El Pulso del Agua (The Pulse of the Water) documents the ambitious painting expeditions of Belgian artist Nils Verkaeren across the diverse landscapes of Colombia, eschewing the traditional studio for a “contemporary plein air” approach. Over several years, Nils Verkaeren travelled along these waterways, from the Magdalena and the Cauca to the remote rivers of the Amazon basin, working directly within the landscapes they shape. El Pulso del Agua brings together paintings and reflections that emerged from these encounters. Rather than approaching water as a motif, Verkaeren understands it as a principle, a force through which landscape reveals itself as movement, erosion, sediment, and time. Painting becomes a way of reading the territory, of entering the slow pulse of rivers that have shaped Colombia for millennia. The resulting canvases are more than mere representations; they are physical records of the journey, often carried through harsh terrain and shaped by the local climate, movement, and geography.With contributions from Colombian ecologist and academic Brigitte Baptiste and art historian Eva Wuytjens, this monograph traces Verkaeren’s immersive process, in which the act of painting becomes inseparable from the acts of travel and research. The book highlights Verkaeren’s unique ability to merge sensory experience with the natural world. By integrating the physical conditions of his environment into his work, Verkaeren transcends classical landscape traditions to create a visceral, personal dialogue with nature. This publication serves as a vital record of his exploration into how place and time shape the contemporary image.
