorous Lieutenant (c. 1619). As the Duchess of Mantua says of her courtiers, "They are mad humours, and I must physic them."
