This paper scrutinises the possibilities Martin Heidegger’s notion of ‘the event of revealing’ (Ereignis) poses for spatial theory. It shows how Heidegger’s work on ‘the event’ and its ‘fourfold’ constitution (between earth, sky, mortals and divinities) affords a spatial understanding of ontology as a site revealed around the assemblage of things. Accordingly, spatial ontologies do not grow from the multiplicity of human constructions and social relations, but from the radical ontological finitude constitutive for the revealing of the material site of the thing. Through such post‐human understanding of the event, it becomes possible to think spatiality, not just in accordance with the influence Heidegger’s thought could have on the material understanding of spatiality, but in accordance with the rich understanding we could gain by exploring the politics of finite ontologies, the politics intrinsic for the different happenings of revealing.
