This research-creation thesis presents an intimist poetry collection and a phenomenological reflection in connection with the theme of the horizon. The poetic approach articulates an existential and ontological quest, which is part of a landscape discovery dynamic, associated with a metaphysical reflection on the sense of Being-in-the-world. Poems are composed in free verse and marry the movement of a lyrical subject in his march toward the horizon. Designed into four sections, the collection proposes a path from death, figuratively, to the horizon of being and meaning, which emerges in the light of the dawn. The essay discusses the poetic and intimist experience of the lyrical subject, which is manifested as a presence-absence through the self-renunciation, objectification and silence, withdrew from reality in solitude. The non-being condition, combined with death, allows the subject to listen to the poetic voice and approach the radical otherness, represented by the themes of the voice, the other and the horizon. The mode of habitat associated to the intimism poet, embodied into the landscape, is modulated in an in-between, which oscillates from self-expression and unobtrusiveness or silent distance, emotion and intelligibility, here and elsewhere, in order to fulfill the ontological quest.
