Abstract: In what way can two dramaturgies and two personalities as dissimilar as those of Giraudoux and Eduardo De Filippo reveal touchstones that allow a rereading of each in the light of the other and the discovery of thematic and poetic affinities? From the Pirandellian parallelism that unites these two works, here is a reflection on the twofold plane of poetics and language, their similar conceptions of writing, and the goals of the art of theater.
