Daniele Del Giudice's novels, and the second part of Jose Saramago's novelistic work, are built around a neutral event, happening surprisingly and beyond the possibilities contained by the diegetic world. Such an event can be considered as « événemential » in the terms of Claude Romano's philosophical analysis. This thesis examines the place of such an event in the poetics of the two writers, studies its diegetic and narrative specificities as well as the characteristics of its use, and analyses its implications in giving shape to the world figured by the novels.The use of such an event is part of the search of a possible narration begun by the two writers in the early 1980's : this event disrupts the traditional novelistic pattern by drawing attention to a process of happening that is indeterminate and constantly disrupted, all the while providing a narrative dynamic that disturbs its own organisational logic. Both writers aim to expose the movement of the happening, echoing the extra-diegetic reality. The latter appears as woven from a multiplicity of unstable elements which combine to form a changing totality. The narrative shows its relational structure and its dynamic. An experience that is both tangible and visible is created, anchored in the specificities of language and narration, in a way that offers a perspective on the structuring of the sensory world.The use and role of the event in the two writer's novels reveals shared concerns and gestures towards a tendency of contemporary narrativisation : the desire to make palpable the dynamics of an indetermined, aimless and uncertain happening, while rendering in and through narrative the force of a presence.
