In recent years, many authors around the world have taken on the difficult task of commemorating the unmourned dead caused by wars, terrorism or structural violence, or of giving them a literary burial. Their fictions, which I will call thanatographical fiction in the following, play a central role for the collective imaginary in that they provide an archive of knowledge on how violent death and grief are processed. The study of a comparative corpus shows that there is a transcultural and transmedial poetics of grief that serves to frame and channel emotions, to give them a form that allows access to them without sparking further excess. What I aim to demonstrate is that the common grounds of fictions from such diverse places as France, Québec, Senegal and Ukraine are that they can illustrate processes of the economy of emotions: in order to address the subject of violent death, they have to resort to different strategies of emotion control. By modulating emotions, texts and films influence both the regulation of grief and commemoration on one hand, and on the other, the reinforcement of collective identities. They can thus provide an instrument for reflecting on the interaction of grief and violence to gain a better understanding of it. I will thus analyse Wajdi Mouawad’s tetralogy of plays Le sang des promesses, Mohamed Mbougar Sarr’s novel De purs hommes, Valentyn Vasyanovych’s film Atlantis and Julie Ruocco’s novel Furies to elaborate a first draft of a thanatographical poetics of grief.
