This work emerges from a personal research experience in Venice and offers an eco-critical reading of the lagoon as both an ecosystem and an epistemic space. Water is understood as a site of knowledge and a cultural agent: a living matter that shapes thought, relationships, and imagination. Drawing primarily on the Blue Humanities and hydofeminism, the research explores the lagoon in its continuous transformation, questioning its capacity to generate forms of coexistence among bodies, environments, and more-than-human lives. The methodology is grounded in situated and embodied knowledge, developed through attentive listening to the territory and encounters with those who inhabit it. Venice is conceived as an aquapelago (a concept developed within Island Studies), that is, a system in which the “water” component is at least as significant as the “land” component in terms of interconnection. The project brings together experiences of walking and navigation, embodied practices such as rowing, interviews with curators and local initiatives, and experiments that transform the boat into a liminal space of observation and learning. Thinking with water entails adopting a porous and decentered stance, one that embraces uncertainty and drift as generative conditions. Inhabiting the lagoon through practices of care and listening opens up forms of shared knowledge, where every gesture oriented toward mutual attentiveness becomes a practice of liquid resistance and a space of common life.
