Classifying the thousand longest rivers in the world

Alighiero Boetti and his wife, the critic Anne-Marie Sauzeau-Boetti, spent seven years attempting to establish a definitive ranking of the world’s rivers by length. Drawing upon geographical institutes and sources from around the globe, their exhaustive research culminated in this 1,016-page volume in 1977.
The project transforms the seemingly objective act of classification into an exploration of uncertainty. Conflicting measurements and the difficulty of determining where a river truly begins or ends revealed the impossibility of establishing an absolute order. Boetti embraced this contradiction: a rigorously organized system ultimately exposes the instability of the information it seeks to contain. Bringing together his enduring interests in geography, numbers and the relationship between order and disorder, the book turns the human impulse to measure and categorize the natural world into both its subject and its conceptual problem. This example comes from the first edition of just 150 copies with embroidered covers, connecting this ambitious conceptual project to the textile practice that became one of the defining elements of Boetti’s oeuvre.
