This play is the English theatre's first 'comedy of humours', in which the attitudes, behaviour, and social pretensions of contemporary men and women are satirised. Charles Edelman's is the first fully annotated, modern spelling edition of this long-neglected play. In his extensive introduction and commentary, Edelman discusses the intellectual, philosophical and theatrical background to Chapman's comedy, and shows that An Humorous Day's Mirth would delight the readers and audiences of today as much as it did those in 1597.
