This article aims to deepen the idea of Fernando Pessoa as a dramatist. To achieve this, it favors an approach that is still little explored by critics, which is to focus less on the analysis of the literary elements and more on the scenic elements of the author’s best-known play, The Mariner. Without denying the link between this play and the symbolist imagery (including the dramatic work of Maurice Maeterlinck, with which Pessoa’s plays are systematically associated), an attempt is made to broaden the spectrum of approach towards the multiple tradition of modern and contemporary drama, in terms in which this is outlined by Jean-Pierre Sarrazac.
