"Design on Each Side for Waterwheel Worked by Donkey Power", Folio from a Book of the Knowledge of Ingenious Mechanical Devices by al-Jazari

Art Historical Context

This folio from a 1315 manuscript presents a detailed engineering diagram for a waterwheel powered by donkey, drawn from Badi' al-Zaman al-Jazari’s celebrated “Book of Knowledge of Ingenious Mechanical Devices.” Originally composed in 1206 for the Artuqid rulers of Diyarbakır, al-Jazari’s treatise compiled dozens of hydraulic machines, automata, and clocks. The Metropolitan’s leaf, illuminated by Farrukh ibn ʿAbd al-Latif, preserves these ideas in vibrant ink, opaque watercolor, and gold on paper, demonstrating how scientific knowledge circulated across the medieval Islamic world. The illustration combines precise technical drawing with decorative elegance typical of early fourteenth-century codices. Delicate gold highlights accentuate the wheel’s spokes and the animal’s harness, while clear labeling guides the viewer through the mechanism’s operation. Such images served both as practical blueprints for engineers and as objects of aesthetic delight for courtly readers. Beyond its mechanical ingenuity, the folio underscores the Islamic tradition’s profound contributions to science and technology. Al-Jazari’s designs influenced later European engineers, and this beautifully preserved page allows modern visitors to appreciate the blend of artistry, scholarship, and invention that flourished in the medieval Middle East.
