Six Characters in Search of an Author is an Italian play by Luigi Pirandello, written and first performed in 1921. An absurdist metatheatric play about the relationship among authors, their characters, and theatre practitioners, it premiered at the Teatro Valle in Rome to a mixed reception, with shouts from the audience of "Manicomio!" ("Madhouse!") and "Incommensurabile!", a reaction to the play's illogical progression.
