The project Hydroformations follows the river Rhine and the soggy wetlands of Arnhem. Earthly waters are very special environments and ecosystems – holding a culturally paradoxical position. On the one hand, all life on Earth comes from water and is interpenetrated by water. That vital aspect is mirrored by the recognition of water bodies and especially rivers by various Indigenous systems of knowledge, including ancient and up to medieval cultures inhabiting what we know today as Europe. Archaeologist and EH scholar Christina Fredengren argues, for instance, that the deposition of dead human and animal bodies as well as artefacts in water bodies in Western and Northern Europe -  interpreted as a sacrifice to the watery deities and spirits - may actually be connected to “an acknowledgement that these watery environments were alive with personhood, and that these deposited ‘things’, such as neck-rings or swords, in fact contributed towards the extension of such personhood, and were di­rected at watery more-than-human persons or perhaps deities, but as such, more immanently present in this world” (Fredengren 2018: 221). We may see thus a question of water personhood running across various cultures and cosmologies around the world. Yet, on the other hand, (in the primarily Western context) water bodies, and especially seas and oceans, are culturally coded as spaces of forgetting: out of sight, out of mind. This is directly expressed through treating oceans and seas (and at times, also rivers) as a destination for waste dumping, including the toxic, chemical and military one. It is primarily that aspect that my keynote will speak to. In this lecture, I will focus on the questions of environmental violence and ecocide, on the one hand, and the interlinked societal responses in a form of cultural expressions and arts of eco-grief. Simultaneously, I will also link my presentation to critical frameworks of low-trophic theory (Radomska and Åsberg 2021) and terminal ecologies/queer lasting (Ensor 2019, 2025). The hope is to demonstrate how - by telling visual and textual stories of ecocide - one may be able to acknowledge the gravity of violence, allow oneself to mourn, and activate different, more caring ethical imaginaries.
