This article intends to examine the poetics of writing of La Lézarde, first novel written by Édouard Glissant, from the angle of the metatext. The reflexive nature of the metatext, which passes through the questioning of characters, of the writer and the reader, and is articulated around the unifying theme of the novel: filiation. Filiation is part of a historical, national, existential, generic and enunciative quest. We will show that the questioning at stake in the metatext is not only thematic or mimetic. It is formal, syntactical and stylistic, engaging the writing in a process going from meaning to significance. In other words, the metatext in La Lézarde designates a next and beyond of the text which unites two levels, and constantly works on words, on imagination, style, their relation to the world, from within, the text returning to its own enunciation. Elements intertwine and express a singular, Caribbean and poetic way of being in the world.
