This dissertation is a study and critical edition of Antonio Hurtado de Mendoza's comedy Cada loco con su tema. The introduction presents a short biography of the playwright, comments on his other plays, analyzes the major themes and ideas of this work, and presents the criteria used in preparing this edition. The basis of the text is a microfilm copy of the autograph manuscript (signed and dated August 29, 1630), located in the Biblioteca Nacional in Madrid. This manuscript was collated with two other early manuscript and the three printed editions. The text of the play retains the orthography of the autograph manuscript but has adjusted the capitalization and punctuation to modern norms. The notes list the variants from the other copies and explain difficult passages. Also included are a table of versification and bibliography
